AMD Radeon HD 8750M vs AMD Radeon R7 M350 Comparison

# AMD Radeon R7 M350 vs AMD Radeon HD 8750M

The AMD Radeon R7 M350 and AMD Radeon HD 8750M are two end-of-life mobile GPUs from different AMD generations, but the benchmark data shows a clear overall winner. In the single head-to-head benchmark available, the R7 M350 outscores the HD 8750M by 17.1%, with the R7 M350 achieving a Geekbench OpenCL score of 6991 against the HD 8750M's 5970. This places the R7 M350 in the 36th percentile of all GPUs, while the HD 8750M sits at the 34th percentile. The R7 M350 also has a higher average benchmark score of 6327 versus 5970 for the HD 8750M, which is consistent with its newer architecture and higher clock speeds.

Head-to-Head Benchmarks

The only direct benchmark comparison available is Geekbench OpenCL, and the results are unambiguous. The Radeon R7 M350 scores 6991, which is 17.1% higher than the HD 8750M's 5970. That is a substantial margin for two GPUs that share the same core counts—both have 384 shading units, 24 texture mapping units, and 8 raster operation units. The difference comes down to execution efficiency and clock speeds rather than raw hardware resources.

Looking at the nearest rivals for each card puts this performance gap into perspective. The R7 M350's average score of 6327 is essentially tied with the AMD Radeon Pro WX 4100 (6330, 0% delta), and it sits just ahead of the NVIDIA Quadro K620 (6282, 0.7% delta). The HD 8750M's average score of 5970 is within 0.2% of the NVIDIA Quadro K4000 (5982) and within 0.3% of the AMD Radeon HD 8730M (5955). In other words, the R7 M350 competes in a slightly higher performance tier than the HD 8750M, even though neither card is anywhere near modern desktop GPU performance levels.

The R7 M350 wins the only head-to-head benchmark, and there are no benchmark categories where the HD 8750M comes out ahead. The wins tally is 1 for the R7 M350 and 0 for the HD 8750M. That is a clean sweep, though it is based on a single test. The Geekbench OpenCL workload is compute-heavy, which tends to favor architectures with better instruction efficiency and higher clock rates—both areas where the R7 M350 holds an advantage.

Where Each One Wins

The Radeon R7 M350 wins in every measurable category from the data. Its Geekbench OpenCL score of 6991 is 17.1% higher than the HD 8750M's 5970. The R7 M350 also has a higher average benchmark score (6327 vs 5970), a higher percentile ranking (36th vs 34th), and superior raw throughput metrics across the board. Its pixel rate is 8.120 GPixel/s versus 6.600 GPixel/s for the HD 8750M, and its texture rate is 24.36 GTexel/s versus 19.80 GTexel/s. Floating-point performance follows the same pattern: 779.5 GFLOPS for the R7 M350 versus 633.6 GFLOPS for the HD 8750M.

If you are choosing between these two for a legacy system, the R7 M350 is the better pick for any OpenCL-accelerated workload, including video encoding, image processing, or compute tasks. The HD 8750M does have one practical advantage: its 128-bit memory bus provides 28.80 GB/s of bandwidth compared to the R7 M350's 64-bit bus at 16.00 GB/s. However, this bandwidth advantage does not translate into a benchmark win—the R7 M350's higher clocks and newer architecture more than compensate. For gaming, neither card is competitive by modern standards, but the R7 M350's higher pixel and texture rates suggest it would handle older titles better. The HD 8750M's larger memory bus could help in bandwidth-sensitive scenarios, but the data shows no test where that translates into a win.

Architecture Differences

The two GPUs come from different GCN iterations. The Radeon R7 M350 uses the Meso chip with GCN 3.0 architecture, while the HD 8750M uses the Mars chip with GCN 1.0. Both are built on TSMC's 28 nm process, but the R7 M350 packs more transistors: 1,550 million versus 950 million for the HD 8750M. The die sizes also differ significantly—125 mm² for the R7 M350 versus 77 mm² for the HD 8750M. Transistor density is nearly identical (12.4M per mm² for the R7 M350, 12.3M per mm² for the HD 8750M), meaning the R7 M350's larger die is simply more silicon rather than denser packing.

Clock speeds favor the R7 M350 substantially. Its base clock is 1000 MHz with a boost of 1015 MHz, compared to the HD 8750M's 775 MHz base and 825 MHz boost. That is a 29% higher base clock and a 23% higher boost clock. Memory clocks also differ: the R7 M350 runs its DDR3 at 1000 MHz (2 Gbps effective), while the HD 8750M runs at 900 MHz (1800 Mbps effective). The R7 M350 supports DirectX 12 (12_0), whereas the HD 8750M is limited to DirectX 12 (11_1). Both support OpenGL 4.6 and Vulkan 1.2.170. The R7 M350 also has FP16 performance rated at 779.5 GFLOPS (1:1 with FP32), while the HD 8750M has no FP16 rating listed.

Memory configurations differ in capacity and bus width. The R7 M350 comes with 4 GB of DDR3 on a 64-bit bus, providing 16.00 GB/s of bandwidth. The HD 8750M has 1024 MB (1 GB) of DDR3 on a 128-bit bus, providing 28.80 GB/s. The HD 8750M has more than 80% higher memory bandwidth, but that advantage is nullified in practice by its lower clocks and older architecture. Both use PCIe 3.0 x8 interfaces. The R7 M350's generation is listed as "Gem System (R7 M300)," and the HD 8750M's is "Solar System (HD 8700M)." The R7 M350's predecessor is Solar System, and its successor is Polaris Mobile; the HD 8750M's predecessor is London, and its successor is Gem System.

The Verdict

The data points decisively to the AMD Radeon R7 M350 as the superior GPU. It wins the only head-to-head benchmark by 17.1%, has a higher average benchmark score (6327 vs 5970), and ranks in a higher percentile (36th vs 34th). Its clock advantage is massive—1000 MHz base versus 775 MHz base—and it offers double the memory capacity at 4 GB versus 1 GB. The R7 M350 also brings newer GCN 3.0 architecture, better DirectX 12 support, and FP16 compute capability.

The HD 8750M's only statistical advantages are memory bandwidth (28.80 GB/s vs 16.00 GB/s) and a wider memory bus (128-bit vs 64-bit). Those specifications do not produce any benchmark win, so they are of limited practical value. If you are building or upgrading a legacy system and must choose between these two, the R7 M350 is the clear pick for compute performance, pixel throughput, and texture throughput. The HD 8750M is not without merit—it is a smaller, simpler chip that might run cooler in some chassis—but the benchmark data shows no scenario where it outperforms its newer sibling. Choose the R7 M350 for better OpenCL scores, higher clocks, and more memory; choose the HD 8750M only if you specifically need the higher memory bandwidth for a niche workload and are willing to sacrifice 17.1% compute performance.
