AMD Radeon RX 6800M vs NVIDIA GeForce RTX 4070 Ti SUPER Comparison

The NVIDIA GeForce RTX 4070 Ti SUPER is the decisive winner in this comparison, taking 9 out of 10 head-to-head benchmarks and posting an average score of 31,087 points compared to the AMD Radeon RX 6800M's 28,874 points. The data shows a massive performance gulf in raw compute and rasterization, though the AMD mobile part claims a notable victory in Vulkan graphics, demonstrating that API-level optimization can dramatically shift results. The RTX 4070 Ti SUPER sits in the 76th percentile of all GPUs, while the RX 6800M lands at the 74th percentile, a narrow overall ranking gap that masks the scale of their benchmark disparities.

Head-to-Head Benchmarks

The single largest margin comes in Passmark GPU Compute, where the RTX 4070 Ti SUPER scores 18,372 against the RX 6800M's 5,032 — a 265.1% advantage. This result reflects the NVIDIA part's 44.10 TFLOPS of FP32 throughput versus the AMD part's 12.24 TFLOPS, indicating a fundamental difference in raw mathematical horsepower that extends beyond gaming into productivity and compute workloads.

In 3DMark Steel Nomad DX12, the RTX 4070 Ti SUPER scores 5,569 versus 2,238 for the RX 6800M, a 148.8% lead. This is the closest test to modern gaming conditions in the dataset, and the gap is enormous. The Passmark G3D result tells a similar story: 31,811 versus 13,261, a 139.9% margin. DirectX 11 sees a 118.9% advantage (278 vs 127), while DirectX 12 shows an 83.1% edge (119 vs 65). These consistent wins across multiple DX versions indicate the NVIDIA architecture scales better across API generations, not just in one optimized path.

Legacy API tests reinforce the pattern. Passmark DirectX 9 yields 360 for NVIDIA versus 147 for AMD, a 144.9% difference, and DirectX 10 shows 181 versus 101, a 79.2% edge. The 2D performance gap is similarly lopsided at 127.7% (1,225 vs 538), suggesting the RTX 4070 Ti SUPER handles even non-gaming framebuffer operations far more efficiently.

The Geekbench OpenCL result adds another data point: 199,267 versus 87,621, a 127.4% lead. This cross-manufacturer compute benchmark confirms that the NVIDIA's advantage is not confined to a single test suite.

The AMD Radeon RX 6800M's sole victory is striking. In Geekbench Vulkan, it scores 94,766 versus the RTX 4070 Ti SUPER's 53,683 — a 43.4% margin in AMD's favor. This is the only benchmark where the roles reverse, and the magnitude is substantial. The result suggests that Vulkan's low-level access allows the RDNA 2.0 architecture to leverage its design in ways that DX12 and OpenCL tests do not capture, though it does not translate into wins in any other test.

Architecture Differences

The two GPUs represent different design philosophies and process generations. NVIDIA's AD103 chip uses the Ada Lovelace architecture on a 5 nm TSMC process, packing 45,900 million transistors into a 379 mm² die for a density of 121.1 million transistors per mm². AMD's Navi 22 uses RDNA 2.0 on a 7 nm TSMC process, with 17,200 million transistors on a 335 mm² die — a density of just 51.3 million per mm².

The NVIDIA chip carries 8,448 shading units, 264 texture mapping units, and 96 ROPs, against AMD's 2,560 shaders, 160 TMUs, and 64 ROPs. Ray tracing hardware reflects the same imbalance: 66 RT cores on NVIDIA versus 40 on AMD. NVIDIA also includes 264 tensor cores, a feature AMD lacks entirely, which explains the RTX's commanding lead in compute-oriented tests like Passmark GPU Compute.

Memory subsystems differ sharply. The RTX 4070 Ti SUPER uses 16 GB of GDDR6X on a 256-bit bus, delivering 672.3 GB/s of bandwidth. The RX 6800M has 12 GB of GDDR6 on a 192-bit bus, yielding 384.0 GB/s. The NVIDIA part's bandwidth advantage is 75%, which directly contributes to its higher pixel rate of 250.6 GPixel/s versus 153.0 GPixel/s, and texture rate of 689.0 GTexel/s versus 382.4 GTexel/s.

Clock speeds are closer than the specs suggest. NVIDIA runs at a 2,340 MHz base and 2,610 MHz boost; AMD runs at 2,116 MHz base and 2,390 MHz boost, with a 2,300 MHz game clock. But the NVIDIA's massive shader count means its FP32 output is 44.10 TFLOPS versus AMD's 12.24 TFLOPS. AMD's FP16 rate of 24.47 TFLOPS exceeds its FP32 rate via a 2:1 ratio, while NVIDIA matches FP16 to FP32 at 44.10 TFLOPS, but the absolute numbers still favor NVIDIA.

Where Each One Wins

The NVIDIA GeForce RTX 4070 Ti SUPER wins every category except one. It dominates in DirectX 10, 11, and 12 tests, all legacy DirectX versions, 2D performance, OpenCL compute, GPU compute, and the modern 3DMark Steel Nomad benchmark. Its 265.1% lead in GPU compute makes it the clear choice for any workload involving general-purpose GPU processing, machine learning inference via its tensor cores, or CUDA-accelerated applications. The 148.8% margin in 3DMark Steel Nomad positions it as the superior option for current-generation AAA gaming at high resolutions or detail settings.

The AMD Radeon RX 6800M wins exactly one test: Geekbench Vulkan, where its 43.4% margin is substantial and unambiguous. For developers or users running Vulkan-specific applications or games that rely heavily on that API, the RX 6800M offers a measurable advantage. This win does not extend to any other benchmark, so it remains a narrow, API-specific strength rather than an overall performance edge. Additionally, the RX 6800M's 145 W TDP and IGP form factor indicate it is designed for mobile integration, whereas the RTX 4070 Ti SUPER is a triple-slot desktop card requiring a 600 W PSU and a 16-pin connector.

The Verdict

Choose the NVIDIA GeForce RTX 4070 Ti SUPER for virtually any use case where absolute performance matters. The data is unambiguous: it wins 9 of 10 benchmarks, with leads ranging from 79.2% to 265.1%. Its 44.10 TFLOPS FP32 throughput, 66 RT cores, and 264 tensor cores make it the stronger pick for gaming, rendering, and compute. The 16 GB GDDR6X memory on a 256-bit bus provides 672.3 GB/s of bandwidth, more than enough for high-resolution textures and demanding workloads. Its launch MSRP was 799 USD, and it sits at the 76th percentile of all GPUs.

Choose the AMD Radeon RX 6800M only if your workload is dominated by Vulkan APIs and you require a mobile form factor. Its 43.4% Vulkan victory is real and significant, and its 145 W TDP with integrated design makes it suitable for laptops where the RTX 4070 Ti SUPER's 285 W TDP and triple-slot dimensions would be impossible. The RX 6800M's 12 GB memory and 384.0 GB/s bandwidth are adequate for its class, and its 74th percentile ranking shows it remains competitive in the broader GPU landscape. But for desktop users seeking maximum performance, the RTX 4070 Ti SUPER is the definitive choice, backed by a 31,087 average benchmark score versus 28,874 for the AMD part.
