AMD Radeon HD 8750M vs AMD Radeon R7 M465 Comparison

Head-to-Head Benchmarks

The sole benchmark in the comparison, Geekbench OpenCL, shows the AMD Radeon HD 8750M ahead of the AMD Radeon R7 M465 by a margin of 2.2%. The HD 8750M scores 5970, while the R7 M465 scores 5841. This is a narrow victory, but it places the older card in a slightly better position for general compute workloads as measured by this specific test.

Context from the nearestRivals data reinforces this modest lead. The HD 8750M’s average score of 5970 places it essentially on par with the NVIDIA Quadro K4000 (5982, delta -0.2%) and slightly ahead of the Quadro K620M (5957, delta 0.2%). The R7 M465, by contrast, is a touch behind the AMD Radeon R5 M435 (5859, delta -0.3%) and trails the Intel UHD Graphics 730 (5929, delta -1.5%). While the two cards are only separated by 129 points in absolute terms, their positions relative to their nearest rivals are distinct.

It is importantly the HD 8750M also edges out its own sibling, the AMD Radeon HD 8730M, with a delta of 0.3%, while the R7 M465 falls behind the same HD 8730M by 1.9%. This suggests that the R7 M465, despite being a newer generation part, does not offer a raw compute advantage in this benchmark. The data shows a clear, albeit small, win for the older HD 8750M in the only head-to-head metric available.

The Verdict

Based strictly on the benchmark data, the AMD Radeon HD 8750M is the better performer in the single available test. Its 2.2% lead in Geekbench OpenCL, combined with a higher percentile ranking (34th vs 33rd), makes it the clear pick for users prioritizing raw compute scores over all other factors. The HD 8750M also holds a more favorable position against shared rivals, outperforming the HD 8730M rather than trailing it like the R7 M465 does.

However, the R7 M465 is not without its own advantages, which become apparent when examining the specification differences. The choice between the two should therefore hinge on whether the user values the modest compute lead of the HD 8750M or the newer feature set and memory configuration of the R7 M465. For a pure benchmark score, the HD 8750M is the winner. For users who require newer API support or double the VRAM, the R7 M465 may be the more practical choice despite its lower score.

Specification Differences

The two GPUs diverge significantly in their memory subsystems and clock speeds. The HD 8750M uses 1024 MB of DDR3 memory on a 128-bit bus, yielding a bandwidth of 28.80 GB/s. The R7 M465, in contrast, offers 2 GB of GDDR5 memory on a narrower 64-bit bus, resulting in a higher bandwidth of 36.00 GB/s. This represents a 25% bandwidth advantage for the R7 M465, despite the narrower bus.

Clock speeds also differ. The HD 8750M has a base clock of 775 MHz and a boost clock of 825 MHz. The R7 M465 has a lower base clock of 730 MHz but a significantly higher boost clock of 1024 MHz. Memory clock speeds are also distinct: the HD 8750M runs at 900 MHz (1800 Mbps effective), while the R7 M465 runs at 1125 MHz (4.5 Gbps effective).

The compute rates reflect these differences. The HD 8750M achieves a pixel rate of 6.600 GPixel/s and a texture rate of 19.80 GTexel/s, while the R7 M465 achieves 8.192 GPixel/s and 24.58 GTexel/s respectively. Floating-point performance also favors the R7 M465, with an FP32 rating of 786.4 GFLOPS versus 633.6 GFLOPS for the HD 8750M. The R7 M465 also lists FP16 performance at 786.4 GFLOPS (1:1), a feature the HD 8750M does not specify.

Architecture Differences

The architectural gap between these two GPUs is substantial. The HD 8750M is built on GCN 1.0 architecture, using the Mars chip, and belongs to the Solar System generation (HD 8700M). The R7 M465 uses the newer GCN 3.0 architecture, with a Topaz chip, and is part of the Gem System generation (R7 M400). This generational leap is evident in several key areas.

Both are fabricated on a 28 nm process at TSMC, but the die details differ. The HD 8750M has 950 million transistors on a 77 mm² die, while the R7 M465 packs 1,550 million transistors on a 125 mm² die. Transistor density is nearly identical, at 12.3M / mm² for the HD 8750M and 12.4M / mm² for the R7 M465.

Core counts are identical: both have 384 shading units, 24 texture mapping units, and 8 ROPs. The key architectural difference lies in API support. The HD 8750M supports DirectX 12 (11_1), while the R7 M465 supports DirectX 12 (12_0). Both support OpenGL 4.6 and Vulkan 1.2.170. The R7 M465’s GCN 3.0 architecture also enables its FP16 compute capability, which is absent from the older GCN 1.0 part.

Release dates and product lineage also differ. The HD 8750M was released on 2013-02-25, succeeding "London" and preceding "Gem System". The R7 M465 was released on 2016-05-14, succeeding "Solar System" and preceding "Polaris Mobile". Both are end-of-life products, and both use a PCIe 3.0 x8 bus interface.

Where Each One Wins

The AMD Radeon HD 8750M wins outright in the benchmark department, taking the sole Geekbench OpenCL test with a score of 5970. This makes it the stronger choice for users who rely on general-purpose compute performance as measured by this benchmark. It also holds a better standing against shared rivals, outperforming the HD 8730M where the R7 M465 falls behind.

The AMD Radeon R7 M465, despite losing the benchmark, wins in several specification-driven categories. Its memory bandwidth of 36.00 GB/s is 25% higher, which could translate to better performance in memory-bound tasks, even if the raw compute score is lower. Its 2 GB VRAM capacity is double that of the HD 8750M, making it more suitable for workloads or applications that require larger frame buffers. The higher boost clock of 1024 MHz and improved pixel and texture rates (8.192 GPixel/s and 24.58 GTexel/s) also suggest it may handle certain graphics workloads more efficiently.

Additionally, the R7 M465’s GCN 3.0 architecture with DirectX 12 (12_0) support provides a more modern feature set compared to the HD 8750M’s DirectX 12 (11_1). The FP16 compute capability of the R7 M465, listed at 786.4 GFLOPS, could also be an advantage in applications that leverage half-precision arithmetic. In summary, the HD 8750M wins on the measured benchmark, while the R7 M465 wins on memory capacity, bandwidth, and architectural modernity.
