I compared these two renewed Mac Pro desktops for buyers who need a compact Intel workstation and are comfortable weighing older hardware against a familiar tower-style setup. My best overall pick is the 64 GB model: it keeps the same quad-core Xeon and dual FirePro D300 graphics as the other option, but its larger memory capacity makes it better suited to heavier multitasking. The 16 GB model is the simpler fit for lighter workloads, with the same 512 GB PCIe flash storage and broad connection selection.

The main tradeoffs are not between processor speed or graphics, which are closely matched, but between memory headroom, operating-system age, and refurbishment details. Both are late-2013 designs with limited internal expansion, and their listed operating systems are old. I would treat either as a legacy workstation rather than a current Mac for demanding new software. Before choosing, check the seller’s condition, included accessories, return terms, and whether the installed operating system suits your applications.
Key Takeaways
- Choose the 64 GB model if you run several memory-hungry applications or keep large projects open; its processor and graphics are otherwise much like the 16 GB option.
- The 16 GB model still has 512 GB PCIe flash storage and dual FirePro D300 cards, so it can suit lighter workstation tasks without paying for memory capacity you may not use.
- Both computers use a 3.7 GHz quad-core Xeon E5 and dual AMD FirePro D300 graphics, so neither is a clear choice for buyers seeking a newer CPU or modern GPU.
- Operating-system versions differ: the 16 GB listing specifies OS X Yosemite, while the 64 GB listing specifies macOS Sierra; check software and security requirements before purchase.
- Neither offers easy internal expansion, and the 64 GB listing includes a minimum 90-day refurbished warranty while the 16 GB listing provides no warranty detail in the supplied specifications.

Apple Mac Pro (Late 2013), 3.7 GHz Quad-Core Xeon, 64 GB RAM, 512 GB SSD (Renewed)
This is my first choice of the two because 64 GB of ECC memory gives the late-2013 Mac Pro more room for concurrent applications and larger projects. Its 3.7 GHz quad-core Xeon E5-1620 v2, dual FirePro D300 cards, and 512 GB SSD match the central hardware profile of the 16 GB alternative. That makes memory—not a newer processor or a stronger listed graphics setup—the key reason to rank this model first.
For a buyer handling several professional applications at once, the extra memory can reduce the need to close programs or divide work into smaller sessions. The six Thunderbolt 2 ports, four USB 3.0 ports, HDMI 1.4, and dual Gigabit Ethernet also give it useful ways to connect displays, storage, and a wired network. Compared with the 16 GB option, it is the more capable configuration for memory-heavy use, though both remain limited by the same older platform and modest internal expandability.
The listing specifies macOS Sierra and a minimum 90-day refurbished warranty, plus accessories. Those details are useful, but they do not resolve whether the Mac can run the exact applications you need today; verify compatibility before buying. The supplied dimensions also differ from the other listing despite both naming the late-2013 ME253LL/A model, so I would confirm the actual unit’s measurements and condition with the seller. I would skip it if you need current-generation performance, modern graphics features, or a machine that is easy to upgrade internally.

Our verdict“I would choose this 64 GB configuration for legacy Mac workflows that benefit from memory headroom, provided its software and condition meet your needs.”
Apple Mac Pro Desktop Computer, 3.7 GHz Quad-Core Intel Xeon E5, 16 GB RAM, 512 GB SSD (Renewed)
This configuration keeps the main hardware familiar: the same 3.7 GHz quad-core Xeon E5 and dual FirePro D300 graphics found in the 64 GB model, alongside a 512 GB PCIe flash SSD. Its distinction is the 16 GB of ECC memory. That is enough to make sense for lighter office, media, or legacy professional work, but it leaves less room for large files and several demanding apps running together.
Compared with the 64 GB pick, this model does not offer a different processor or graphics system in the supplied specifications; the main sacrifice is memory capacity and stated refurbishment coverage. The listed six Thunderbolt 2 ports and four USB 3.0 ports remain useful for external storage and accessories, while the unusually compact 9.9-by-6.6-inch body may suit a desk where a conventional tower would be awkward. Its PCIe flash storage is a welcome feature, though 512 GB may fill quickly if you keep project media locally.
The biggest caution is its specified OS X Yosemite operating system, an older release that may not support the apps or security expectations of a present-day setup. I would verify whether the seller can confirm the installed software, unit condition, included accessories, and any warranty or return terms; none are detailed in the supplied product information. For buyers who need the memory headroom offered by the other listing, the 64 GB model is the stronger choice. I would pick this one only when the workload is modest and the specific legacy software fit is clear.
Pros:- 3.7 GHz quad-core Xeon E5 with dual FirePro D300 graphics
- 512 GB PCIe flash SSD
- Six Thunderbolt 2 and four USB 3.0 ports
- Compact 9.9-inch-tall chassis
Cons:- 16 GB memory is substantially lower than the 64 GB alternative
- OS X Yosemite is an old listed operating system
- Supplied details do not state a refurbishment warranty
Best for: Buyers seeking a compact renewed Mac Pro for lighter legacy tasks, external-device connectivity, or a familiar Intel Mac setup that does not demand extensive memory.
Not ideal for: Users running memory-intensive creative projects, buyers who need a recent operating system, or anyone requiring confirmed warranty coverage and upgrade flexibility.

Our verdict“I would select the 16 GB version for lighter legacy work where its compact size and ports matter more than memory headroom.”
How We Picked
I ranked these renewed Mac Pro desktops around the decisions that matter for a used workstation: memory capacity, core hardware, connectivity, operating-system compatibility, and refurbishment information. Since both listings describe the same 3.7 GHz quad-core Xeon E5 platform, dual FirePro D300 graphics, and 512 GB of storage, I did not treat either as a faster-generation machine. Instead, I gave the 64 GB version the overall lead because more memory offers practical breathing room for multitasking and larger working files.
I also separated a buyer’s likely workload from the headline specifications. A compact chassis and several Thunderbolt 2 ports can help someone building around external drives or displays, but they do not make a 2013 system equivalent to a modern workstation. The stated operating systems are dated, and the supplied information does not confirm current application support, upgrade paths, battery-like wear items, or the condition of each renewed unit. I therefore treat those as purchase checks, not assumed benefits. The 16 GB model ranks as the lighter-workload alternative; the 64 GB model ranks higher for capacity and has a stated minimum 90-day warranty.
| 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 choose between these renewed Mac Pro desktops by matching the machine’s limits to a specific legacy workflow, not by treating the shared model name as a sign of current performance.Memory matters more than the shared processor here
Both listings name a 3.7 GHz quad-core Xeon E5 and dual FirePro D300 graphics, so neither has a meaningful listed advantage in those headline parts. The 64 GB configuration instead gives you four times the memory of the 16 GB model. That is the more useful distinction if you keep multiple applications open, work with larger files, or use software that benefits from extra RAM. For lighter use, 16 GB may be sufficient, but I would not choose it on the assumption that its CPU or graphics are newer.
Check software compatibility before buying
The listings specify OS X Yosemite and macOS Sierra, both old releases. That matters more than a minor port difference if you rely on current creative tools, cloud services, security updates, or newer peripherals. I would check each required application’s supported macOS versions and ask the seller which operating system is installed on the particular renewed unit. Do not assume an upgrade is available or straightforward based only on the product title.
Plan around ports and limited internal expansion
These compact Mac Pros offer multiple Thunderbolt 2 and USB 3.0 connections, and the 64 GB listing also names HDMI and dual Gigabit Ethernet. That can help buyers who already use external drives, displays, or wired networks. The tradeoff is limited internal expansion: plan your storage and peripherals before purchase, and check compatibility for any Thunderbolt adapters or displays you need. If you want to add modern components inside a tower, neither option is a natural fit.
Verify the renewed unit, not just the model
Renewed condition can vary, so I would ask about cosmetic wear, included power cable and accessories, testing, return terms, and the warranty that applies to the exact listing. The 64 GB product states a minimum 90-day refurbished warranty; the supplied details for the 16 GB product do not specify one. Also resolve the differing dimensions listed for the 64 GB unit and the other model entry, since the product names identify the same late-2013 generation. Clear seller answers can matter as much as the configuration when buying older hardware.
Frequently Asked Questions
Which renewed Mac Pro is the better choice for multitasking?
I would choose the 64 GB model for multitasking because it has much more memory than the 16 GB alternative. Both listings describe the same quad-core Xeon and dual FirePro D300 graphics, so the extra RAM is the clear configuration advantage. The right choice still depends on whether your applications support the listed older macOS release.
Are these two Mac Pro desktops from different generations?
The supplied information identifies both as late-2013 Mac Pro hardware, including the ME253LL/A model reference. Their central processor and graphics details are also closely matched. The main differences in these listings are memory capacity, stated operating system, refurbishment details, and some listed physical specifications—not a newer generation of processor.
Can I use either computer for current professional software?
That depends on the software, and I would not assume compatibility from the product name alone. The 16 GB listing specifies OS X Yosemite, while the 64 GB listing specifies macOS Sierra; both are old versions. Check the exact operating-system requirements for each application and confirm the installed system and upgrade options with the seller before placing an order.
Which model is better for a modest legacy workstation?
The 16 GB model can be the more suitable match when your applications are light, your files are manageable, and you value the compact chassis and external connections. It still includes the listed Xeon processor, dual FirePro graphics, and 512 GB PCIe flash storage. I would choose the 64 GB model instead if you regularly run memory-heavy work or want more capacity for future multitasking.
What should I check about refurbishment before buying?
I would confirm the condition grade, included accessories, return policy, warranty coverage, and whether the seller has tested the storage, ports, and graphics. The 64 GB listing specifies a minimum 90-day refurbished warranty; the supplied information for the 16 GB listing does not state one. Ask the seller to verify the exact unit and its operating system, especially because these are older computers and the listings contain differing physical details.
Conclusion
For buyers who need more memory for multitasking or larger legacy projects, I recommend the 64 GB renewed Mac Pro, subject to confirming software support and the unit’s condition. For a lighter workload where a compact chassis, 512 GB PCIe storage, and Thunderbolt 2 connections matter more than extra RAM, I would choose the 16 GB model—but only after checking warranty and return details. If your priority is current macOS support, modern graphics, or easy internal upgrades, I would skip both and look for a newer Mac instead.
