AMD Radeon R5 M240 vs NVIDIA GeForce GTX 750 Comparison

Where Each One Wins

The benchmark data presents a lopsided contest. The NVIDIA GeForce GTX 750 wins the only head-to-head benchmark available, the Geekbench OpenCL test, by a decisive 33.5% margin. The AMD Radeon R5 M240 does not win a single benchmark in the comparison, making the use-case split clear: the GTX 750 is the performance leader across the board, while the R5 M240 has no demonstrated strength where it outpaces its rival.

Looking at the broader benchmark context, the GTX 750’s average benchmark score of 7,222 places it in the 40th percentile of all GPUs, while the R5 M240’s average score of 6,975 sits at the 39th percentile. The 247-point gap between their averages is modest in percentile terms, yet the OpenCL head-to-head shows a much larger 33.5% disparity. This suggests that the GTX 750’s advantage is consistent and pronounced in compute workloads, even if both cards occupy similar positions in the overall GPU hierarchy.

For specific workloads, the GTX 750 also has additional benchmark data points that the R5 M240 lacks. The GTX 750 scores 4,274 in Geekbench Metal and 8,078 in Geekbench Vulkan, demonstrating versatility across multiple API environments. The R5 M240 only has a single OpenCL result, so its performance in Metal or Vulkan workloads cannot be assessed from this data. This means that for users targeting those specific APIs, the GTX 750 is the only one of the two with verified performance numbers.

Architecture Differences

The architectural divide between these two GPUs is substantial, beginning with the chip designs themselves. The GTX 750 uses the GM107 chip built on NVIDIA’s Maxwell architecture, while the R5 M240 relies on the Jet chip based on AMD’s GCN 1.0 architecture. Both are fabricated on the same 28 nm process at TSMC, but the similarities end there.

The transistor counts and die sizes tell a story of different design philosophies. The GTX 750 packs 1,870 million transistors into a 148 mm² die, yielding a transistor density of 12.6 million per mm². The R5 M240 uses only 690 million transistors on a 56 mm² die, with a nearly identical density of 12.3 million per mm². The GTX 750’s die is roughly 2.6 times larger, which correlates with its substantially higher compute resources.

The compute configurations diverge sharply. The GTX 750 features 512 shading units, 32 texture mapping units, and 16 raster output units. The R5 M240 has 320 shading units, 20 TMUs, and 8 ROPs. This means the GTX 750 has 60% more shading units, 60% more TMUs, and double the ROPs. These differences translate directly into throughput: the GTX 750 achieves 1,111 GFLOPS of FP32 performance versus 659.2 GFLOPS for the R5 M240, a 68.5% advantage. Pixel rates are 17.36 GPixel/s versus 8.24 GPixel/s, and texture rates are 34.72 GTexel/s versus 20.60 GTexel/s.

Memory subsystems also differ fundamentally. The GTX 750 uses 1,024 MB of GDDR5 on a 128-bit bus, delivering 80.19 GB/s of bandwidth. The R5 M240 also has 1,024 MB but uses DDR3 on a 64-bit bus, yielding just 14.40 GB/s. That is a 5.6x bandwidth gap, which has major implications for memory-bound workloads. Clock speeds are similar—the GTX 750 runs at 1020 MHz base and 1085 MHz boost, while the R5 M240 runs at 1000 MHz base and 1030 MHz boost—so the performance difference comes almost entirely from the wider memory bus, faster memory type, and higher compute resource counts.

API support shows minor differences. The GTX 750 supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.4. The R5 M240 supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The GTX 750 has a newer Vulkan version, while the R5 M240 has a slightly higher DirectX feature level. Neither card supports hardware ray tracing or tensor cores, as both lack those units.

The Verdict

The data points to a clear winner. The NVIDIA GeForce GTX 750 outperforms the AMD Radeon R5 M240 in every measurable category. The 33.5% OpenCL lead is the headline result, but the underlying specifications reinforce it: more shading units, more TMUs, more ROPs, higher memory bandwidth, and greater FP32 throughput. The GTX 750 also has a 40th percentile rank versus the R5 M240’s 39th, and its nearest rivals include the AMD Radeon Vega 8 Mobile (0.3% ahead) and the NVIDIA GeForce GTX 970 (0.9% behind), showing it competes in a tighter cluster than the R5 M240, whose rivals include the NVIDIA GeForce GTX 680M (0.7% ahead) and the NVIDIA T600 (0.8% ahead).

Who should pick the GTX 750? Anyone needing verified performance across multiple APIs—OpenCL, Metal, and Vulkan—since only the GTX 750 has benchmark scores for all three. Users running compute workloads will benefit from the 68.5% FP32 advantage and the 5.6x memory bandwidth. The GTX 750 also supports Vulkan 1.4 versus 1.2.170, which may matter for forward-looking applications.

Who should pick the R5 M240? The data offers no performance-based reason. It loses the only head-to-head benchmark, has fewer compute resources, slower memory, and a lower average score. The only potential advantage is its smaller die (56 mm² vs 148 mm²), which might imply lower power draw, but the fact pack provides no TDP for the R5 M240, so this cannot be confirmed. The R5 M240’s DirectX 12 (11_1) support is marginally higher than the GTX 750’s 11_0, but that is a narrow edge with no benchmark evidence to back it up.

The verdict is straightforward: the GTX 750 wins on every data point available. The R5 M240 is only defensible if the DirectX feature-level difference or smaller silicon footprint is critical, but neither is substantiated by benchmark results.

Head-to-Head Benchmarks

The single head-to-head benchmark is Geekbench OpenCL, and it is not close. The GTX 750 scores 9,315 against the R5 M240’s 6,975, producing a 33.5% delta in favor of NVIDIA. To put that in perspective, the GTX 750’s nearest rivals include the AMD Radeon Vega 8 Mobile at 7,203 (0.3% higher) and the NVIDIA GeForce GTX 560 SE at 7,171 (0.7% higher). The R5 M240’s nearest rivals include the NVIDIA GeForce GTX 680M at 7,023 (0.7% higher) and the NVIDIA T600 at 7,035 (0.8% higher). Notably, the R5 M240’s OpenCL score of 6,975 is lower than every one of the GTX 750’s nearest rivals, meaning the R5 M240 would sit below the GTX 750’s entire competitive cluster.

The 33.5% margin in OpenCL is consistent with the raw specification gaps. The GTX 750’s FP32 throughput of 1,111 GFLOPS is 68.5% higher than the R5 M240’s 659.2 GFLOPS, and its memory bandwidth of 80.19 GB/s is 5.6x higher. Even though the R5 M240’s boost clock of 1030 MHz is only 55 MHz lower than the GTX 750’s 1085 MHz boost, the compute resource disparity overwhelms the clock speed similarity. The GTX 750’s pixel rate of 17.36 GPixel/s is more than double the R5 M240’s 8.24 GPixel/s, and its texture rate of 34.72 GTexel/s is 68.5% higher than 20.60 GTexel/s.

There is no benchmark where the R5 M240 wins. The data shows zero wins for AMD. The GTX 750 also has additional benchmark results—4,274 in Metal and 8,078 in Vulkan—that the R5 M240 cannot match because it has no such results. In Vulkan, the GTX 750’s score of 8,078 is higher than its own OpenCL score of 9,315 only by 13.3%, but the R5 M240 has no Vulkan data for comparison.
