GPU Comparison

NVIDIA T600 and AMD Radeon R7 M460 are both end-of-life mobile workstation and entry-level graphics solutions, but benchmark results place them in different performance tiers. The data shows a single head-to-head benchmark comparison, with the NVIDIA T600 delivering a decisive win over the AMD Radeon R7 M460 in OpenCL compute performance.

Head-to-Head Benchmarks

The only direct benchmark comparison available between these two GPUs is the Geekbench OpenCL test, and the results are heavily skewed toward the NVIDIA T600. The T600 scores 27,875 points, while the AMD Radeon R7 M460 scores 6,612 points. This translates to a delta of 321.6%, meaning the NVIDIA T600 is more than four times faster in this compute workload. To put that in perspective, the Radeon R7 M460’s score of 6,612 is roughly equivalent to the NVIDIA T600’s nearest rivals, which all sit in the 6,500–7,200 range. The T600, by contrast, is in a completely different class, averaging 7,035 across all its benchmark entries.

Looking at the broader benchmark suite for the NVIDIA T600, its average benchmark score is 7,035, which places it at the 39th percentile of all GPUs. Its nearest rivals include the NVIDIA GeForce GTX 970 (average score 7,157, delta -1.7%), the NVIDIA GeForce GTX 680M (7,023, delta 0.2%), and the AMD Radeon R5 M240 (6,975, delta 0.9%). The AMD Radeon R7 M460, on the other hand, has an average benchmark score of 6,612, placing it at the 38th percentile. Its closest competitors are the NVIDIA GeForce GT 1010 (6,698, delta -1.3%), the NVIDIA GeForce GTX 670M (6,513, delta 1.5%), and the Intel UHD Graphics P750 (6,554, delta 0.9%).

The T600 also shows strength across a range of DirectX tests. It scores 114 in Passmark DirectX 9, 49 in DirectX 11, 32 in DirectX 10, and 25 in DirectX 12. Its Passmark G3D score is 6,479, with a G2D score of 756 and a GPU compute score of 2,402. While the R7 M460 has no equivalent data for these tests, the OpenCL delta alone establishes a clear hierarchy: the T600 is the superior compute performer, while the R7 M460 sits near the bottom of the performance distribution.

Architecture Differences

The two GPUs come from different architectural generations and process nodes. The NVIDIA T600 is built on the Turing architecture, using the TU117 chip manufactured on a 12 nm process at TSMC. It packs 4,700 million transistors on a 200 mm² die, giving a transistor density of 23.5 million per mm². The AMD Radeon R7 M460 uses the older GCN 3.0 architecture, with the Meso chip fabricated on a 28 nm process, also at TSMC. It contains 1,550 million transistors on a 125 mm² die, resulting in a density of 12.4 million per mm². This means the T600 has roughly three times the transistor count and nearly double the die area, despite the smaller manufacturing node.

Memory configurations differ substantially. The T600 comes with 4 GB of GDDR6 memory on a 128-bit bus, delivering 160.0 GB/s of bandwidth. The R7 M460 has 2 GB of GDDR5 memory on a 64-bit bus, capping out at 36.00 GB/s. The T600’s memory clock is listed at 1250 MHz with 10 Gbps effective data rate, while the R7 M460 runs at 1125 MHz with 4.5 Gbps effective. This gives the T600 more than four times the memory bandwidth, which is critical for compute and texture-heavy workloads.

The compute resources also favor the T600. It has 640 shading units, 40 texture mapping units, and 32 ROPs. The R7 M460 has 384 shading units, 24 TMUs, and only 8 ROPs. Pixel rate for the T600 is 42.72 GPixel/s versus 8.192 GPixel/s for the R7 M460. Texture rate is 53.40 GTexel/s versus 24.58 GTexel/s. FP32 performance is 1.709 TFLOPS for the T600, while the R7 M460 manages 786.4 GFLOPS, less than half. The T600 also supports FP16 at 3.418 TFLOPS with a 2:1 ratio, whereas the R7 M460 offers FP16 at the same rate as FP32 (786.4 GFLOPS, 1:1).

API support differs slightly. The T600 supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The R7 M460 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The T600 also has a wider bus interface: PCIe 3.0 x16 versus PCIe 3.0 x8 on the R7 M460.

Where Each One Wins

The NVIDIA T600 wins in every measurable category where data exists. It dominates compute performance, as evidenced by the 321.6% lead in Geekbench OpenCL. It has superior memory capacity, type, and bandwidth. Its shading unit count, texture units, and ROPs are all higher. Its pixel rate and texture rate are dramatically better. Its FP32 and FP16 performance are both higher. It supports a newer DirectX feature level and a newer Vulkan version.

The AMD Radeon R7 M460 does not win any of the head-to-head benchmarks. However, in the context of its own nearest rivals, it holds its own, it is 1.5% ahead of the NVIDIA GeForce GTX 670M and 0.9% ahead of the Intel UHD Graphics P750. For older or less demanding workloads, the R7 M460 could be considered adequate, but the data does not show any scenario where it outperforms the T600.

The T600’s advantage is most pronounced in memory bandwidth and compute throughput. The 160.0 GB/s bandwidth versus 36.00 GB/s is a 4.4x gap, and the FP32 performance gap is 2.2x. These are the kinds of differences that matter in GPU compute tasks, rendering, and any workload that saturates memory.

The Verdict

The data is unambiguous: the NVIDIA T600 is the superior GPU across every metric available. Its Geekbench OpenCL score is 321.6% higher than the AMD Radeon R7 M460. Its average benchmark score of 7,035 versus 6,612 places it at a higher percentile (39th versus 38th). The T600 offers more memory, faster memory, more shading units, and higher clock speeds.

For users choosing between these two, the decision hinges on workload. The T600 is suited for tasks requiring compute performance, higher memory bandwidth, and modern API support like DirectX 12_1 and Vulkan 1.4. It is a workstation-oriented GPU with a 40 W TDP and single-slot design, making it appropriate for professional environments.

The R7 M460, by contrast, is a legacy mobile GPU with a 2016 release date. Its performance sits near the bottom of the distribution, with an average score of 6,612. It is best matched against other older entry-level parts like the GTX 670M or HD 7730M. For any modern workload, the T600 is the clear choice based on the data available.
