AMD FirePro W5130M vs NVIDIA GeForce GT 645M Comparison

Head-to-Head Benchmarks

The only directly comparable benchmark recorded in the database is Geekbench OpenCL, and the results are decisive. The AMD FirePro W5130M scores 4904 points, while the NVIDIA GeForce GT 645M scores 2680 points. This translates to an 83% advantage for the AMD part, a massive gap in raw compute throughput. The FirePro W5130M is not merely faster, it is nearly twice as fast in this workload.

Context from the nearest rival lists reinforces this dominance. The FirePro W5130M sits at the 29th percentile of all GPUs in the database, while the GT 645M sits at the 26th percentile. The FirePro W5130M outperforms the NVIDIA GeForce GTS 450 by 0.2% and the NVIDIA GeForce RTX 5060 Ti 8 GB by 0.1%, while trailing the AMD Radeon R7 M265 and R7 M360 by 0.5% each. This places the FirePro W5130M in a tight cluster where small percentage swings separate functionally equivalent results. The GT 645M, by contrast, is 0.5% ahead of the NVIDIA GeForce 930M, 1.2% ahead of the Intel Iris Pro Graphics 5200, and 1.8% ahead of the NVIDIA GeForce RTX 4070 GDDR6, while trailing the AMD Radeon R7 M260 by 1.9%. These rival deltas show that both cards are mid-pack performers, but the head-to-head OpenCL result shows a clear stratification between them.

The GT 645M does have additional benchmark entries in the database, including a Geekbench Metal score of 5679 and a Geekbench Vulkan score of 4875. However, these tests were not run on the FirePro W5130M, so no direct comparison is possible. The FirePro W5130M has only the single OpenCL entry, which is also its average benchmark score. The GT 645M's average across all recorded benchmarks is 4411, which is lower than its Metal and Vulkan scores, indicating that the OpenCL result drags its average down substantially. Even taking the GT 645M's best recorded score of 5679 in Metal, that result cannot be compared to the FirePro W5130M because the AMD part has no Metal result. The only apples-to-apples measurement favors the FirePro W5130M by a wide margin.

The Verdict

The data points to a single conclusion for compute-oriented workloads: the AMD FirePro W5130M is the superior part. Its 83% lead in Geekbench OpenCL is not a marginal edge, it is a generational gap in raw throughput. The FirePro W5130M's fp32 performance of 947.2 GFLOPS against the GT 645M's 599.0 GFLOPS explains the benchmark outcome. The FirePro W5130M also delivers higher pixel rate (14.80 GPixel/s vs 6.240 GPixel/s) and higher texture rate (29.60 GTexel/s vs 24.96 GTexel/s). For anyone running OpenCL-accelerated applications, the choice is unambiguous.

The GT 645M does have a counterargument in the form of its Vulkan score of 4875, which nearly matches the FirePro W5130M's OpenCL score. If a user's workload relies on Vulkan, the GT 645M may be sufficient. The Metal score of 5679 is also notable, but only on platforms where Metal is available, and the FirePro W5130M was not tested in that API. The GT 645M also draws a stated TDP of 32 W, while the FirePro W5130M's TDP is not recorded in the database. For power-constrained mobile designs, the GT 645M's modest 32 W rating is a documented advantage, though the FirePro W5130M's power draw is simply unknown here.

The percentile rankings tell a similar story. The FirePro W5130M at the 29th percentile sits above the GT 645M at the 26th percentile. Neither card is a top-tier performer, but the FirePro W5130M is consistently ahead in every directly comparable metric. The GT 645M is a Kepler-generation part from 2012, while the FirePro W5130M is a GCN 1.0 part from 2015. Three years of architectural progress, combined with faster memory, explain the performance gap.

Specification Differences

The two GPUs differ in nearly every meaningful specification. The FirePro W5130M uses a 128-bit memory bus with 2 GB of GDDR5 memory, while the GT 645M uses the same 128-bit bus but with 2 GB of DDR3 memory. The memory clock is listed at 1000 MHz with 4 Gbps effective for the FirePro W5130M, versus 900 MHz with 1800 Mbps effective for the GT 645M. This yields a memory bandwidth of 64.00 GB/s for the AMD part, more than double the GT 645M's 28.80 GB/s.

The compute resources also favor the FirePro W5130M. It packs 512 shading units, 32 TMUs, and 16 ROPs, while the GT 645M has 384 shading units, 32 TMUs, and 16 ROPs. Clock speeds differ as well: the FirePro W5130M runs at 900 MHz base and 925 MHz boost, while the GT 645M runs at 709 MHz base and 780 MHz boost. The resulting throughput figures are 947.2 GFLOPS fp32 for the FirePro W5130M versus 599.0 GFLOPS fp32 for the GT 645M. Pixel rate is 14.80 GPixel/s versus 6.240 GPixel/s, and texture rate is 29.60 GTexel/s versus 24.96 GTexel/s.

The GT 645M has a recorded TDP of 32 W and is classified as an IGP with no power connectors and display outputs that are portable device dependent. The FirePro W5130M has no TDP, slot width, power connector, or display output data in the database. Both use a PCIe 3.0 x16 bus interface. The GT 645M supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175, while the FirePro W5130M supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170.

Architecture Differences

The FirePro W5130M is built on the GCN 1.0 architecture using the Tropo chip, while the GT 645M uses the Kepler architecture with the GK107 chip. Both are fabricated on a 28 nm process at TSMC, but the FirePro W5130M packs 1,500 million transistors on a 123 mm² die, giving a transistor density of 12.2M per mm². The GT 645M has 1,270 million transistors on a 118 mm² die, yielding 10.8M per mm². The FirePro W5130M is therefore both larger in absolute transistor count and denser per square millimeter.

The FirePro W5130M belongs to the FirePro Mobile (Wx100M) generation, with the FirePro Mobility as its predecessor and Radeon Pro Mobile as its successor. The GT 645M belongs to the GeForce 600M generation, with the GeForce 500M as its predecessor and GeForce 700M as its successor. The FirePro W5130M was released in 2015, while the GT 645M was released in 2012, a three-year gap that aligns with the architectural generational difference.

Both parts are end-of-life products. Neither has ray tracing cores or tensor cores. The FirePro W5130M has a higher DirectX feature level (11_1 vs 11_0) and a slightly older Vulkan version (1.2.170 vs 1.2.175). The fundamental architectural distinction is GCN 1.0's design for compute throughput versus Kepler's design for power efficiency. The benchmark data reflects that: the FirePro W5130M delivers substantially higher GFLOPS, pixel rate, and memory bandwidth, while the GT 645M carries a documented 32 W TDP. The FirePro W5130M's power consumption is not recorded, so the efficiency trade-off cannot be quantified. What is clear is that the FirePro W5130M was built to compute, and the OpenCL results confirm it.
