NVIDIA GeForce GTX 580M vs NVIDIA GeForce GTX 750 Comparison

Head-to-Head Benchmarks

The only directly comparable benchmark in the database is Geekbench OpenCL, and the result is decisive. The NVIDIA GeForce GTX 750 scores 9315, while the NVIDIA GeForce GTX 580M scores 6389. That is a 45.8% advantage for the GTX 750, a substantial margin that places the two cards in different performance tiers despite their similar naming.

The GTX 750 also has other benchmark results recorded: Geekbench Vulkan at 8078 and Geekbench Metal at 4274. The GTX 580M has no corresponding results for those workloads, so the cross-platform comparison is limited to OpenCL alone. Still, the OpenCL gap is large enough to establish a clear hierarchy. The GTX 750's average benchmark score across all recorded tests is 7222, while the GTX 580M's average is 6389, a difference that reflects not just the head-to-head result but also the broader benchmark footprint of the newer card.

Context from the nearest rivals reinforces the picture. The GTX 750 sits at the 40th percentile of all GPUs in the database, with an average score of 7222. Its closest competitors are the AMD Radeon Vega 8 Mobile at 7203 (0.3% behind), the NVIDIA GeForce GTX 560 SE at 7171 (0.7% behind), and the Intel Iris Pro Graphics P580 at 7170 (0.7% behind). Interestingly, the NVIDIA GeForce GTX 970 appears in the rival list with an average score of 7157, 0.9% behind the GTX 750, which suggests the GTX 750's benchmark standing is competitive with parts that historically occupied higher market positions.

The GTX 580M, by contrast, sits at the 37th percentile. Its nearest rival is the NVIDIA GeForce GTX 460 SE, which matches it exactly at 6389 with a 0% delta. The AMD Radeon Pro WX 4100 is 0.9% behind at 6330, and the AMD Radeon R7 M350 is 1% behind at 6327. The most unusual entry in the GTX 580M's rival list is the NVIDIA RTX PRO 5000 72 GB Blackwell, which scores 6407, a 0.3% margin over the GTX 580M. That a modern workstation GPU barely edges out a 2011 mobile part in this particular benchmark says more about the benchmark's workload characteristics than about the GTX 580M's competitiveness, but it does highlight that the GTX 580M's recorded performance is modest by current database standards.

Architecture Differences

The architectural gap between these two GPUs is wide, and it explains much of the benchmark delta. The GTX 750 is built on the Maxwell architecture using the GM107 chip, fabricated on a 28 nm process at TSMC. The GTX 580M uses the Fermi 2.0 architecture with the GF114 chip, also from TSMC, but on a 40 nm process. The node difference is significant: 28 nm versus 40 nm means the GTX 750 packs its transistors much more densely, at 12.6 million per square millimeter versus 5.9 million for the GTX 580M.

Transistor counts are similar, with the GTX 750 at 1,870 million and the GTX 580M at 1,950 million, but the die sizes tell a different story. The GTX 750's die is 148 mm², while the GTX 580M's die is 332 mm². That is a dramatic difference in physical footprint for nearly the same transistor budget, which is a direct consequence of the process node advantage. The Maxwell chip achieves comparable transistor density on a much smaller slice of silicon, which has downstream effects on power draw and thermal behavior.

The core configurations also diverge. The GTX 750 has 512 shading units, 32 texture mapping units, and 16 raster output pipelines. The GTX 580M has 384 shading units, 64 TMUs, and 32 ROPs. The GTX 580M has twice the texture units and twice the ROPs, which suggests it was designed with fill-rate-heavy workloads in mind, but its shading unit count is 25% lower than the GTX 750's. The pixel rate reflects this: the GTX 750 outputs 17.36 GPixel/s, while the GTX 580M manages 9.92 GPixel/s. The texture rate flips the other way: the GTX 580M achieves 39.68 GTexel/s versus 34.72 GTexel/s for the GTX 750.

Memory subsystems also differ substantially. The GTX 750 has 1024 MB of GDDR5 on a 128-bit bus, with 80.19 GB/s of bandwidth. The GTX 580M has 2 GB of GDDR5 on a 256-bit bus, delivering 96.00 GB/s. The GTX 580M has double the memory capacity and a wider bus, yielding 20% more bandwidth, but its memory clock is lower at 750 MHz (3 Gbps effective) versus 1253 MHz (5 Gbps effective) for the GTX 750. The wider bus compensates for the lower clock, but the GTX 750's faster memory clock shows how process improvements allowed higher memory speeds in a smaller package.

Power consumption is another major divider. The GTX 750 has a TDP of 55 W and requires no power connectors, with a suggested PSU of 250 W. The GTX 580M has a TDP of 100 W and also lists no power connectors, but it uses an MXM module form factor, which changes how power is delivered. The GTX 750 is a single-slot PCIe 3.0 x16 card, while the GTX 580M uses an MXM-B (3.0) interface designed for laptops. The form factor difference is fundamental: one is a desktop expansion card, the other is a mobile module.

Where Each One Wins

The GTX 750 wins in raw compute throughput. Its FP32 performance is 1,111.0 GFLOPS versus 952.3 GFLOPS for the GTX 580M, a 16.7% advantage in theoretical floating-point capability. That aligns with the OpenCL benchmark result, where the GTX 750 leads by 45.8%. The shading unit advantage, 512 versus 384, gives the GTX 750 more parallel compute lanes, and the newer Maxwell architecture extracts more efficiency from each unit.

The GTX 580M wins in memory capacity and texture throughput. Its 2 GB frame buffer is double the GTX 750's 1 GB, and its 96.00 GB/s bandwidth exceeds the GTX 750's 80.19 GB/s. The texture rate of 39.68 GTexel/s is also higher than the GTX 750's 34.72 GTexel/s, and the ROP count of 32 versus 16 suggests the GTX 580M could handle certain fill-rate-bound scenarios better, despite its lower pixel rate. The pixel rate discrepancy, 9.92 GPixel/s versus 17.36 GPixel/s, is curious: the GTX 580M has more ROPs but delivers fewer pixels per second, which points to clock speed limitations. The GTX 750 runs at 1020 MHz base and 1085 MHz boost, while the GTX 580M has no recorded base or boost clocks in the database, so a direct clock comparison is not possible.

For real-world use, the GTX 750 is the stronger choice for compute-oriented tasks like OpenCL workloads, given its benchmark lead and higher FP32 throughput. The GTX 580M's larger memory pool and wider bus could be relevant for applications that need more than 1 GB of video memory, but its lower compute scores and higher power draw limit its appeal. The GTX 750's 55 W TDP versus the GTX 580M's 100 W TDP also means the desktop card is far more efficient per watt, a significant factor for system builders.

The GTX 580M's advantage in texture units and ROPs suggests it was tuned for traditional rasterization-heavy rendering, but its pixel rate undercuts that theory. The data indicates the GTX 580M's architectural strengths do not translate into benchmark wins in the recorded tests. In the only head-to-head benchmark, the GTX 750 wins outright, and the GTX 580M has no recorded wins in any other comparison.

The Verdict

The database is unambiguous: the NVIDIA GeForce GTX 750 outperforms the NVIDIA GeForce GTX 580M in the only shared benchmark, with a 45.8% lead in Geekbench OpenCL. The GTX 750 also has a higher average benchmark score (7222 versus 6389), a higher percentile ranking (40th versus 37th), and superior FP32 throughput (1,111.0 GFLOPS versus 952.3 GFLOPS). For anyone choosing between these two for compute workloads, the GTX 750 is the clear pick.

The GTX 580M does have advantages in memory capacity (2 GB versus 1 GB), bandwidth (96.00 GB/s versus 80.19 GB/s), and texture rate (39.68 GTexel/s versus 34.72 GTexel/s), but none of these translate into a benchmark win in the recorded data. Its 100 W TDP is nearly double the GTX 750's 55 W, and its 40 nm process node is a generation behind the 28 nm node used by the GTX 750. The GTX 580M's 332 mm² die is more than double the GTX 750's 148 mm², yet it delivers less compute performance.

The GTX 750 is also the more recent release, launched in February 2014 versus June 2011 for the GTX 580M. Both are end-of-life products, but the GTX 750 belongs to the GeForce 700 generation, while the GTX 580M belongs to the GeForce 500M generation. The GTX 750's successors are the GeForce 900 series, and the GTX 580M's successors are the GeForce 600M series. The GTX 750 has a recorded launch MSRP of 119 USD, while the GTX 580M has no recorded launch price.

The GTX 580M is a mobile MXM module, so direct desktop comparisons are somewhat artificial, but the benchmark data still applies. If the use case is a laptop with an MXM-B slot and the need for 2 GB of VRAM, the GTX 580M is the only option of the two. For desktop users, the GTX 750 is the superior choice in every measured dimension except memory size and texture throughput, and its lower power draw makes it easier to integrate into compact systems.
