AMD FirePro W5000 vs NVIDIA GeForce GTX 675MX Comparison

AMD FirePro W5000 and NVIDIA GeForce GTX 675MX are both 28 nm graphics products from 2012, but they target very different physical and performance environments. The FirePro W5000 is a single-slot workstation card with a 75 W power envelope, while the GTX 675MX is a mobile MXM module with a 100 W rating. The recorded benchmark data shows a clear split: the NVIDIA part wins the only shared test, but the AMD part holds a higher percentile ranking and a much stronger average score when all of its recorded results are considered.

Where Each One Wins

The NVIDIA GeForce GTX 675MX takes the only direct head-to-head benchmark victory. In the Geekbench OpenCL test, the GTX 675MX scores 10,723 against 9,803 for the FirePro W5000, a delta of 8.6% in NVIDIA’s favor. That is the sole benchmark shared by both products in the database, so any use-case split must start there: for OpenCL compute workloads as measured by Geekbench, the GTX 675MX is the faster part.

The AMD FirePro W5000 wins on overall standing. Its average benchmark score is 9,803, which places it in the 47th percentile of all GPUs. The GTX 675MX has an average score of 8,427 (the average of its OpenCL 10,723 and Metal 6,131 results) and sits in the 43rd percentile. So while the NVIDIA part wins the one direct comparison, the AMD part is ranked higher across the entire GPU population. The FirePro W5000 also has a much tighter benchmark profile: it has only one recorded result, while the GTX 675MX has two, and the GTX 675MX’s Metal score of 6,131 is substantially lower than its OpenCL score.

The use case split is therefore twofold. If the workload is specifically OpenCL compute, the GTX 675MX is the winner. If the metric is overall GPU percentile or consistency across heterogeneous workloads, the FirePro W5000 comes out ahead. The FirePro W5000’s nearest rivals in the database are all NVIDIA parts with scores between 9,724 and 9,846, meaning it sits in a very tight cluster; the GTX 675MX’s nearest rivals are a mix of AMD and NVIDIA mobile and desktop parts with scores between 8,325 and 8,462, a lower and broader cluster.

Head-to-Head Benchmarks

The database records exactly one head-to-head benchmark between these two parts: Geekbench OpenCL. The NVIDIA GeForce GTX 675MX scores 10,723, and the AMD FirePro W5000 scores 9,803. The delta is 8.6% in favor of NVIDIA. This is a substantial margin in a compute-oriented test, and it is the only direct measurement available, so it carries the full weight of the head-to-head comparison.

Context from the rivals list helps interpret that margin. The FirePro W5000’s nearest rivals include the NVIDIA GeForce GTX 1070 at 9,780, the NVIDIA Quadro M2000M at 9,832, the NVIDIA Quadro 6000 at 9,846, and the NVIDIA Tesla M10 at 9,724. The FirePro W5000’s 9,803 sits almost exactly in the middle of that group, within 0.4% of the Quadro 6000 and 0.2% of the GTX 1070. The GTX 675MX’s 10,723 OpenCL score is therefore not just ahead of the FirePro W5000; it is also ahead of every single one of the FirePro W5000’s nearest rivals. None of those NVIDIA parts break 9,850.

But the GTX 675MX’s average is dragged down by its other recorded benchmark. Its Geekbench Metal score is 6,131, which is 42.8% lower than its own OpenCL score. That Metal result is what brings the GTX 675MX average down to 8,427 and its percentile down to 43. The FirePro W5000 has no Metal result, only OpenCL, so its average and percentile are both derived from the same 9,803 score.

The texture and pixel rate data add another layer. The GTX 675MX has a texture rate of 52.32 GTexel/s versus 39.60 GTexel/s for the FirePro W5000, a 32% advantage for NVIDIA. But the FirePro W5000 has a pixel rate of 26.40 GPixel/s versus 13.08 GPixel/s for the GTX 675MX, a 102% advantage for AMD. The two cards are not simply faster or slower than each other; they win in different rasterization stages.

Specification Differences

The two products differ in nearly every major specification category. The FirePro W5000 is a desktop workstation card with a single-slot design, 183 mm length, 111 mm height, and no power connectors. The GTX 675MX is an MXM-B (3.0) mobile module with no listed dimensions and also no power connectors. The FirePro W5000 specifies a suggested power supply of 250 W, while the GTX 675MX lists none.

Memory is similar in capacity and type but differs in speed. Both have 2 GB of GDDR5 on a 256-bit bus. The FirePro W5000 memory clock is 800 MHz with 3.2 Gbps effective, yielding 102.4 GB/s of bandwidth. The GTX 675MX memory clock is 900 MHz with 3.6 Gbps effective, yielding 115.2 GB/s. The NVIDIA part has a 12.5% bandwidth advantage.

The compute unit counts differ substantially. The FirePro W5000 has 768 shading units, 48 TMUs, and 32 ROPs. The GTX 675MX has 960 shading units, 80 TMUs, and 32 ROPs. NVIDIA has 25% more shading units and 67% more TMUs, while ROP count is identical at 32.

Outputs and API support also differ. The FirePro W5000 provides 1x DVI and 2x DisplayPort 1.2 outputs. The GTX 675MX’s display outputs are listed as portable device dependent. The FirePro W5000 supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The GTX 675MX supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. The NVIDIA part has a slightly newer Vulkan version, while the AMD part has a slightly higher DirectX feature level.

The FirePro W5000 has a launch MSRP of 599 USD. The GTX 675MX has no recorded launch MSRP.

Architecture Differences

The two chips come from different architectural families. The FirePro W5000 is built on AMD’s GCN 1.0 architecture, using the Pitcairn chip, and belongs to the FirePro GCN (Wx000) generation. The GTX 675MX is built on NVIDIA’s Kepler architecture, using the GK104 chip, and belongs to the GeForce 600M generation. Both are fabricated by TSMC on a 28 nm process.

The transistor and die size numbers favor the NVIDIA chip. The GTX 675MX has 3,540 million transistors on a 294 mm² die, giving a transistor density of 12.0 million per mm². The FirePro W5000 has 2,800 million transistors on a 212 mm² die, giving a density of 13.2 million per mm². So the AMD chip is denser per square millimeter, but the NVIDIA chip is larger overall and packs 26% more transistors.

The FP32 compute figures are nearly identical despite the architectural differences. The FirePro W5000 delivers 1,267.2 GFLOPS, and the GTX 675MX delivers 1,255.7 GFLOPS. That is a difference of less than 1%, making the two parts essentially equal in raw single-precision throughput. The measured OpenCL score, however, favors NVIDIA by 8.6%, suggesting that efficiency and driver behavior matter more than the theoretical FP32 ceiling in this test.

Neither part has ray tracing cores or tensor cores. Both have null values for those fields in the database. Neither lists a base or boost clock, only memory clocks. The FirePro W5000’s predecessor is FirePro Terascale and its successor is Radeon Pro Polaris. The GTX 675MX’s predecessor is GeForce 500M and its successor is GeForce 700M. Both products are marked as end-of-life. The FirePro W5000 was released on 2012-08-06, and the GTX 675MX on 2012-09-30, about two months apart.

The Verdict

The data supports a split decision based on workload type. For OpenCL compute performance, the NVIDIA GeForce GTX 675MX is the clear choice. Its 10,723 OpenCL score beats the FirePro W5000’s 9,803 by 8.6%, and it also beats every rival listed near the FirePro W5000, none of which exceed 9,850. The GTX 675MX also has higher texture rate (52.32 GTexel/s vs 39.60 GTexel/s), higher memory bandwidth (115.2 GB/s vs 102.4 GB/s), more shading units (960 vs 768), and more TMUs (80 vs 48). If the target workload is compute-heavy and measured by OpenCL, the GTX 675MX wins on every relevant metric.

For overall GPU standing and consistency, the AMD FirePro W5000 is the better-ranked part. Its 47th percentile placement beats the GTX 675MX’s 43rd, and its average score of 9,803 is 16.3% higher than the GTX 675MX’s 8,427. The GTX 675MX is dragged down by its Metal score of 6,131, which is 42.8% below its own OpenCL result. The FirePro W5000 has no such split; its single recorded score is its average, and that score sits within 0.4% of the NVIDIA Quadro 6000 and 0.2% of the GeForce GTX 1070.

The pixel rate difference is also decisive for certain workloads. The FirePro W5000 delivers 26.40 GPixel/s, exactly double the GTX 675MX’s 13.08 GPixel/s. This makes the AMD card the stronger choice for fill-rate-bound scenarios, despite its lower texture throughput. The FirePro W5000 also has a lower power envelope at 75 W versus 100 W, a smaller die at 212 mm² versus 294 mm², and a display output configuration that includes two DisplayPort 1.2 connections, which suits fixed workstation setups. The GTX 675MX is a mobile module with portable device dependent outputs, so it is not a drop-in replacement for a desktop workstation card.

The verdict is therefore conditional. Buyers with OpenCL compute workloads should choose the GTX 675MX. Buyers who value overall percentile ranking, pixel fill rate, or a fixed desktop workstation form factor should choose the FirePro W5000. The two cards are near-equal in FP32 throughput (1,267.2 GFLOPS vs 1,255.7 GFLOPS), so the deciding factors are the OpenCL delta, the Metal result, and the architectural feature split. The GTX 675MX wins the one head-to-head test, but the FirePro W5000 wins the broader comparison.
