AMD FirePro W5000 vs NVIDIA GeForce GTX 465 Comparison

The AMD FirePro W5000 and NVIDIA GeForce GTX 465 occupy adjacent positions in the benchmark database, with the FirePro scoring 9803 and the GTX 465 scoring 9294 in Geekbench OpenCL. The 5.5% delta between them places the FirePro in the 47th percentile of all GPUs, while the GTX 465 sits at the 46th percentile. These are professional and consumer cards from different eras, and the data reveals a clear but narrow performance gap with significant architectural consequences.

Where Each One Wins

The AMD FirePro W5000 wins the only head-to-head benchmark recorded in the database, the Geekbench OpenCL test, by a margin of 5.5%. This is a single test, but it represents the entire comparative dataset, so the FirePro holds a 1-0 win record. The FirePro’s score of 9803 places it within a tight cluster of rivals: it is 0.2% ahead of the NVIDIA GeForce GTX 1070 (9780), 0.3% behind the NVIDIA Quadro M2000M (9832), and 0.4% behind the NVIDIA Quadro 6000 (9846). The GTX 465’s score of 9294, by contrast, places it 0.1% ahead of the NVIDIA GeForce GTX 850M (9302) and 0.2% ahead of the AMD Radeon R7 M380 (9313), but 0.2% behind the NVIDIA GeForce GTX 960 (9273) is actually a lead of 0.2% for the 465, and it is 0.8% ahead of the AMD Radeon Vega 8 (9221).

The FirePro wins the compute workload outright, but the GTX 465 is not without merit. Its nearest-rival cluster is populated by mobile and entry-level desktop parts, whereas the FirePro’s cluster includes the high-end GTX 1070 and professional Quadro cards. This suggests the FirePro’s compute performance is competitive with much newer hardware, while the GTX 465’s performance aligns with older or lower-tier offerings. For OpenCL compute tasks, the FirePro is the clear pick; for any workload not represented in this single benchmark, the data does not provide a basis for comparison.

Architecture Differences

The architectural gap between these two cards is substantial. The AMD FirePro W5000 uses the Pitcairn chip built on GCN 1.0 architecture, fabricated by TSMC on a 28 nm process. It packs 2,800 million transistors into a 212 mm² die, yielding a transistor density of 13.2M per mm². The NVIDIA GeForce GTX 465 uses the GF100 chip on the Fermi architecture, also from TSMC but on a 40 nm process. It contains 3,100 million transistors on a much larger 529 mm² die, with a density of only 5.9M per mm². The FirePro’s newer process node allows it to pack more transistors per area and run at a dramatically lower power envelope.

Compute resources differ sharply. The FirePro has 768 shading units, 48 texture mapping units, and 32 ROPs. The GTX 465 has 352 shading units, 44 TMUs, and 32 ROPs. This means the FirePro has more than double the shader count and slightly more TMUs, while ROP counts are identical. The FirePro’s pixel rate is 26.40 GPixel/s and texture rate is 39.60 GTexel/s, versus 13.38 GPixel/s and 26.75 GTexel/s for the GTX 465. FP32 throughput is 1,267.2 GFLOPS for the FirePro versus 855.4 GFLOPS for the GTX 465. Neither card has RT or tensor cores.

Memory configurations are similar in bus width but differ in capacity. Both use GDDR5 with a 256-bit bus. The FirePro has 2 GB while the GTX 465 has 1024 MB. Memory bandwidth is nearly identical: 102.4 GB/s for the FirePro and 102.7 GB/s for the GTX 465, with memory clocks of 3.2 Gbps effective for both. API support also differs: the FirePro supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170, while the GTX 465 supports DirectX 12 (11_0) and OpenGL 4.6 but has no Vulkan support listed.

FAQ

Q: Which card has higher raw compute throughput in FP32?

A: The AMD FirePro W5000 delivers 1,267.2 GFLOPS, which is 48% higher than the NVIDIA GeForce GTX 465’s 855.4 GFLOPS. This aligns with the FirePro’s 5.5% advantage in the Geekbench OpenCL benchmark.

Q: Do both cards have the same memory bus width?

A: Yes, both use a 256-bit bus with GDDR5 memory. The FirePro has 2 GB of memory while the GTX 465 has 1024 MB, and bandwidth is nearly identical at 102.4 GB/s versus 102.7 GB/s.

Q: What is the transistor density difference between the two chips?

A: The FirePro’s Pitcairn chip has a density of 13.2M transistors per mm² on a 28 nm process, while the GTX 465’s GF100 chip has 5.9M per mm² on a 40 nm process.

A: The FirePro scores 9803, which is 0.2% ahead of the GeForce GTX 1070 (9780) and 0.8% ahead of the Tesla M10 (9724), but 0.3% behind the Quadro M2000M (9832) and 0.4% behind the Quadro 6000 (9846).

Q: What is the power connector requirement for each card?

A: The FirePro W5000 requires no power connectors and has a TDP of 75 W, with a suggested PSU of 250 W. The GTX 465 requires two 6-pin connectors, has a TDP of 200 W, and suggests a 550 W PSU.

Specification Differences

The two cards differ in nearly every major specification category. The process node is 28 nm for the FirePro versus 40 nm for the GTX 465, and transistor counts are 2,800 million versus 3,100 million, with die sizes of 212 mm² versus 529 mm². Transistor density is 13.2M per mm² versus 5.9M per mm². The FirePro has 768 shading units, 48 TMUs, and 32 ROPs; the GTX 465 has 352 shading units, 44 TMUs, and 32 ROPs. Pixel rate is 26.40 GPixel/s versus 13.38 GPixel/s, and texture rate is 39.60 GTexel/s versus 26.75 GTexel/s. FP32 performance is 1,267.2 GFLOPS versus 855.4 GFLOPS.

Memory capacity is 2 GB versus 1024 MB, with the same 256-bit bus and nearly identical bandwidth (102.4 GB/s versus 102.7 GB/s). TDP is 75 W versus 200 W, slot width is single-slot versus dual-slot, and power connectors are none versus 2x 6-pin. Suggested PSU is 250 W versus 550 W. Bus interface is PCIe 3.0 x16 versus PCIe 2.0 x16. Display outputs are 1x DVI and 2x DisplayPort 1.2 versus 2x DVI and 1x mini-HDMI 1.3a. DirectX support is 12 (11_1) versus 12 (11_0), and Vulkan is 1.2.170 versus none. Physical dimensions are 183 mm length versus 241 mm length.

Head-to-Head Benchmarks

The only recorded head-to-head benchmark is Geekbench OpenCL, where the AMD FirePro W5000 scores 9803 against the NVIDIA GeForce GTX 465’s 9294. The FirePro wins by 5.5%, which is a decisive margin given the narrow spread of scores in each card’s rival cluster. To contextualize this, the FirePro’s 5.5% lead is larger than the delta between the GTX 465 and its nearest rival, the GeForce GTX 850M, which is only 0.1%. The FirePro’s advantage is also larger than the gap between the FirePro and the Quadro 6000, which sits just 0.4% ahead of it.

The absolute score difference is 509 points. In percentile terms, the FirePro sits at 47th versus 46th for the GTX 465, which is a one-percentile shift. However, the rival clusters tell a different story. The FirePro’s score places it alongside the GeForce GTX 1070 (9780), a much newer and higher-tier card, while the GTX 465’s score places it alongside mobile parts like the GeForce GTX 850M (9302) and AMD Radeon R7 M380 (9313). The FirePro’s FP32 throughput of 1,267.2 GFLOPS versus 855.4 GFLOPS for the GTX 465 explains part of this gap, as does the 768-to-352 shading unit advantage. The GTX 465’s 32 ROPs match the FirePro’s 32 ROPs, but the FirePro’s 48 TMUs versus 44 TMUs and higher pixel rate (26.40 versus 13.38 GPixel/s) give it a clear edge in fill-rate-bound tasks.

The Verdict

The data points to the AMD FirePro W5000 as the stronger card in the one benchmark recorded. It wins the Geekbench OpenCL test by 5.5%, has 48% higher FP32 throughput, more than double the shading units, and a higher pixel rate. Its 2 GB memory capacity is double the GTX 465’s 1024 MB, and it supports Vulkan while the GTX 465 does not. The FirePro also achieves this with a 75 W TDP versus 200 W, no power connectors versus two 6-pin connectors, and a single-slot design versus dual-slot. The GTX 465’s only advantages in the specification list are a slightly higher memory bandwidth (102.7 GB/s versus 102.4 GB/s) and a higher transistor count (3,100 million versus 2,800 million), but the latter is offset by a much larger die and lower density.

For users choosing between these two for OpenCL compute workloads, the FirePro W5000 is the clear winner based on the benchmark score and architecture efficiency. Its nearest-rival cluster includes the GeForce GTX 1070 and Quadro 6000, indicating it competes at a higher performance tier than the GTX 465, whose rivals are mobile and entry-level parts. The GTX 465, with its older Fermi architecture and 40 nm process, offers no benchmark win in this dataset and trails in every performance-relevant specification except memory bandwidth by a negligible margin. The FirePro’s lower power draw, smaller physical footprint, and more modern feature set (PCIe 3.0, DisplayPort 1.2, Vulkan) make it the more future-proof option. The GTX 465 may have been competitive at its 2010 release, but against this 2012 FirePro, the data shows a consistent, if modest, advantage for the AMD card.
