AMD Radeon R7 M465 vs NVIDIA GeForce GTX 670MX Comparison

Head-to-Head Benchmarks

The only direct benchmark comparison available is Geekbench OpenCL, and the NVIDIA GeForce GTX 670MX takes the win with a score of 6,125 against the AMD Radeon R7 M465's 5,841. That is a 4.6% advantage for NVIDIA. In practical terms, this is a modest but measurable lead — the kind of margin that shows up in compute workloads but not necessarily in every frame rate.

Looking at the broader context, both cards sit at the 33rd percentile among all GPUs, meaning they are statistically peers in the overall performance distribution. The GTX 670MX's average benchmark score of 5,721 is actually lower than its OpenCL result, while the R7 M465's average matches its OpenCL score exactly at 5,841. That distinction matters: the R7 M465 is consistent, while the GTX 670MX has a higher peak but a lower average across whatever benchmarks contribute to that figure.

When comparing the R7 M465 to its nearest rivals, the data shows it is essentially a middle-of-the-pack mobile part. It trails the AMD Radeon R5 M435 by 0.3% (5,859 vs. 5,841), sits 1.5% behind the Intel UHD Graphics 730 (5,929), and beats the NVIDIA GeForce GTX 550 Ti by 1.9% (5,731). The R7 M465 also lags the AMD Radeon HD 8730M by 1.9% (5,955). These are all within a 3% band, so the R7 M465 is not a standout — it is simply competitive with its direct contemporaries.

The GTX 670MX's nearest rivals tell a similar story. It edges out the Intel Iris Pro Graphics P6300 by 0.2% (5,712), loses by the same 0.2% to the GTX 550 Ti (5,731), beats the AMD Radeon HD 8790M by 0.5% (5,691), and leads the NVIDIA Quadro M500M by 2.1% (5,604). Notably, the GTX 670MX also has a Geekbench Vulkan score of 5,316, which is significantly lower than its OpenCL result — a 13.2% gap. That suggests the Kepler architecture is stronger under OpenCL than Vulkan, which is worth keeping in mind if you plan to run Vulkan-based titles or compute.

The head-to-head delta of -4.6% is the single largest comparable margin in this matchup, but it is hardly a landslide. For a builder choosing between two used or budget laptops, this difference is real but not transformative.

Architecture Differences

The architectural gap here is substantial. The AMD Radeon R7 M465 uses the Topaz chip built on GCN 3.0, fabricated by TSMC on a 28 nm process. It packs 1,550 million transistors into a 125 mm² die, giving a transistor density of 12.4 million per square millimeter. The NVIDIA GeForce GTX 670MX, by contrast, uses the GK104 chip on the Kepler architecture, also from TSMC at 28 nm, but with 3,540 million transistors on a much larger 294 mm² die — a density of 12.0 million per square millimeter. The NVIDIA part is more than twice the die size and has more than double the transistor count.

Clock speeds tell a different story. The R7 M465 runs at a 730 MHz base clock with a 1024 MHz boost — a 40% boost headroom. The GTX 670MX is locked at a flat 601 MHz for both base and boost, which is a much more conservative approach. Despite lower clocks, the GTX 670MX wins on raw throughput because it has vastly more execution units: 960 shading units, 80 texture mapping units, and 24 ROPs, versus the R7 M465's 384 shading units, 24 TMUs, and 8 ROPs.

These unit counts translate directly into computed rates. The GTX 670MX achieves 12.02 GPixel/s pixel fill rate and 48.08 GTexel/s texture rate, while the R7 M465 manages 8.192 GPixel/s and 24.58 GTexel/s. In FP32 compute, the NVIDIA part delivers 1,153.9 GFLOPS against the AMD part's 786.4 GFLOPS — a 46.7% advantage. The R7 M465 does match its FP32 rate in FP16 (786.4 GFLOPS, 1:1), while the GTX 670MX has no listed FP16 capability.

Memory is another clear separation. The R7 M465 has 2 GB of GDDR5 on a 64-bit bus, yielding 36.00 GB/s bandwidth. The GTX 670MX has 3 GB of GDDR5 on a 192-bit bus, delivering 67.20 GB/s — nearly double the bandwidth. The NVIDIA card also runs its memory at 700 MHz (2.8 Gbps effective), while the AMD card runs at 1125 MHz (4.5 Gbps effective), yet the wider bus more than compensates.

The GTX 670MX has a listed TDP of 75 W, while the R7 M465 has no TDP figure in the data. The NVIDIA card also lists no power connectors, suggesting it draws entirely from the PCIe slot or motherboard. Bus interface differs too: the R7 M465 uses PCIe 3.0 x8, while the GTX 670MX uses PCIe 3.0 x16. Both support DirectX 12, but the R7 M465 is at feature level 12_0 while the GTX 670MX is at 11_0. Both support OpenGL 4.6. Vulkan support is present on both, with versions 1.2.170 (AMD) and 1.2.175 (NVIDIA).

Where Each One Wins

The GTX 670MX wins the only direct benchmark, and it wins on nearly every raw specification. If you need compute throughput, the 46.7% FP32 advantage is decisive. If you need memory bandwidth, the 67.20 GB/s vs. 36.00 GB/s is a 86.7% lead. The GTX 670MX also has more VRAM (3 GB vs. 2 GB), which helps with larger textures or higher resolutions. For texture-heavy workloads, the 48.08 GTexel/s rate is roughly double the R7 M465's 24.58 GTexel/s.

The R7 M465's wins are more subtle. It has a much higher boost clock (1024 MHz vs. 601 MHz), which could help in lightly-threaded scenarios where clock speed matters more than parallel throughput. It also has a higher memory clock (1125 MHz vs. 700 MHz), though the effective bandwidth is still far lower. The R7 M465's DirectX 12 feature level 12_0 is newer than the GTX 670MX's 11_0, which may matter for certain modern titles or features. Additionally, the R7 M465 is part of the Gem System (R7 M400) generation from 2016, while the GTX 670MX is from the GeForce 600M generation (2012) — four years older.

In terms of benchmark consistency, the R7 M465 has a single benchmark score that equals its average, while the GTX 670MX's average is dragged down by its Vulkan result. If you care about predictable performance, the R7 M465 is steadier. If you care about peak performance, the GTX 670MX has the edge.

The Verdict

From the data alone, the NVIDIA GeForce GTX 670MX is the stronger GPU in head-to-head OpenCL compute, beating the AMD Radeon R7 M465 by 4.6%. It also leads in every architectural specification that matters for raw performance: shading units (960 vs. 384), TMUs (80 vs. 24), ROPs (24 vs. 8), FP32 (1,153.9 vs. 786.4 GFLOPS), texture rate (48.08 vs. 24.58 GTexel/s), pixel rate (12.02 vs. 8.192 GPixel/s), and memory bandwidth (67.20 vs. 36.00 GB/s). It has more VRAM and a wider bus. If you are choosing purely on performance, the GTX 670MX is the pick.

However, the R7 M465 is not without merit. It is a newer design from 2016, has a higher boost clock, newer DirectX 12 feature level, and its benchmark score is more consistent. It also has a higher transistor density on a smaller die, which suggests better manufacturing efficiency. If you are building a system where power draw is a concern (the GTX 670MX is rated at 75 W, the R7 M465 has no TDP listed), the AMD part may be the safer bet.

The verdict depends on your priorities. For gaming or compute tasks where maximum FPS or throughput is the goal, the GTX 670MX is the clear choice — it wins the benchmark and dominates the spec sheet. For a lighter, newer, more efficient laptop GPU that still holds its own in OpenCL, the R7 M465 is acceptable, but it is simply outclassed on raw capability. The data does not support picking the AMD part for performance reasons; it only makes sense if the newer feature set or lower power draw is a deciding factor.
