AMD Radeon RX Vega M GH vs NVIDIA T600 Mobile Comparison

Head-to-Head Benchmarks

The benchmark data presents a split decision between these two mobile graphics processors. In the Geekbench OpenCL test, the NVIDIA T600 Mobile delivers a score of 35486, while the AMD Radeon RX Vega M GH records 27125. This gives NVIDIA a decisive 30.8% lead in compute workloads that favor OpenCL. The margin is substantial, not a marginal edge, and it positions the T600 clearly ahead in this specific API's raw throughput.

However, the Vulkan results flip the narrative. Here, the AMD Radeon RX Vega M GH scores 31268, edging out the NVIDIA T600 Mobile's 30211. The delta is a modest 3.4% in AMD's favor. This is a much tighter contest, suggesting that in Vulkan-optimized scenarios, the two GPUs are nearly peers, with AMD holding a slight advantage rather than a commanding one.

Looking at the broader context, the T600 Mobile's average benchmark score across all recorded tests is 32849, which places it at the 77th percentile of all GPUs in the database. Its nearest rivals include the NVIDIA P104-100 at 32982 (0.4% higher), the NVIDIA T550 Mobile at 33161 (0.9% higher), the AMD Radeon RX 590 GME at 32601 (0.8% lower), and the AMD FirePro S9300 X2 at 32540 (0.9% lower). The T600 sits in a tightly packed cluster, where a few percentage points separate it from its immediate competition.

The RX Vega M GH, by contrast, has an average benchmark score of 29197, landing at the 74th percentile. Its nearest rivals are the AMD FirePro W8000 at 29211 (essentially identical, 0% delta), the Intel Arc A370M at 29175 (0.1% lower), the AMD Radeon RX 470 at 28996 (0.7% lower), and the AMD Radeon RX 6800M at 28874 (1.1% lower). The AMD part sits in a similarly tight grouping, but at a lower absolute performance tier.

What is striking is the gap between the two averages: 32849 versus 29197, a difference of roughly 12.5% in favor of the NVIDIA part. Yet the head-to-head Vulkan result shows AMD winning. This implies the T600's advantage is heavily concentrated in OpenCL workloads, while Vulkan narrows the gap considerably. The data suggests NVIDIA's architecture has a stronger affinity for OpenCL's execution model, whereas AMD's GCN design holds its own in Vulkan's lower-level abstractions.

Architecture Differences

The two GPUs come from different architectural lineages. The NVIDIA T600 Mobile uses the TU117 chip, built on the Turing architecture, fabricated by TSMC on a 12 nm process. The AMD Radeon RX Vega M GH uses the Polaris 22 chip, based on GCN 4.0 architecture, manufactured by GlobalFoundries on a 14 nm node. The process difference is minor, but the architectural philosophies diverge significantly.

Transistor counts are close: the TU117 packs 4,700 million transistors on a 200 mm² die, yielding a transistor density of 23.5M per mm². The Polaris 22 contains 5,000 million transistors on a 208 mm² die, with a density of 24.0M per mm². Nearly identical silicon budgets, yet the internal designs distribute these resources differently.

The shading core counts tell a clear story. The AMD part fields 1536 shading units, 96 texture mapping units, and 64 render output units. The NVIDIA part has 896 shading units, 56 TMUs, and 32 ROPs. AMD has roughly 71% more shading units, 71% more TMUs, and double the ROPs. In theory, this should give AMD a raw throughput advantage, and indeed the pixel rate is 76.16 GPixel/s versus 45.12 GPixel/s, a 69% lead. Texture rate is 114.2 GTexel/s versus 78.96 GTexel/s, a 45% lead.

Yet the FP32 compute figures tell a more nuanced story. AMD records 3.656 TFLOPS, while NVIDIA records 2.527 TFLOPS. That is a 45% advantage for AMD in raw floating-point throughput. But the OpenCL benchmark shows NVIDIA winning by 30.8%. This is the central paradox of this comparison: AMD's theoretical compute advantage does not translate into OpenCL wins. The architecture's efficiency per FLOP, driver optimization, or API implementation details must be responsible.

Clock speeds differ notably. The AMD part has a base clock of 1063 MHz and a boost of 1190 MHz, while the NVIDIA part has a base of 780 MHz and a boost of 1410 MHz. The NVIDIA chip boosts much higher, which helps narrow the gap in some workloads despite fewer cores.

Memory configurations are radically different. The NVIDIA T600 uses 4 GB of GDDR6 on a 128-bit bus, with memory clocked at 1500 MHz (12 Gbps effective), yielding 192.0 GB/s of bandwidth. The AMD part uses 4 GB of HBM2 on a 1024-bit bus, with memory at 800 MHz (1600 Mbps effective), yielding 204.8 GB/s. The HBM2's wide bus gives AMD a modest 6.7% bandwidth advantage, but both have the same capacity.

The power envelope is a major differentiator. The T600 Mobile has a TDP of 40 W, while the RX Vega M GH has a TDP of 100 W. The AMD part consumes 2.5 times the power. This has profound implications for thermal management and battery life in portable devices, even though both are integrated graphics packages (IGP) with no dedicated power connectors.

API support shows subtle differences. NVIDIA supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. AMD supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The higher DirectX feature level and Vulkan version on the NVIDIA side could explain some benchmark differences.

The Verdict

The data paints a clear picture of two GPUs optimized for different priorities. The NVIDIA T600 Mobile wins the OpenCL benchmark decisively, offers a higher average benchmark score, sits at a higher percentile, supports newer API versions, and does all of this at a fraction of the power draw. The AMD Radeon RX Vega M GH wins only the Vulkan test, has a lower average score, and consumes 2.5 times the power.

For users whose workloads rely on OpenCL, the choice is unambiguous. The T600 Mobile's 30.8% lead in that test is a dominant margin. For Vulkan-centric applications, the AMD part's 3.4% edge is real but modest, and it comes at a severe power cost.

The NVIDIA part also benefits from a more recent release date and a documented successor, indicating an active product lineage. The AMD part has no predecessor or successor recorded, suggesting a more isolated design.

The production status for both is end-of-life, so neither is a forward-looking purchase. But among these two, the data favors the T600 Mobile for overall compute performance, efficiency, and API maturity.

Where Each One Wins

NVIDIA T600 Mobile wins in: OpenCL workloads, with a 30.8% score advantage. It also wins on overall average benchmark score (32849 versus 29197), percentile ranking (77th versus 74th), API support (DirectX 12_1 and Vulkan 1.4), power efficiency (40 W versus 100 W), and FP16 compute (5.053 TFLOPS versus 3.656 TFLOPS). Its higher boost clock of 1410 MHz suggests better single-threaded or lightly-threaded performance scaling.

AMD Radeon RX Vega M GH wins in: Vulkan workloads, with a 3.4% score advantage. It also wins on raw FP32 compute (3.656 TFLOPS), pixel rate (76.16 GPixel/s), texture rate (114.2 GTexel/s), shading units, TMUs, ROPs, memory bandwidth (204.8 GB/s), and memory bus width (1024 bit). Its higher base clock of 1063 MHz indicates better sustained low-load performance.

The split is clean: NVIDIA dominates efficiency and API-modern compute, while AMD dominates raw hardware specifications and Vulkan performance. The choice depends entirely on the target workload's API and power budget.
