AMD Radeon R9 M375X vs NVIDIA GeForce GTX 750 Comparison

Head-to-Head Benchmarks

The dataset includes two direct benchmark comparisons between the AMD Radeon R9 M375X and the NVIDIA GeForce GTX 750. These results split cleanly, with each card taking one workload category.

In Geekbench OpenCL, the NVIDIA GeForce GTX 750 posts a score of 9315, which is 11.2% ahead of the AMD Radeon R9 M375X at 8273. That is a substantial margin for a single benchmark, and it reflects the GTX 750's advantage in raw compute throughput as measured by OpenCL. The R9 M375X trails by more than a thousand points, a gap large enough to matter in any application that scales well with OpenCL performance.

The Vulkan result flips the outcome. The AMD Radeon R9 M375X scores 8377, which is 3.7% higher than the GTX 750's 8078. The delta is smaller than the OpenCL margin, but it still gives AMD the win in this API. Vulkan workloads tend to favor architectural efficiency and driver overhead characteristics, and the data shows the R9 M375X holding a measurable edge here.

When looking at average benchmark scores, the picture becomes more complicated. The AMD card averages 8325 across its recorded tests, while the NVIDIA card averages 7222. That difference is heavily influenced by the fact that the GTX 750 also includes a Geekbench Metal result of 4274, which drags its average down. The R9 M375X has no recorded Metal score, so its average reflects only its OpenCL and Vulkan results. For direct comparisons, the head-to-head numbers are the more reliable indicator.

The percentile rankings place both cards in similar territory. The AMD Radeon R9 M375X sits at the 43rd percentile among all GPUs, while the GTX 750 sits at the 40th percentile. Both are entry-level to mid-range parts by modern standards, and the benchmark data confirms they occupy adjacent performance tiers.

Where Each One Wins

The NVIDIA GeForce GTX 750 wins decisively in OpenCL compute. With an 11.2% lead over the AMD Radeon R9 M375X, it is the better choice for applications that rely on OpenCL acceleration, such as certain video encoding tasks, physics simulations, and productivity workloads that offload to the GPU. The GTX 750's 9315 OpenCL score also sits above the average scores of its nearest rivals, including the NVIDIA Quadro K1200 at 8265 and the AMD Radeon 880M at 8436, placing it in a strong position within its performance class.

The AMD Radeon R9 M375X wins in Vulkan. Its 8377 score beats the GTX 750's 8078 by 3.7%, which makes it the preferable option for Vulkan-based games and compute applications. Vulkan adoption in modern titles makes this relevant, even if the absolute performance level is modest. The R9 M375X also has a higher average benchmark score of 8325 compared to the GTX 750's 7222, though that metric includes the GTX 750's Metal result, which is not directly comparable.

For gaming, the choice depends on API support. Older titles using OpenGL or DirectX 11 will favor the GTX 750's OpenCL strength indirectly, since that same compute architecture drives its rendering performance. Newer titles with Vulkan paths will behave differently, and the R9 M375X's Vulkan advantage suggests it holds up better in those scenarios. The GTX 750 supports DirectX 12 (11_0), while the R9 M375X supports DirectX 12 (11_1), a small but real difference in feature level.

Architecture Differences

The AMD Radeon R9 M375X uses the Tropo chip built on GCN 1.0 architecture, manufactured by TSMC on a 28 nm process. The die measures 123 mm² and contains 1,500 million transistors, yielding a transistor density of 12.2 million per square millimeter. This is AMD's first-generation Graphics Core Next design, which introduced unified shaders and a compute-first approach.

The NVIDIA GeForce GTX 750 uses the GM107 chip built on Maxwell architecture, also manufactured by TSMC on 28 nm. The die is larger at 148 mm² and packs 1,870 million transistors, resulting in a slightly higher density of 12.6 million per square millimeter. Maxwell was designed with efficiency as a priority, and the GTX 750 reflects that with a 55 W TDP and no external power connectors.

The compute configurations differ significantly. The R9 M375X has 640 shading units, 40 texture mapping units, and 16 raster output units. The GTX 750 has 512 shading units, 32 TMUs, and 16 ROPs. Despite having fewer shaders and TMUs, the GTX 750 achieves higher pixel and texture rates. Its pixel rate is 17.36 GPixel/s versus 16.24 GPixel/s for the AMD card, and its texture rate is 34.72 GTexel/s versus 40.60 GTexel/s for the AMD card. The AMD card wins on texture rate thanks to its 40 TMUs, but NVIDIA's higher clock speeds help close the pixel rate gap.

Clock speeds favor NVIDIA. The GTX 750 runs at 1020 MHz base and 1085 MHz boost, while the R9 M375X runs at 925 MHz base and 1015 MHz boost. Memory clocks also favor NVIDIA: 1253 MHz (5 Gbps effective) versus 1125 MHz (4.5 Gbps effective). This translates to 80.19 GB/s of memory bandwidth for the GTX 750 versus 72.00 GB/s for the R9 M375X, both over 128-bit buses.

FP32 compute shows the AMD card ahead on paper. The R9 M375X delivers 1,299.2 GFLOPS versus 1,111.0 GFLOPS for the GTX 750. The AMD card's extra shading units compensate for its lower clocks. Neither card has RT cores or tensor cores, and neither supports FP16 operations in the recorded specifications.

API support differs slightly. The R9 M375X lists DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The GTX 750 lists DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.4. NVIDIA's newer Vulkan version is notable, though the head-to-head Vulkan benchmark still favors AMD.

The Verdict

The NVIDIA GeForce GTX 750 is the stronger choice for OpenCL-centric workloads and for users who prioritize power efficiency. Its 55 W TDP, lack of power connectors, and single-slot design make it an easy drop into existing systems. Its 11.2% OpenCL lead over the R9 M375X is the largest performance gap in the head-to-head data, and its 80.19 GB/s memory bandwidth gives it a throughput advantage that matters in memory-bound tasks.

The AMD Radeon R9 M375X is the better pick for Vulkan-based applications. Its 3.7% Vulkan win demonstrates that its GCN architecture handles modern APIs competently, and its higher shading unit count provides theoretical compute headroom. The R9 M375X also delivers higher FP32 throughput at 1,299.2 GFLOPS versus 1,111.0 GFLOPS, which can benefit workloads that scale with raw shader count rather than memory bandwidth.

For gaming, the decision hinges on the game's API and the user's tolerance for older hardware. The GTX 750's higher clocks and faster memory make it the conventional choice for DirectX 11-era titles, while the R9 M375X's Vulkan advantage suggests it ages better in newer games that use Vulkan. Neither card is competitive by modern standards, as both sit below the 50th percentile in the global GPU ranking.

Users who want a simple, low-power card with proven OpenCL muscle should take the GTX 750. Users who need Vulkan performance or who favor AMD's compute architecture should take the R9 M375X. The recorded benchmark data does not support a universal winner, only a workload-dependent one.
