GPU Comparison

Head-to-Head Benchmarks

The head-to-head data presents a split decision that mirrors the fundamentally different design goals of these two GPUs. The NVIDIA T600 Mobile wins the Geekbench OpenCL test, while the AMD Radeon RX 6800 dominates the Vulkan test. The margins in each case are substantial, but the direction of the wins tells the more important story.

In Geekbench OpenCL, the NVIDIA T600 Mobile scores 35486 against the AMD Radeon RX 6800's 24508. That is a 44.8% advantage for the NVIDIA part. This is a significant margin in a compute-oriented API and suggests that the T600 Mobile's architecture is highly optimized for the specific workload patterns that OpenCL benchmarking exercises. The T600 Mobile's average benchmark score across all recorded tests is 32849, which places it in the 77th percentile of all GPUs in the database. Its nearest rivals include the NVIDIA P104-100 at 32982 (0.4% lower), the AMD Radeon RX 590 GME at 32601 (0.8% lower), and the AMD FirePro S9300 X2 at 32540 (0.9% lower). The T600 Mobile sits just below the NVIDIA T550 Mobile, which scores 33161 and is 0.9% higher.

The Vulkan result is a complete reversal. The AMD Radeon RX 6800 scores 115107 in Geekbench Vulkan, while the NVIDIA T600 Mobile manages only 30211. The delta is 73.8% in favor of AMD. This is a massive gap, and it reflects both the raw compute advantage of the RX 6800 and the efficiency of its RDNA 2.0 architecture in modern graphics APIs. The RX 6800's average benchmark score is 30095, putting it in the 75th percentile of all GPUs. Its nearest rivals are the AMD Radeon RX 6700 at 30433 (1.1% higher), the NVIDIA GeForce RTX 3070 Ti at 29945 (0.5% lower), the NVIDIA GeForce RTX 5070 Mobile at 29928 (0.6% lower), and the NVIDIA GeForce RTX 2080 Ti at 29783 (1.0% lower). The Vulkan margin between the two cards in this comparison is far larger than the gaps between either card and its nearest rivals, which underscores how differently these architectures behave across APIs.

The broader benchmark suite for the RX 6800 includes results that the T600 Mobile simply does not have recorded. In Passmark G3D, the RX 6800 scores 22067. In Passmark GPU Compute, it scores 10864. In Geekbench Metal, it scores 153635. The RX 6800 also has 3DMark Steel Nomad DX12 results at 3188 and a range of Passmark DirectX tests: 257 in DirectX 9, 214 in DirectX 11, 128 in DirectX 10, and 89 in DirectX 12. The T600 Mobile has no equivalent records in these tests, so a direct comparison is not possible from the database, but the recorded scores for the RX 6800 demonstrate consistent performance across multiple benchmarking methodologies.

Architecture Differences

The two GPUs are built on entirely different architectures, nodes, and design philosophies. The NVIDIA T600 Mobile uses the TU117 chip based on the Turing architecture, fabricated by TSMC on a 12 nm process. It integrates 4,700 million transistors on a 200 mm² die, yielding a transistor density of 23.5 million per mm². The AMD Radeon RX 6800 uses the Navi 21 chip based on RDNA 2.0, also fabricated by TSMC but on a 7 nm process. It packs 26,800 million transistors on a 520 mm² die, with a transistor density of 51.5 million per mm². The RX 6800 has more than five times the transistor count of the T600 Mobile, and roughly 2.6 times the die area, but its 7 nm node allows for a much higher density of transistors per square millimeter.

The compute resources differ by a wide margin. The T600 Mobile has 896 shading units, 56 texture mapping units, and 32 raster output pipelines. The RX 6800 has 3840 shading units, 240 TMUs, and 96 ROPs. That is roughly 4.3 times the shading units, 4.3 times the TMUs, and 3 times the ROPs. The RX 6800 also includes 60 ray tracing cores, while the T600 Mobile has no ray tracing cores at all. Neither card has tensor cores listed in the database.

Clock speeds are also very different. The T600 Mobile has a base clock of 780 MHz and a boost clock of 1410 MHz. The RX 6800 has a base clock of 1700 MHz, a game clock of 1815 MHz, and a boost clock of 2105 MHz. The AMD part runs at more than double the base clock and roughly 50% higher boost clock. The memory subsystems are equally divergent. The T600 Mobile has 4 GB of GDDR6 on a 128 bit bus, with 1500 MHz memory clock and 12 Gbps effective speed, producing 192.0 GB/s of bandwidth. The RX 6800 has 16 GB of GDDR6 on a 256 bit bus, with 2000 MHz memory clock and 16 Gbps effective speed, producing 512.0 GB/s of bandwidth. The RX 6800 has four times the memory capacity and roughly 2.7 times the bandwidth.

The resulting fill rates and compute throughput reflect these differences. The T600 Mobile delivers 45.12 GPixel/s pixel rate and 78.96 GTexel/s texture rate, with 2.527 TFLOPS FP32 and 5.053 TFLOPS FP16. The RX 6800 delivers 202.1 GPixel/s pixel rate and 505.2 GTexel/s texture rate, with 16.17 TFLOPS FP32 and 32.33 TFLOPS FP16. The RX 6800 is roughly 4.5 times faster in pixel throughput, 6.4 times faster in texture throughput, and 6.4 times faster in FP32 compute.

Power and physical design also separate them. The T600 Mobile has a TDP of 40 W, is an IGP form factor, requires no power connectors, and uses a PCIe 3.0 x16 interface. The RX 6800 has a TDP of 250 W, is a dual-slot card, requires 2x 8-pin power connectors and a suggested 600 W power supply, and uses a PCIe 4.0 x16 interface. The RX 6800 has physical dimensions of 267 mm length, 120 mm height, and 40 mm width. The T600 Mobile lists no physical dimensions in the database. The display outputs also differ: the T600 Mobile is described as portable device dependent, while the RX 6800 offers 1x HDMI 2.1, 2x DisplayPort 1.4a, and 1x USB Type-C.

Both cards support DirectX 12 and OpenGL 4.6 and Vulkan 1.4, but the RX 6800 supports DirectX 12 Ultimate (12_2) while the T600 Mobile is limited to DirectX 12 (12_1). The RX 6800 is part of the Radeon RX 6000 series, in the Navi II generation, while the T600 Mobile belongs to the Quadro Turing-M generation. The RX 6800 was released on 2020-10-27 and its predecessor is listed as Navi. The T600 Mobile was released on 2021-04-11, with its predecessor listed as Quadro Pascal-M. Both are now end-of-life products.

Where Each One Wins

The NVIDIA T600 Mobile wins in Geekbench OpenCL by 44.8%, and its average benchmark score of 32849 is higher than the RX 6800's 30095. It also consumes dramatically less power at 40 W versus 250 W, needs no power connectors, and comes in an IGP form factor. For workloads that rely on OpenCL compute performance and where power draw or physical space is constrained, the T600 Mobile has a clear case. Its nearest rivals in the database are all within roughly 1% of its average score, meaning it sits in a tightly competitive cluster of mid-range GPUs, but in the direct head-to-head OpenCL comparison, it is decisively ahead of the RX 6800.

The AMD Radeon RX 6800 wins Geekbench Vulkan by 73.8%, and its 115107 Vulkan score dwarfs the T600 Mobile's 30211. It also has far more compute resources: 3840 shading units versus 896, 240 TMUs versus 16, and 96 ROPs versus 32. It has 60 ray tracing cores, which the T600 Mobile lacks entirely. Its 16 GB memory capacity is four times larger, and its 512.0 GB/s bandwidth is roughly 2.7 times higher. Its FP32 compute of 16.17 TFLOPS is roughly 6.4 times higher than the T600 Mobile's 2.527 TFLOPS. In Passmark G3D and GPU Compute scores of 22067 and 10864, plus the Geekbench Metal score of 153635, further demonstrate its strength across a wider range of benchmark methodologies where the T600 Mobile has no recorded results.

The RX 6800 also supports DirectX 12 Ultimate, while the T600 Mobile is limited to DirectX 12 (12_1). The RX 6800's 7 nm process and 51.5M / mm² density versus the T600 Mobile's 12 nm process and 23.5M / mm² density reflect a generational leap in manufacturing efficiency. The RX 6800's 202.1 GPixel/s pixel rate and 505.2 GTexel/s texture rate are far above the T600 Mobile's 45.12 GPixel/s and 78.96 GTexel/s. For any workload that stresses Vulkan, modern DirectX, ray tracing, or high-resolution textures, the RX 6800 is the clear choice based on the recorded data.

The Verdict

The data presents two very different products aimed at two very different use cases. The NVIDIA T600 Mobile is a low-power IGP with a 40 W TDP, no power connectors, and a portable device dependent display output. It wins OpenCL by a large margin and has a higher average benchmark score. It is the choice for environments where power efficiency, compact form factor, and OpenCL compute are the priorities. Its end-of-life status and 4 GB memory capacity limit its long-term relevance for demanding workloads, but within its niche, the benchmark data supports it.

The AMD Radeon RX 6800 is a full-size dual-slot card with a 250 W TDP, 2x 8-pin power connectors, and a suggested 600 W PSU. It wins Vulkan by a massive 73.8% margin, has 60 ray tracing cores, 16 GB of memory, 512.0 GB/s of bandwidth, and 16.16 TFLOPS of FP32 compute. It supports PCIe 4.0 x16 and DirectX 12 Ultimate. The launch MSRP is 579 USD. For gaming, ray tracing, high-bandwidth memory workloads, and modern API performance, the RX 6800 has the recorded data on its side, despite a lower average benchmark score and a lower percentile ranking at 75.

The split decision in the head-to-head benchmarks, 1 win for the T600 Mobile and 1 win for the RX 6800, means that neither card cannot be declared an overall winner. Instead, the verdict depends entirely on the intended workload. OpenCL-centric users should favor the T600 Mobile. Vulkan-centric users should favor the RX 6800. Given the scale of the RX 6800's compute advantages and the breadth of its benchmark coverage, users who need a general-purpose high-performance GPU should pick the RX 6800, while users who need a power-lean compute accelerator in a constrained chassis should pick the T600 Mobile.
