AMD Radeon RX 7900 GRE vs NVIDIA T600 Mobile Comparison

The NVIDIA T600 Mobile and AMD Radeon RX 7900 GRE occupy opposite ends of the GPU spectrum, and the benchmark data reflects a complete separation of purpose. The T600 Mobile is an end-of-life, 40 W integrated-class part built for the Quadro Turing-M generation, while the RX 7900 GRE is an active, 260 W dual-slot monster from the Radeon RX 7000 series. In the two head-to-head benchmarks available, the AMD card wins both decisively, yet the T600 Mobile still holds a 77th percentile rank among all GPUs, identical to the RX 7900 GRE's percentile, showing that raw score is not the only measure of placement. This analysis breaks down where each card wins, what separates their architectures, and which user profile each serves based strictly on the provided facts.

Where Each One Wins

The AMD Radeon RX 7900 GRE wins every head-to-head benchmark in the data set, but the nature of those wins reveals its dominance is not uniform. In Geekbench OpenCL, the RX 7900 GRE scores 175,758 against the T600 Mobile's 35,486, a delta of -79.8% from the AMD card's perspective, meaning the T600 Mobile trails by nearly five times. In Geekbench Vulkan, the gap narrows slightly in relative terms: the RX 7900 GRE posts 99,850 versus 30,211, a -69.7% delta. The AMD card's compute advantage is staggering, but the Vulkan result shows the T600 Mobile's Turing architecture holds up better in API-specific workloads than in raw OpenCL compute.

The T600 Mobile's wins are not in performance but in efficiency and form factor. With a 40 W TDP, no power connectors, and an IGP slot width, it is designed for portable devices where the RX 7900 GRE's 260 W TDP, dual-slot footprint, and 2x 8-pin connectors are physically impossible. The T600 Mobile also uses PCIe 3.0 x16, while the RX 7900 GRE uses PCIe 4.0 x16, but the T600 Mobile's lower bandwidth requirements make its older interface adequate. For any workload that fits within 4 GB of GDDR6 memory and a 192.0 GB/s bandwidth, the T600 Mobile provides a functional path; for anything beyond that, the RX 7900 GRE's 16 GB and 576.0 GB/s are the only option.

Architecture Differences

The two GPUs share a foundry—TSMC—but little else. The T600 Mobile uses the TU117 chip on a 12 nm process, packing 4,700 million transistors into a 200 mm² die. The RX 7900 GRE uses the Navi 31 chip on a 5 nm process, with 57,700 million transistors across a 529 mm² die. The transistor density tells the story: the RX 7900 GRE achieves 109.1M transistors per mm² versus the T600 Mobile's 23.5M per mm², a 4.6x density advantage that reflects the generational leap in manufacturing.

The architecture generations are equally divergent. The T600 Mobile is Turing, a 2018-era design focused on professional Quadro workloads, while the RX 7900 GRE is RDNA 3.0, AMD's latest gaming-first architecture. The T600 Mobile has no ray tracing cores and no tensor cores—both fields are null in the data—while the RX 7900 GRE includes 80 ray tracing cores. The RX 7900 GRE also supports DirectX 12 Ultimate (12_2), while the T600 Mobile is limited to DirectX 12 (12_1), a difference that matters for modern game features but not for the professional applications the T600 Mobile targets. Both support OpenGL 4.6 and Vulkan 1.4, so API-level compatibility is otherwise identical.

The memory subsystems are worlds apart. The T600 Mobile has 4 GB GDDR6 on a 128-bit bus, yielding 192.0 GB/s. The RX 7900 GRE has 16 GB GDDR6 on a 256-bit bus, yielding 576.0 GB/s—exactly three times the bandwidth. The RX 7900 GRE also runs its memory at 2250 MHz (18 Gbps effective) versus the T600 Mobile's 1500 MHz (12 Gbps effective). The shading resources scale accordingly: the RX 7900 GRE has 5,120 shading units, 320 TMUs, and 160 ROPs, against the T600 Mobile's 896, 56, and 32. The RX 7900 GRE's pixel rate of 359.2 GPixel/s is nearly 8x the T600 Mobile's 45.12 GPixel/s, and its texture rate of 718.4 GTexel/s is over 9x the T600 Mobile's 78.96 GTexel/s.

Head-to-Head Benchmarks

The Geekbench OpenCL test is the clearest demonstration of the performance gap. The RX 7900 GRE's score of 175,758 is 140,272 points higher than the T600 Mobile's 35,486, a 79.8% deficit for the NVIDIA card. This is not a marginal difference; it is a generational chasm. The RX 7900 GRE's FP32 throughput of 45.98 TFLOPS against the T600 Mobile's 2.527 TFLOPS—an 18.2x difference—explains the OpenCL result, as does the AMD card's 16 GB frame buffer, which allows far larger compute workloads to reside on-card.

The Geekbench Vulkan result is more nuanced. The RX 7900 GRE scores 99,850, which is 69,639 points above the T600 Mobile's 30,211, a 69.7% delta. The absolute gap is smaller than in OpenCL, and the percentage gap is also tighter, suggesting that the T600 Mobile's Turing architecture is relatively more efficient in Vulkan than in OpenCL. Still, the RX 7900 GRE's 5,120 shading units and 80 ray tracing cores provide a massive hardware advantage that no driver optimization can overcome. The T600 Mobile's FP16 throughput of 5.053 TFLOPS (2:1) is respectable for its class, but the RX 7900 GRE's 91.96 TFLOPS (2:1) is 18.2x higher, making the AMD card the clear choice for any compute-heavy Vulkan workload.

The RX 7900 GRE also has additional benchmark data not available for the T600 Mobile, including PassMark scores. Its PassMark G3D score is 27,089, and its GPU compute score is 15,016, with DirectX 11 (300) and DirectX 9 (310) scores leading its DirectX 12 (107) and DirectX 10 (139) results. These figures are context for the RX 7900 GRE's overall capability, but they do not directly compare to the T600 Mobile, which has no PassMark entries.

The Verdict

The data paints a clear picture: the AMD Radeon RX 7900 GRE is the superior performer in every measured benchmark, and the only user who should pick the NVIDIA T600 Mobile is one constrained by power, space, or portability. The RX 7900 GRE's 175,758 OpenCL and 99,850 Vulkan scores dwarf the T600 Mobile's 35,486 and 30,211, respectively, and its 45.98 TFLOPS FP32 throughput is 18.2x higher. For gaming, compute, or any GPU-accelerated workload where performance matters, the RX 7900 GRE is the only rational choice.

However, the T600 Mobile's 40 W TDP, IGP slot width, and lack of power connectors make it the only option for thin-and-light portable devices. Its 4 GB memory and 192.0 GB/s bandwidth are sufficient for professional Quadro-class tasks that do not require large frame buffers, and its 77th percentile rank shows it performs well within its class. The RX 7900 GRE, by contrast, demands a 600 W PSU, a dual-slot chassis, and a 276 mm length, making it unsuitable for any compact build.

The 77th percentile for both GPUs is a statistical curiosity: despite the massive performance gap, both sit at the same percentile vs. all GPUs, indicating that the benchmark database's percentile calculation weights factors beyond raw compute, or that the T600 Mobile's efficiency and T550-class rivals (NVIDIA T550 Mobile at 33,161 avg score, -0.9% delta) keep it in the same tier. In practice, the choice is clear: the RX 7900 GRE for desktop performance, the T600 Mobile for mobile efficiency. The data does not support any other conclusion.
