For buyers specifically seeking a renewed Mac Pro desktop, these two Late 2013 models share a compact aluminum design, a quad-core Xeon processor, dual FirePro D300 graphics, and 512 GB of flash storage. My lead pick is the 64 GB model because its larger memory capacity gives demanding older workflows more room to operate, while the 16 GB model is the simpler choice for lighter tasks and buyers who do not need as much RAM. Both are older Intel workstations, though, and their software age, limited internal expansion, and legacy ports matter more than their original premium positioning. I rank them by practical workload flexibility, then weigh operating-system age, connection options, and refurbishment details so you can decide whether either fits your setup.

Apple Mac Pro (Late 2013), 3.7 GHz Quad-Core Xeon, 64 GB RAM, 512 GB SSD (Renewed)
I rank this configuration first because 64 GB of ECC memory addresses the biggest practical difference between the two listings. The processor and dual FirePro D300 graphics match the 16 GB model, so extra RAM does not make the CPU newer or change the graphics generation. It does give compatible applications more space for large projects and lets buyers keep more work open before memory becomes a limiting factor. For a renewed Mac Pro intended to remain useful with demanding older software, that capacity is the more flexible starting point.
The rest of the specification is recognizably Late 2013: a 3.7 GHz quad-core Xeon E5-1620 v2, 512 GB SSD, six Thunderbolt 2 ports, four USB 3.0 ports, HDMI 1.4, and dual Gigabit Ethernet. Those ports can suit a workstation built around older external drives, displays, or network connections, but they are not a substitute for modern high-bandwidth standards. The compact cylinder also offers limited internal expansion, so I would plan around external storage and verify that existing peripherals can connect without awkward adapters.
Compared with the 16 GB model, this listing has two advantages beyond memory: it states macOS Sierra rather than Yosemite and specifies accessories plus a minimum 90-day refurbished warranty. Neither detail makes the machine current, and a stated minimum warranty is not a promise of long-term support. I would still confirm the seller’s exact condition, included items, return terms, and whether the installed system can run the applications required. The listing’s dimensions are also given as 12 inches on each side, unlike the compact measurements in the other listing; confirm the actual unit’s form factor and specifications with the seller.
This is the stronger choice when the priority is memory headroom in a legacy Mac workstation. It is a poor match for current professional software that requires recent macOS versions, modern graphics, or newer connectivity. The old quad-core processor remains a shared ceiling across both options, and the internal upgrade path is narrow. I would choose it over the 16 GB Mac Pro for memory-intensive, compatible work; for light use where 16 GB is sufficient, the extra RAM may not justify choosing this configuration.
Pros:- 64 GB of 1866 MHz DDR3 ECC memory offers substantially more capacity than the other listing’s 16 GB.
- 512 GB SSD and dual FirePro D300 graphics match the core storage and graphics configuration of the comparison model.
- Six Thunderbolt 2 ports, four USB 3.0 ports, HDMI 1.4, and dual Gigabit Ethernet provide several legacy workstation connections.
- Listing specifies accessories and a minimum 90-day refurbished warranty.
Cons:- Late 2013 quad-core hardware and dual D300 graphics are old relative to current workstation systems.
- macOS Sierra is dated, and the limited internal expansion makes future upgrades less flexible.
- The listing’s stated dimensions differ from the other model’s measurements, so configuration details should be verified before ordering.
Best for: A buyer who needs a compact Intel Mac for compatible legacy applications, values 64 GB ECC memory for larger projects, and can work with Thunderbolt 2-era peripherals.
Not ideal for: Anyone who needs current macOS support, a recent processor or GPU, easy internal upgrades, or modern Thunderbolt connectivity.
- Processor:3.7 GHz quad-core Intel Xeon E5-1620 v2
- Memory:64 GB 1866 MHz DDR3 ECC SDRAM
- Storage:512 GB SSD
- Graphics:Dual AMD FirePro D300, 2 GB GDDR5 each
- Operating system:macOS Sierra
- Ports:6 Thunderbolt 2, 4 USB 3.0, HDMI 1.4
- Networking:Dual Gigabit Ethernet, 802.11ac Wi-Fi, Bluetooth 4.0
- Warranty:Minimum 90-day refurbished warranty
Our verdict“I would choose this 64 GB configuration over the 16 GB model for memory-heavy compatible work, while treating its old software platform and limited expansion as firm constraints.”
Apple Mac Pro Desktop Computer, 3.7 GHz Quad-Core Intel Xeon E5, 16 GB RAM, 512 GB SSD (Renewed)
This renewed Mac Pro keeps the same defining Late 2013 hardware pattern as my top pick: a 3.7 GHz quad-core Xeon, dual AMD FirePro D300 graphics, and 512 GB of flash storage. Its place in the ranking comes down mainly to its 16 GB of ECC memory. That can be adequate for lighter compatible tasks, basic workstation duties, or a focused setup with few applications open, but it leaves less headroom than the 64 GB configuration when projects or multitasking needs grow.
The machine’s most useful distinction is that its storage is specified as 512 GB PCIe flash, alongside six Thunderbolt 2 ports and four USB 3.0 ports. That combination can suit someone who already owns compatible external drives and older peripherals. It does not fix the larger limitations shared with the 64 GB Mac Pro: Thunderbolt 2 is an older standard, the internal expansion path is constrained, and OS X Yosemite is far behind current macOS releases. Buyers should check whether their applications, security requirements, and accessories are compatible before committing.
Compared with the 64 GB listing, this model is easier to justify when the task does not need more memory and the buyer values the specified compact measurements of 9.9 inches tall by 6.6 inches in diameter. However, it gives up 48 GB of RAM, lists the older OS X Yosemite system, and does not include a stated warranty in the supplied product details. That absence does not prove there is no coverage; it means I would verify the seller’s warranty and return terms directly rather than assume they match the other listing.
I would treat this as a purpose-specific older Mac, not a low-cost route to modern workstation performance. It makes more sense than the 64 GB unit if a known legacy workflow runs well within 16 GB and its ports fit the existing setup. Skip it if you expect to edit large media projects, run several memory-hungry applications, or rely on current operating-system support. The processor and graphics generation are shared, so paying attention to software compatibility and refurbishment condition matters more than the workstation label.
Pros:- 3.7 GHz quad-core Xeon and dual FirePro D300 graphics provide a workstation-oriented configuration for compatible older software.
- 512 GB PCIe flash storage is specified, matching the other model’s capacity.
- Six Thunderbolt 2 ports and four USB 3.0 ports support a range of older external devices.
- Compact listed dimensions may suit a desk with limited space.
Cons:- 16 GB of ECC memory is far below the 64 GB configuration in the other listing.
- The specified OS X Yosemite installation is very old and may restrict application and security support.
- No warranty duration is provided in the supplied product details, so coverage needs direct confirmation.
Best for: A buyer with a known, modest legacy Mac workload who needs the listed Thunderbolt 2 and USB 3.0 connections and does not need more than 16 GB of memory.
Not ideal for: A buyer running large memory-intensive projects, needing current macOS compatibility, or expecting a clearly stated warranty without checking the listing.
- Processor:3.7 GHz quad-core Intel Xeon E5
- Memory:16 GB 1866 MHz DDR3 ECC
- Storage:512 GB PCIe flash SSD
- Graphics:Dual AMD FirePro D300, 2 GB GDDR5 VRAM each
- Operating system:OS X Yosemite
- Wireless:802.11ac Wi-Fi, Bluetooth 4.0
- Ports:6 Thunderbolt 2, 4 USB 3.0
- Dimensions:9.9 in tall × 6.6 in diameter
Our verdict“I would select this model only for a defined, lighter legacy workload that fits within 16 GB and can use its older operating system and ports.”
How We Picked
I ranked these two renewed Mac Pro desktops around the decisions that matter when buying a decade-old workstation: memory capacity, usable connections, software condition, and refurbishment clarity. Since both listings describe the same 3.7 GHz quad-core Xeon class, dual AMD FirePro D300 graphics, and 512 GB SSD capacity, I did not treat their shared components as a reason to declare one automatically faster. The clear hardware distinction is RAM: the 64 GB configuration can accommodate larger memory demands and more concurrent applications than the 16 GB option.
I also weighed what the specifications cannot settle. A renewed computer’s actual condition, included accessories, battery-free desktop setup, and seller support should be confirmed on the live listing before purchase. The 64 GB product description names a minimum 90-day warranty; the other product information does not provide the same assurance. Finally, I considered the age of the stated operating systems and the machines’ Thunderbolt 2-era connectivity. These picks suit buyers with a defined reason to use an older Intel Mac Pro, not shoppers who simply want a current, broadly supported Mac desktop.
| renewed mac pro desktop | Graphics | Operating system |
|---|---|---|
| Apple Mac Pro | Dual AMD FirePro D300, 2 GB GDDR5 each | macOS Sierra |
| Apple Mac Pro Desktop Computer | Dual AMD FirePro D300, 2 GB GDDR5 VRAM each | OS X Yosemite |
Factors to Consider When Choosing Renewed Mac Pro Desktops
I would start by asking whether a renewed 2013 Mac Pro fits a specific existing workflow. These two options share much of their core hardware, so the decision is less about picking a universally modern workstation and more about matching memory, software, connections, and refurbishment details to a known need.Choose memory for the work you actually run
The clearest difference is 16 GB versus 64 GB of ECC memory. More RAM helps when an application works with large files or when several applications must stay open together; it does not make the quad-core processor newer or guarantee a faster result in every task. If the intended workload already fits comfortably within 16 GB, the lower-memory model may be sufficient. If memory pressure is a known problem, the 64 GB listing is the more capable choice of these two. I would not buy either configuration assuming the memory alone makes it suitable for current high-end production work.
Check software age before choosing the computer
The supplied specifications list OS X Yosemite on the 16 GB Mac Pro and macOS Sierra on the 64 GB model. Both are old operating systems, and compatibility depends on the exact application version and the seller’s installed configuration. Before ordering, check the software maker’s supported macOS versions, required security features, and any access needs such as current browsers or collaboration tools. If a project depends on recent software or ongoing operating-system support, I would look at a newer Mac instead of treating an older system as an easy upgrade.
Match Thunderbolt 2 and other ports to your setup
Both listings specify six Thunderbolt 2 ports and four USB 3.0 ports; the 64 GB listing also names HDMI 1.4 and dual Gigabit Ethernet. This can be handy for older displays, drives, and wired networks, but buyers should compare the actual connector and bandwidth requirements of their equipment. Newer Thunderbolt devices may need adapters, and adapters do not add the capabilities of a newer host port. With limited internal expansion, plan for external storage and confirm that essential peripherals can connect reliably.
Treat renewed condition and warranty as buying criteria
Renewed hardware can vary by seller and unit, so I would check the product condition description, included accessories, return window, and warranty terms before purchase. The 64 GB listing states a minimum 90-day refurbished warranty; the supplied information for the 16 GB model does not name a term. Ask what is covered and how a return or repair is handled. Also verify the exact model, installed operating system, memory configuration, and physical dimensions, particularly because the two listings provide different size details for machines described as the Late 2013 Mac Pro.
Set expectations for an older workstation
These computers share a quad-core Xeon and dual FirePro D300 graphics, so neither is a route to a modern CPU or GPU. Their compact design and workstation connections may fit a legacy studio or specialist environment, but the narrow internal upgrade options limit how far the system can be adapted. I would buy only after checking that the exact workload runs on the specified operating system and that the performance level is acceptable. For new creative work, long-term support, or demanding current applications, a newer desktop is a safer fit.
Frequently Asked Questions
Which renewed Mac Pro is the better choice between these two?
I rank the 64 GB Late 2013 model first because its memory capacity gives more room for larger projects and concurrent applications, and its listing specifies a minimum 90-day refurbished warranty. Both products share a quad-core Xeon, dual FirePro D300 graphics, and 512 GB storage, so the higher-memory configuration is the clearest practical advantage. The 16 GB model can still fit a lighter, well-defined legacy workload.
Are these Mac Pro desktops suitable for current software?
They should not be assumed to support current applications simply because they are Mac Pro workstations. The product details list OS X Yosemite for one and macOS Sierra for the other, and both have older Intel hardware. I would check the exact application’s supported operating systems and security requirements before buying. If current software support is a must, I would choose a newer Mac rather than relying on an older system.
Is 16 GB of memory enough for a renewed Mac Pro?
It can be enough for a modest workload that uses compatible older software and keeps memory demands limited. It offers much less headroom than the other listing’s 64 GB configuration, so large projects or several demanding applications may outgrow it. Since both have the same stated processor and graphics, memory is the main configuration difference to weigh against the work you plan to run.
Can I connect modern displays and external drives?
Both listings provide Thunderbolt 2 and USB 3.0, and the 64 GB configuration also lists HDMI 1.4. Some modern peripherals may work through compatible adapters, but the Mac Pro’s older ports do not become newer standards when an adapter is added. Before purchase, check each device’s connector, power needs, and required bandwidth, and confirm whether an adapter is needed for your display or storage setup.
What should I check before ordering a renewed Mac Pro?
I would verify the exact model and configuration, installed operating system, physical condition, included accessories, return terms, and warranty coverage. The 64 GB listing states a minimum 90-day refurbished warranty, while the supplied details for the 16 GB model do not specify a warranty duration. I would also confirm port compatibility and ask the seller to clarify the listed dimensions, since the product descriptions provide different measurements.
Conclusion
For a buyer who needs more memory for a compatible legacy workflow, I recommend the 64 GB Late 2013 Mac Pro, provided its old operating system and ports fit the intended setup and the warranty terms are acceptable. For someone running a lighter application set that works within 16 GB, the other renewed model offers the same broad processor, graphics, and storage profile in a compact listed form. I would skip both if current macOS support, modern connectivity, easy internal upgrades, or strong performance in recent demanding software is the main goal; these are older workstations best chosen for a specific reason, not as general-purpose modern desktops.
