AMD Radeon R9 M375X vs NVIDIA T600 Comparison

# Head-to-Head Benchmarks

The benchmark data paints a stark picture for the AMD Radeon R9 M375X when placed against the NVIDIA T600. Across the two recorded head-to-head tests, the T600 dominates decisively, leaving the older AMD mobile part trailing by a massive margin in both OpenCL and Vulkan workloads.

In the Geekbench OpenCL test, the NVIDIA T600 scores 27,875 points, while the AMD Radeon R9 M375X manages just 8,273 points. That represents a 70.3% deficit for the AMD card, meaning the T600 delivers more than three times the raw compute throughput in this particular workload. The gap is not a marginal one, it is a generational chasm.

The Vulkan results tell a similar story, though the margin narrows slightly. The T600 posts 25,580 points against the R9 M375X's 8,377 points, a 67.3% difference in favor of the NVIDIA card. While Vulkan is a lower-level API that can sometimes benefit older architectures through more direct hardware access, the Turing-based T600 still cruises to an overwhelming victory here.

With wins tallying at 2 for the T600 and 0 for the R9 M375X, the head-to-head record is one-sided. The data shows no test where the AMD part even approaches parity, let alone claims a win. For the R9 M375X, the best result is still less than a third of what the T600 achieves in its weaker benchmark.

Looking at the broader database context, the R9 M375X sits at the 43rd percentile among all GPUs, with an average benchmark score of 8,325 points. Its nearest rivals include the NVIDIA Quadro K1200 at 8,265 points (a 0.7% gap in favor of the AMD card), the GeForce GTX 675MX at 8,427 points (1.2% ahead), and the AMD Radeon 880M at 8,436 points (1.3% ahead). These are tight margins, indicating the R9 M375X is competitive with its immediate peers from its era.

The NVIDIA T600, by contrast, holds the 39th percentile overall with an average score of 7,035 points. That percentile ranking might seem odd given its head-to-head dominance, but the T600's average is dragged down by its Passmark scores, which include a DirectX 9 result of 114, a DirectX 10 result of 32, and a DirectX 11 result of 49. These legacy API tests are not flattering to the Turing architecture, which prioritizes modern workloads. Its direct rivals include the GeForce GTX 680M at 7,023 points (0.2% behind), the Radeon R5 M240 at 6,975 points (0.9% behind), and the GeForce GTX 970 at 7,157 points (1.7% ahead).

The takeaway is clear: in modern compute-centric benchmarks, the T600 is in a different league entirely. The R9 M375X's best hope lies in older DirectX-based workloads where its GCN 1.0 architecture retains some relevance, but even there, the data does not suggest any outright wins.

# Architecture Differences

The two GPUs come from vastly different eras and design philosophies. The AMD Radeon R9 M375X is built on the GCN 1.0 architecture, using the Tropo chip, and belongs to the Gem System generation of the R9 M300 series. It was released in May 2015 and has reached end-of-life status. The NVIDIA T600, meanwhile, employs the Turing architecture with the TU117 chip, part of the Quadro Turing Tx000 generation, and launched in April 2021. It too is now end-of-life.

The manufacturing process tells part of the story. The R9 M375X uses a 28 nm process node at TSMC, while the T600 is fabricated on a 12 nm process, also at TSMC. That process shrink allows for substantially higher transistor density: the T600 packs 4,700 million transistors into a 200 mm² die, yielding 23.5 million transistors per square millimeter. The R9 M375X contains just 1,500 million transistors on a 123 mm² die, for a density of 12.2 million per square millimeter. In absolute terms, the T600 has over three times the transistor count of the AMD part.

Memory configurations diverge significantly. The R9 M375X comes with 2 GB of GDDR5 memory on a 128-bit bus, delivering 72.00 GB/s of bandwidth. The T600 doubles the capacity to 4 GB and upgrades to GDDR6, also on a 128-bit bus, but with more than double the bandwidth at 160.0 GB/s. Clock speeds also favor the newer card: the T600 boosts to 1,335 MHz from a 735 MHz base, while the R9 M375X boosts to 1,015 MHz from 925 MHz. Memory clocks show the generational leap too, with the T600 running at 10 Gbps effective versus 4.5 Gbps for the AMD part.

Compute resources are more evenly matched in some respects. Both cards feature 640 shading units and 40 texture mapping units. The ROP count differs, however, with the R9 M375X offering 16 ROPs while the T600 doubles that to 32. This explains the pixel rate gap: the T600 achieves 42.72 GPixel/s against the R9 M375X's 16.24 GPixel/s. Texture rate also favors NVIDIA, at 53.40 GTexel/s versus 40.60 GTexel/s.

Floating-point performance shows the T600's advantage. The NVIDIA card delivers 1.709 TFLOPS of FP32 compute, while the R9 M375X manages 1,299.2 GFLOPS. The T600 additionally supports FP16 at 3.418 TFLOPS with a 2:1 ratio, a feature the AMD part lacks entirely in the recorded data.

API support differs in notable ways. The R9 M375X supports DirectX 12 at the 11_1 feature level, OpenGL 4.6, and Vulkan 1.2.170. The T600 supports DirectX 12 at the 12_1 feature level, OpenGL 4.6, and Vulkan 1.4. The newer Vulkan version and higher DirectX feature level give the T600 a software compatibility edge.

Power characteristics are only recorded for the T600, which lists a 40 W TDP, a single-slot form factor, no power connectors, and a suggested 200 W power supply. The R9 M375X has no TDP or power data in the database. Display outputs are likewise only specified for the T600, which offers 4x mini-DisplayPort 1.4a.

# Where Each One Wins

The NVIDIA T600 is the clear winner in modern compute benchmarks. Its Geekbench OpenCL score of 27,875 and Vulkan score of 25,580 place it far beyond the reach of the R9 M375X. The T600's advantage stems from its Turing architecture, higher boost clock of 1,335 MHz, doubled ROP count, and significantly faster GDDR6 memory at 160.0 GB/s. For users running compute-heavy applications that leverage OpenCL or Vulkan, the T600 is the only sensible choice between these two.

The T600 also wins on capacity and connectivity. Its 4 GB of VRAM doubles the R9 M375X's 2 GB, and its four mini-DisplayPort 1.4a outputs provide professional-grade multi-monitor flexibility. The single-slot form factor, 40 W TDP, and lack of power connectors make it far easier to integrate into workstation builds.

The AMD Radeon R9 M375X does not win any recorded benchmark against the T600. Its wins, if any, would have to come in scenarios not captured by the head-to-head data. The R9 M375X's nearest rival comparisons show it is competitive with its own generation, sitting within 1.6% of the GeForce MX330 and 1.3% of the Radeon 880M. For legacy applications that are optimized for GCN 1.0's specific feature set, particularly older DirectX titles, the R9 M375X might hold its own among peers from 2015.

However, the R9 M375X's DirectX 12 (11_1) feature level limits its compatibility with the latest game and application requirements. The T600's DirectX 12 (12_1) support and Vulkan 1.4 ensure better forward compatibility. The R9 M375X also lacks FP16 support, which is increasingly relevant in AI and compute workloads, while the T600 offers 3.418 TFLOPS of FP16 performance.

In practical terms, the T600 is the better card for virtually any workload using modern APIs. The R9 M375X's only potential advantage lies in its lower transistor count and smaller die, which historically could translate to lower power draw, but no TDP data exists for the AMD part to confirm this. The database shows a 2-0 victory for the T600, with margins of 70.3% and 67.3% that leave no room for ambiguity.
