Architecture Differences

Both the AMD Radeon R7 M460 and the AMD Radeon R7 M465 belong to the same Gem System (R7 M400) generation and share the GCN 3.0 architecture. The fundamental silicon is nearly identical: both use a 28 nm process at TSMC, pack 1,550 million transistors on a 125 mm² die, and reach a transistor density of 12.4M per mm². The chip names differ, however. The R7 M460 is built around the Meso chip, while the R7 M465 uses the Topaz chip. This is the primary architectural distinction between the two parts.

The compute resources are unchanged across the boards. Each GPU has 384 shading units, 24 texture mapping units, and 8 ROPs. The pixel rate is 8.192 GPixel/s for both, and the texture rate is 24.58 GTexel/s. Floating-point performance matches exactly: 786.4 GFLOPS for FP32 and the same 786.4 GFLOPS for FP16, with a 1:1 ratio between the two. The absence of dedicated ray tracing cores and tensor cores is consistent across both products, reflecting their GCN 3.0 design point.

Clock behavior is also identical. The base clock sits at 730 MHz and the boost clock reaches 1024 MHz for both GPUs. The memory subsystem is a direct copy: 2 GB of GDDR5, a 64-bit bus, 36.00 GB/s bandwidth, and a memory clock of 1125 MHz with 4.5 Gbps effective data rate. The bus interface is PCIe 3.0 x8 for both.

The API support is uniform as well. Each GPU exposes DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The production status is end-of-life for both, with the same release date of May 14, 2016. The predecessor is Solar System and the successor is Polaris Mobile for both entries. The only meaningful architectural difference in the database is the chip designation: Meso versus Topaz. That chip swap does not translate into any measurable difference in core counts, clock speeds, or memory throughput.

The Verdict

The benchmark data is unambiguous: the AMD Radeon R7 M460 is the faster part. In the single recorded OpenCL test, the M460 scores 6612 against 5841 for the M465, a 13.2% gap. The M460 wins the head-to-head sweep with 1 win and 0 losses. The database also confirms this with percentiles: the M460 lands at the 38th percentile of all GPUs, while the M465 sits at the 33rd.

Who should choose the R7 M460? Anyone looking for the stronger compute performance within this pair. The 13.2% lead in OpenCL is meaningful for GPU-accelerated workloads that scale with raw shading throughput. The M460 also holds its own against its nearest rivals, with a 0.5% edge over the HD 7730M and a 0.9% lead over the Intel UHD Graphics P750. It trails the NVIDIA GeForce GT 1010 by 1.3%, which is a close margin. The M460 is the default pick when both cards are available.

Who should choose the R7 M465? The data does not give a clear reason to prefer it. It scores lower in OpenCL, ranks in a lower percentile, and its nearest rival, the R5 M435, beats it by 0.3%. The M465 sits 1.5% behind the Intel UHD Graphics 730 and 1.9% behind the AMD Radeon HD 8730M. It does edge out the NVIDIA GeForce GTX 550 Ti by 1.9%, but that is the only positive comparison in its rival set. If the choice is strictly between these two AMD parts, the M460 is the recommended option. The M465 is a fallback only when the M460 is not available, since its performance profile is nearly identical in architecture but measurably weaker in execution.

Specification Differences

The two GPUs are specification twins except for the chip name and benchmark results. The database lists the R7 M460's chip as Meso and the R7 M465's chip as Topaz. Every other hardware field is identical.

• Chip: Meso (M460) versus Topaz (M465)
• Geekbench OpenCL score: 6612 (M460) versus 5841 (M465)
• Percentile vs all GPUs: 38 (M460) versus 33 (M465)

The following fields show no difference: architecture (GCN 3.0), process node (28 nm), foundry (TSMC), transistors (1,550 million), die size (125 mm²), transistor density (12.4M / mm²), base clock (730 MHz), boost clock (1024 MHz), memory clock (1125 MHz, 4.5 Gbps effective), memory size (2 GB), memory type (GDDR5), bus width (64 bit), bandwidth (36.00 GB/s), shading units (384), TMUs (24), ROPs (8), pixel rate (8.192 GPixel/s), texture rate (24.58 GTexel/s), FP32 (786.4 GFLOPS), FP16 (786.4 GFLOPS), bus interface (PCIe 3.0 x8), DirectX (12, 12_0), OpenGL (4.6), Vulkan (1.2.170), production status (end-of-life), release date (May 14, 2016), predecessor (Solar System), and successor (Polaris Mobile). TDP, slot width, power connectors, suggested PSU, display outputs, and dimensions are all null in both records.

Head-to-Head Benchmarks

The only head-to-head benchmark in the database is Geekbench OpenCL, and it decisively favors the R7 M460. The M460 posts a score of 6612, while the M465 manages 5841. That is a 13.2% delta in favor of the M460. This is the largest and only recorded win for either card, giving the M460 a 1-0 record in direct comparisons.

The score gap is substantial enough to separate the two parts in real-world compute tasks. OpenCL workloads that scale with shading units and clock speed will show a tangible advantage on the M460. Since both cards have identical shading units, TMUs, ROPs, clocks, and memory bandwidth, the observed difference is likely attributable to the chip design or driver behavior between Meso and Topaz. The database does not provide a reason, but the result is clear.

For context, the M460's nearest rivals bracket its score closely. The AMD Radeon HD 7730M sits at 6581, just 0.5% behind. The Intel UHD Graphics P750 scores 6554, 0.9% behind. The NVIDIA GeForce GT 1010 scores 6698, which is 1.3% ahead of the M460. The NVIDIA GeForce GTX 670M trails at 6513, 1.5% behind the M460. The M460 is therefore competitive with a cluster of GPUs in the 6500 to 6700 range.

The M465 occupies a lower tier. Its nearest rival, the AMD Radeon R5 M435, scores 5859, which is 0.3% above the M465. The Intel UHD Graphics 730 scores 5929, 1.5% higher. The AMD Radeon HD 8730M scores 5955, 1.9% higher. The NVIDIA GeForce GTX 550 Ti scores 5731, which is 1.9% below the M465. This places the M465 in a slower group, roughly 500 to 700 points behind the M460's cohort.

The head-to-head result is the single most important data point in this comparison. The M460 wins the only recorded benchmark, and it does so by a margin that is meaningful in percentile terms: 38th versus 33rd overall. For any application that relies on OpenCL compute, the data says to pick the M460. The M465 is not a competitive alternative within the same product family.
