AMD Radeon RX 6800 vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

Head-to-Head Benchmarks

The head-to-head data presents a lopsided contest. The NVIDIA GeForce RTX 5070 Ti Mobile wins 7 of the 9 recorded comparisons, and it does so with some dramatic margins. The most striking result is in Geekbench OpenCL, where the RTX 5070 Ti Mobile scores 143,870 against 24,508 for the Radeon RX 6800. That is a 487% advantage, the single largest delta in the entire comparison. Such a wide gap in a compute-oriented workload suggests the newer architecture is handling the test with fundamentally different efficiency.

The Vulkan results are closer but still favor NVIDIA. The RTX 5070 Ti Mobile records 139,213, while the RX 6800 manages 115,107, a 20.9% lead. This is a meaningful margin in a modern graphics API, and it aligns with the pattern seen in the Passmark DirectX tests. In DirectX 10, NVIDIA wins 151 to 128, an 18% edge. DirectX 12 shows 102 versus 89, a 14.6% advantage. DirectX 11 is tighter at 237 versus 214, a 10.7% gap. The oldest API tested, DirectX 9, is nearly a tie: 259 against 257, a 0.8% delta that is effectively noise.

The 3D gaming-oriented Passmark G3D test also goes to NVIDIA, with 24,004 versus 22,067, an 8.8% win. That is a solid but not overwhelming performance advantage in a rasterization-heavy workload. The data implies the RTX 5070 Ti Mobile is consistently ahead across most graphics workloads, but the size of the lead varies considerably depending on the test.

AMD does claim two victories. The Passmark G2D test, which measures 2D and basic desktop performance, goes to the RX 6800 by a hair: 990 versus 981, a 0.9% margin. This is a minor win, but it does show the AMD card is not completely outclassed in every scenario. The more significant AMD victory comes in Passmark GPU Compute, where the RX 6800 scores 10,864 against 10,101 for the NVIDIA part, a 7% advantage. This is notable because it shows the older AMD card has a genuine strength in certain compute workloads, even as it loses decisively in the Geekbench OpenCL test.

Looking at the broader benchmark averages, the RTX 5070 Ti Mobile holds an average score of 35,435 across all recorded tests, while the RX 6800 sits at 30,095. That is a sizable overall gap. The percentile rankings reinforce this: the NVIDIA part sits at the 80th percentile of all GPUs in the database, while the AMD card is at the 75th. Neither is a top-tier flagship, but the NVIDIA mobile part is clearly a step above the older AMD desktop card in aggregate performance.

The nearest rivals for each card provide context. The RTX 5070 Ti Mobile sits within 2.4% of the NVIDIA T1000 (which scores 36,289) and within 2.1% of the NVIDIA A2 (34,690). It also trails the AMD Radeon Pro Duo by 1.2% and the NVIDIA Quadro GV100 by 0.2%. These are all close scores, meaning the RTX 5070 Ti Mobile is competing with professional and workstation-class parts from a generation or two ago. The RX 6800, meanwhile, sits within 1.1% of the AMD Radeon RX 6700 (30,433) and within 1% of the NVIDIA GeForce RTX 2080 Ti (29,783). It edges out the RTX 3070 Ti (29,945) by 0.5% and the RTX 5070 Mobile (29,928) by 0.6%. This suggests the RX 6800 is still a capable performer, roughly on par with mid-range to upper-mid-range cards from recent generations.

The Verdict

The data points to a clear choice for most users. If the priority is raw graphics performance across modern APIs, the NVIDIA GeForce RTX 5070 Ti Mobile is the stronger option. It wins the G3D test by 8.8%, the Vulkan test by 20.9%, and the DirectX 12 test by 14.6%. It also has a commanding lead in OpenCL compute, which could matter for applications that leverage that API.

The Radeon RX 6800, however, is not without its own case. It wins the GPU Compute benchmark by 7%, which indicates a real advantage in certain compute-heavy tasks. Its win in G2D, while tiny, shows it handles desktop workloads just fine. For a user whose primary workload is compute-oriented and specifically benefits from the RX 6800's strengths, the AMD card could be the better pick.

From the recorded data, the RTX 5070 Ti Mobile is the better all-around performer. Its 80th percentile ranking versus the RX 6800's 75th percentile reinforces this. The NVIDIA part is also currently in active production, while the AMD card is listed as end-of-life. The AMD card does have twice the memory capacity, 16 GB versus 12 GB, which could matter for certain large datasets or texture-heavy workloads, but the benchmark scores do not show that capacity translating into a consistent performance advantage.

Architecture Differences

The two GPUs come from different architectural lineages. The NVIDIA GeForce RTX 5070 Ti Mobile uses the Blackwell 2.0 architecture on the GB205 chip, built on a 5 nm process at TSMC. The AMD Radeon RX 6800 uses the RDNA 2.0 architecture on the Navi 21 chip, built on a 7 nm process, also at TSMC. The process node difference is significant: the NVIDIA part uses a more advanced fabrication process, which likely contributes to its efficiency advantages.

The transistor counts tell an interesting story. The NVIDIA chip packs 31,100 million transistors into a die size of 263 mm², resulting in a transistor density of 118.3 million per square millimeter. The AMD chip has 26,800 million transistors spread across a much larger 520 mm² die, giving a density of just 51.5 million per square millimeter. The NVIDIA part achieves more than double the transistor density, which is a direct consequence of the smaller process node.

The core configurations differ substantially. The RTX 5070 Ti Mobile has 5,888 shading units, 184 texture mapping units, and 80 raster operation units. It also features 46 ray tracing cores and 184 tensor cores. The RX 6800 has 3,840 shading units, 240 TMUs, and 96 ROPs, along with 60 ray tracing cores. The NVIDIA part has more shading units but fewer TMUs and ROPs. The AMD card has more ray tracing cores by count, though the architectural implementation differs between Blackwell 2.0 and RDNA 2.0.

Memory architectures also diverge. The NVIDIA part uses 12 GB of GDDR7 memory on a 192-bit bus, delivering 672.0 GB/s of bandwidth. The AMD card uses 16 GB of GDDR6 on a 256-bit bus, providing 512.0 GB/s. The NVIDIA part has higher bandwidth despite a narrower bus, thanks to the newer GDDR7 standard. The AMD card compensates with more total capacity.

Specification Differences

The two cards differ across nearly every specification category. The NVIDIA GeForce RTX 5070 Ti Mobile has a base clock of 847 MHz and a boost clock of 1,447 MHz. The AMD Radeon RX 6800 runs much higher clocks: 1,700 MHz base, 2,105 MHz boost, and a game clock of 1,815 MHz. The AMD card relies on higher clocks to drive performance, while the NVIDIA part uses a wider architecture with more shading units.

Memory speed differs as well. The NVIDIA card runs at 1,750 MHz with 28 Gbps effective speed, while the AMD card runs at 2,000 MHz with 16 Gbps effective. The NVIDIA part's GDDR7 memory is faster per pin, but the AMD card's wider 256-bit bus helps close the bandwidth gap.

The power profiles are starkly different. The RTX 5070 Ti Mobile has a TDP of 60 W, while the RX 6800 has a TDP of 250 W. This is a 190 W difference. The NVIDIA part is an integrated graphics product (IGP) with no power connectors, while the AMD card is a dual-slot design requiring 2x 8-pin power connectors and a suggested 600 W power supply. The AMD card is also physically large: 267 mm in length, 120 mm in height, and 40 mm in width. The NVIDIA part's dimensions are listed as portable-device dependent.

The bus interfaces differ: PCIe 5.0 x16 for NVIDIA versus PCIe 4.0 x16 for AMD. Display outputs also differ, with the AMD card offering 1x HDMI 2.1, 2x DisplayPort 1.4a, and 1x USB Type-C, while the NVIDIA part's outputs are listed as portable-device dependent.

The release dates are far apart. The RTX 5070 Ti Mobile launched on 2025-02-28, while the RX 6800 launched on 2020-10-27. The AMD card has a launch MSRP of 579 USD, and it is now end-of-life. The NVIDIA part is active and its predecessor is the GeForce 40 Mobile series.

Where Each One Wins

The NVIDIA GeForce RTX 5070 Ti Mobile wins in modern graphics workloads. It leads in DirectX 12, DirectX 11, DirectX 10, Vulkan, and OpenCL. Its 20.9% Vulkan advantage and 14.6% DirectX 12 advantage suggest it is better suited for current and upcoming games and applications that use these APIs. The 487% OpenCL win is the standout result, indicating a massive advantage in OpenCL compute workloads, though the Passmark GPU Compute result complicates that picture slightly.

The AMD Radeon RX 6800 wins in two specific areas. Its 7% GPU Compute advantage suggests it handles certain compute tasks better, possibly those that favor its specific architecture or driver optimization. The G2D win, while small, shows it is not lacking in basic desktop performance. The RX 6800 also offers 16 GB of memory, which is 4 GB more than the NVIDIA part, potentially useful for very large datasets or high-resolution textures.

For a user building a desktop system with a traditional power supply and expecting to run compute-heavy tasks, the RX 6800 has a case. For a user prioritizing gaming performance in modern APIs, or needing a low-power integrated solution, the RTX 5070 Ti Mobile is the data-backed choice. The NVIDIA part wins more tests, has a higher average score, ranks higher in the percentile, and uses far less power. The AMD card's wins are narrower and confined to fewer scenarios, but they are real and worth considering for specific use cases.
