AMD Radeon R7 M460 vs NVIDIA GeForce GTX 770M Comparison

Head-to-Head Benchmarks

The database records a single direct comparison between these two mobile graphics processors, and the result is decisive. In the Geekbench OpenCL test, the NVIDIA GeForce GTX 770M scores 8552, while the AMD Radeon R7 M460 scores 6612. That puts the NVIDIA part 22.7 percent ahead, a substantial margin for any workload that leverages OpenCL compute.

The gap is significant enough that the GTX 770M's victory is not merely a matter of a few percentage points. It is a clear, repeatable performance tier separation. The AMD Radeon R7 M460 does not close the distance in any measured benchmark, as the head-to-head table shows zero wins for the AMD part and one win for the NVIDIA part.

Context from the broader database reinforces this split. The Radeon R7 M460's average benchmark score is 6612, which places it at the 38th percentile among all GPUs. Its nearest rivals include the AMD Radeon HD 7730M at 6581 (0.5 percent behind), the Intel UHD Graphics P750 at 6554 (0.9 percent behind), and the NVIDIA GeForce GT 1010 at 6698 (1.3 percent ahead). The R7 M460 effectively trades blows with these low-end parts, sometimes edging ahead, sometimes trailing by a hair.

The GeForce GTX 770M presents a different picture. Its average benchmark score is 6000, which is pulled down by the inclusion of a Geekbench Metal result of 3448 in addition to the OpenCL score of 8552. That Metal score is not part of the head-to-head comparison, but it affects the average. The 770M sits at the 35th percentile overall. Its nearest rivals are the AMD Radeon RX 6400 at 6001 (0 percent delta), the NVIDIA RTX PRO 6000 Blackwell Server at 5996 (0.1 percent behind), the AMD FirePro W4100 at 5987 (0.2 percent behind), and the NVIDIA Quadro K4000M at 5986 (0.2 percent behind). So while the 770M's OpenCL result is strong, its aggregate standing is mid-pack due to the Metal variance.

The key takeaway from the head-to-head is that the GTX 770M wins the single OpenCL test by a wide margin. No other benchmark in the database pits these two directly against each other, so the OpenCL result stands as the definitive measured comparison.

Where Each One Wins

Based on the recorded benchmark data, the NVIDIA GeForce GTX 770M wins the only direct comparison. That makes it the clear choice for any workload that relies on OpenCL compute, which includes many general-purpose GPU tasks, certain rendering pipelines, and some scientific applications. The 22.7 percent lead is consistent with the hardware differences detailed in the architecture section below.

The AMD Radeon R7 M460 does not win any benchmark in the head-to-head set. However, it does hold its own against a specific set of rivals in the broader database. Against the AMD Radeon HD 7730M, the R7 M460 is 0.5 percent ahead. Against the Intel UHD Graphics P750, it is 0.9 percent ahead. Against the NVIDIA GeForce GTX 670M, it is 1.5 percent ahead. These are narrow but real advantages over older or integrated solutions.

The use-case split is therefore straightforward. For users who need maximum OpenCL throughput in a mobile workstation or gaming laptop, the GTX 770M is the superior part. For users who are comparing the R7 M460 against older discrete GPUs or integrated graphics, the AMD part offers a modest edge in compute performance. But in a direct contest between the two, the NVIDIA GPU dominates.

Architecture Differences

The two GPUs come from different design philosophies and different eras. The AMD Radeon R7 M460 is built on the Meso chip using the GCN 3.0 architecture, fabricated on a 28 nm process at TSMC. It packs 1,550 million transistors into a die size of 125 mm², giving a transistor density of 12.4 million per square millimeter. The GPU belongs to the Gem System generation within the R7 M400 series, and it was released in May 2016.

The NVIDIA GeForce GTX 770M uses the GK106 chip with the Kepler architecture, also on a 28 nm process at TSMC. It contains 2,540 million transistors spread across a larger 221 mm² die, resulting in a slightly lower transistor density of 11.5 million per square millimeter. The 770M is part of the GeForce 700M generation and was released in May 2013, making it three years older than the AMD part.

The compute resources differ dramatically. The R7 M460 has 384 shading units, 24 texture mapping units, and 8 raster operation units. The GTX 770M has 960 shading units, 80 TMUs, and 24 ROPs. These are not close numbers; the NVIDIA GPU has 2.5 times the shader count and more than three times the TMUs and ROPs. That explains the OpenCL performance gap.

Clock speeds tell a more nuanced story. The R7 M460 runs at a base clock of 730 MHz with a boost of 1024 MHz. The GTX 770M has a lower base clock of 706 MHz and a boost of 797 MHz. Despite the lower clocks, the NVIDIA part wins because it has far more execution units working in parallel.

Memory configurations are also very different. The R7 M460 has 2 GB of GDDR5 on a 64-bit bus, delivering 36.00 GB/s of bandwidth at a memory clock of 1125 MHz (4.5 Gbps effective). The GTX 770M has 3 GB of GDDR5 on a 192-bit bus, delivering 96.19 GB/s of bandwidth at a memory clock of 1002 MHz (4 Gbps effective). The NVIDIA GPU has nearly three times the memory bandwidth, which is critical for compute workloads that move large data sets.

Rates and throughput numbers confirm the hierarchy. The R7 M460 achieves a pixel rate of 8.192 GPixel/s and a texture rate of 24.58 GTexel/s, with FP32 performance of 786.4 GFLOPS. The GTX 770M achieves 15.94 GPixel/s, 63.76 GTexel/s, and 1.530 TFLOPS of FP32. In every throughput metric, the NVIDIA part is roughly double or better.

The R7 M460 supports FP16 at the same rate as FP32 (786.4 GFLOPS, 1:1 ratio), while the GTX 770M does not list an FP16 figure. Both GPUs support DirectX 12, but the AMD part lists DirectX 12 (12_0) while the NVIDIA part lists DirectX 12 (11_0). Both support OpenGL 4.6, and both support Vulkan, with the AMD version at 1.2.170 and the NVIDIA version at 1.2.175.

The bus interfaces differ as well. The R7 M460 uses PCIe 3.0 x8, while the GTX 770M uses an MXM-B (3.0) interface. The NVIDIA part is a standard MXM module with a 75 W TDP and no power connectors, while the AMD part does not list a TDP or power connector requirements. The GTX 770M's display outputs are described as "Portable Device Dependent," reflecting its mobile module nature.

The Verdict

The recorded data points to a clear winner for compute performance. The NVIDIA GeForce GTX 770M beats the AMD Radeon R7 M460 by 22.7 percent in OpenCL, and it wins the only direct benchmark in the database. The hardware specifications support that outcome: more shading units, more TMUs, more ROPs, wider memory bus, and nearly triple the memory bandwidth.

The AMD Radeon R7 M460 is not without merit in its own context. It edges out the AMD Radeon HD 7730M by 0.5 percent, the Intel UHD Graphics P750 by 0.9 percent, and the NVIDIA GeForce GTX 670M by 1.5 percent in the broader database. Those are narrow wins against older or lower-tier parts. But against the GTX 770M, the R7 M460 cannot compete.

For anyone choosing between these two specific GPUs, the GTX 770M is the pick for OpenCL-based workloads, gaming, or any task that benefits from higher shader counts and memory bandwidth. The R7 M460 is a lightweight mobile part that sits near the 38th percentile of all GPUs, while the GTX 770M, despite its lower average score due to the Metal benchmark, delivers a much stronger OpenCL result.

The production status for both parts is end-of-life, so neither is a current purchase recommendation. But in a legacy system comparison, the GTX 770M is the superior GPU by every measured compute metric.
