NVIDIA GeForce RTX 5070 Mobile vs NVIDIA T600 Mobile Comparison

The Verdict

The data is unambiguous: the NVIDIA GeForce RTX 5070 Mobile is in a completely different performance class than the NVIDIA T600 Mobile. Across the two shared benchmark tests, the RTX 5070 Mobile wins both, with the T600 Mobile trailing by 71% in Geekbench OpenCL and 74.2% in Geekbench Vulkan. For any workload where raw compute throughput matters, the RTX 5070 Mobile is the only rational choice.

The T600 Mobile, however, retains a narrow niche. Its average benchmark score of 32,849 places it at the 77th percentile of all GPUs, which is actually higher than the RTX 5070 Mobile's 75th percentile. This is because the RTX 5070 Mobile's average score of 29,928 is dragged down by its Passmark DirectX 10, 11, and 12 results, which are low relative to its OpenCL and Vulkan performance. The T600 Mobile also consumes less power, with a 40 W TDP versus 50 W for the RTX 5070 Mobile, making it a fit for ultra-low-power mobile designs where the RTX 5070 Mobile's higher draw is unacceptable.

Who should pick which: if the workload is modern compute, gaming, or any DirectX 12 Ultimate feature set, the RTX 5070 Mobile is the clear winner. If the requirement is a legacy-compatible, low-power GPU for basic display and light compute in a thin-and-light chassis, the T600 Mobile remains viable, but it is end-of-life and offers roughly a quarter of the RTX 5070 Mobile's raw throughput in the two benchmarks where both were measured.

Architecture Differences

The two GPUs are separated by two full architecture generations. The T600 Mobile uses the TU117 chip on the Turing architecture, built on a 12 nm process at TSMC. It packs 4,700 million transistors into a 200 mm² die, for a transistor density of 23.5 million per square millimeter. The RTX 5070 Mobile uses the GB206 chip on the Blackwell 2.0 architecture, built on a 5 nm process, also at TSMC. It integrates 21,900 million transistors into a smaller 181 mm² die, yielding 121.0 million transistors per square millimeter. That is a 5.1x improvement in density, enabled by the two-generation process jump.

Core counts differ dramatically. The T600 Mobile has 896 shading units, 56 texture mapping units, and 32 raster operation pipelines. It has no dedicated ray tracing cores and no tensor cores. The RTX 5070 Mobile has 4,608 shading units (5.1x more), 144 TMUs (2.6x more), and 48 ROPs (1.5x more). It also includes 36 ray tracing cores and 144 tensor cores, features entirely absent from the T600 Mobile.

Memory subsystem differences are equally stark. The T600 Mobile uses 4 GB of GDDR6 on a 128-bit bus, delivering 192.0 GB/s of bandwidth. The RTX 5070 Mobile uses 8 GB of GDDR7 on the same 128-bit bus, doubling capacity and delivering 384.0 GB/s, exactly twice the bandwidth. Both run their memory at 1500 MHz, but the effective data rate is 12 Gbps for GDDR6 versus 24 Gbps for GDDR7.

The bus interface also differs: the T600 Mobile uses PCIe 3.0 x16, while the RTX 5070 Mobile uses PCIe 5.0 x16. Both are integrated into the motherboard (IGP slot width) with no power connectors and portable-device-dependent display outputs. API support favors the newer card: the RTX 5070 Mobile supports DirectX 12 Ultimate (12_2), while the T600 Mobile caps at DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

Head-to-Head Benchmarks

The two GPUs were measured in exactly two shared tests: Geekbench OpenCL and Geekbench Vulkan. In both, the RTX 5070 Mobile wins by a massive margin.

In Geekbench OpenCL, the T600 Mobile scores 35,486 while the RTX 5070 Mobile scores 122,238. That is a 71% advantage for the newer card, meaning the RTX 5070 Mobile delivers roughly 3.4x the OpenCL performance. In Geekbench Vulkan, the T600 Mobile scores 30,211 versus 116,960 for the RTX 5070 Mobile, a 74.2% delta and again roughly 3.9x the performance.

These are the only direct comparisons available in the database. The RTX 5070 Mobile also has additional benchmark coverage that the T600 Mobile lacks entirely: Passmark DirectX 10 (129), DirectX 11 (192), DirectX 12 (93), DirectX 9 (214), G2D (896), G3D (20,355), and GPU compute (8,279). The T600 Mobile has no Passmark entries at all, so no cross-format comparison is possible for those tests.

The average benchmark scores tell a more complicated story. The T600 Mobile's average is 32,849, while the RTX 5070 Mobile's is 29,928. The RTX 5070 Mobile's low Passmark DirectX scores (93 to 214) pull its average down despite its dominant OpenCL and Vulkan results. This is why the T600 Mobile sits at the 77th percentile of all GPUs while the RTX 5070 Mobile sits at the 75th, despite being wildly faster in the two shared workloads.

Where Each One Wins

The RTX 5070 Mobile wins in every workload where performance matters. Its OpenCL score of 122,238 and Vulkan score of 116,960 dwarf the T600 Mobile's 35,486 and 30,211 respectively. It has 5.1x the shading units, 2.6x the texture units, and 1.5x the raster operations pipelines. It doubles memory capacity to 8 GB, doubles bandwidth to 384.0 GB/s, and adds ray tracing and tensor core support. Its 13.13 TFLOPS FP32 throughput is more than 5x the T600 Mobile's 2.527 TFLOPS. Its FP16 performance is 13.13 TFLOPS at 1:1 ratio, versus 5.053 TFLOPS at 2:1 for the T600 Mobile. For any compute-heavy, modern API workload, the RTX 5070 Mobile is the definitive choice.

The T600 Mobile wins in exactly two categories: power draw and percentile ranking. At 40 W versus 50 W, it consumes 20% less power. Its 77th percentile ranking versus 75th is a statistical artifact of the RTX 5070 Mobile's weak Passmark DirectX scores, not a sign of real-world superiority. The T600 Mobile also carries a smaller transistor count (4,700 million versus 21,900 million) and a larger die (200 mm² versus 181 mm²), but those are architectural facts, not advantages. The only genuine use case for the T600 Mobile is an ultra-low-power, end-of-life mobile platform where the RTX 5070 Mobile's 50 W TDP and newer feature set are not required.
