AMD Radeon RX 6700M vs NVIDIA GeForce RTX 2080 Ti Comparison

The Verdict

The data is unambiguous: the NVIDIA GeForce RTX 2080 Ti wins every single head-to-head benchmark in the database, taking all 10 recorded tests against the AMD Radeon RX 6700M. The RTX 2080 Ti posts a 75th percentile ranking among all GPUs, while the RX 6700M sits at the 71st percentile. The average benchmark score tells the same story: 29,783 for the NVIDIA part versus 25,633 for the AMD mobile chip, a gap of roughly 16%. The largest single victory comes in Passmark GPU Compute, where the RTX 2080 Ti leads by 93.7%, and the smallest margin is in Passmark DirectX 12, still a decisive 29.2% edge. For anyone prioritizing raw performance, the RTX 2080 Ti is the clear pick. The RX 6700M is not without merit, however: it carries a far lower 135 W TDP versus 250 W, and it is built on a more modern 7 nm process with a much smaller die. The data shows the RX 6700M is the right choice for compact or thermally constrained systems where efficiency matters more than top-end frame rates. The RTX 2080 Ti is a desktop-class powerhouse; the RX 6700M is a mobile-focused part that sacrifices performance for portability.

Architecture Differences

The two GPUs come from fundamentally different design philosophies and process generations. The RTX 2080 Ti is built on NVIDIA's Turing architecture, fabricated on a 12 nm process at TSMC. Its chip, TU102, packs 18,600 million transistors onto a 754 mm² die, yielding a transistor density of 24.7 million per square millimeter. The RX 6700M uses AMD's RDNA 2.0 architecture, manufactured on a more advanced 7 nm node, also by TSMC. Its Navi 22 chip contains 17,200 million transistors but on a much smaller 335 mm² die, giving a density of 51.3 million per square millimeter, more than double that of the NVIDIA chip.

The RTX 2080 Ti is equipped with 68 ray tracing cores and 544 tensor cores, reflecting Turing's emphasis on both hardware ray tracing and AI acceleration. The RX 6700M has 36 ray accelerators but no tensor cores at all, which means it lacks dedicated AI hardware that the NVIDIA card can leverage in supported workloads. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical in the recorded data.

The RTX 2080 Ti is also a much larger card physically, at 267 mm in length, 116 mm in height, and 35 mm in width, and it requires dual-slot spacing with two 8-pin power connectors. The RX 6700M is an integrated graphics processor (IGP) for mobile designs, with no dimensions or power connectors listed, and it runs over PCIe 4.0 x16, while the RTX 2080 Ti uses the older PCIe 3.0 x16 interface. The RTX 2080 Ti has a 1x HDMI, 3x DisplayPort, and 1x USB-C output, while the RX 6700M is marked as portable device dependent for display outputs.

Specification Differences

The specification sheet shows several key divergences. On process, the RTX 2080 Ti uses 12 nm, the RX 6700M uses 7 nm. Transistor count is close, 18,600 million versus 17,200 million, but die size is radically different at 754 mm² versus 335 mm². The RTX 2080 Ti has a base clock of 1350 MHz and a boost of 1545 MHz; the RX 6700M starts at 1489 MHz, boosts to 2400 MHz, and has a game clock of 2300 MHz. Memory configurations also diverge: the RTX 2080 Ti has 11 GB of GDDR6 on a 352-bit bus with 616 GB/s bandwidth, while the RX 6700M has 10 GB on a 160-bit bus with 320 GB/s bandwidth.

The compute resources are heavily in NVIDIA's favor. The RTX 2080 Ti has 4352 shading units, 272 texture mapping units, and 88 render output units, versus 2304 shaders, 144 TMUs, and 64 ROPs on the RX 6700M. The RTX 2080 Ti also has 68 ray tracing cores and 544 tensor cores, while the RX 6700M has 36 ray cores and no tensor cores. Pixel rate is 136.0 GPixel/s for NVIDIA versus 153.6 GPixel/s for AMD, a rare win for the mobile part. Texture rate is 420.2 GTexel/s versus 345.6 GTexel/s, and FP32 performance is 13.45 TFLOPS versus 11.06 TFLOPS. FP16 performance follows the same pattern: 26.90 TFLOPS versus 22.12 TFLOPS.

Power and physical specs separate them further. The RTX 2080 Ti draws 250 W and needs a 600 W PSU; the RX 6700M draws 135 W and lists no PSU requirement. The RTX 2080 Ti is dual-slot with 2x 8-pin connectors; the RX 6700M is an IGP with no connectors. The RTX 2080 Ti was released on 2018-09-19, while the RX 6700M came later on 2021-05-30. Both are end-of-life parts.

Head-to-Head Benchmarks

The 3DMark Steel Nomad DX12 test opens the results with a commanding win for the RTX 2080 Ti. It scores 3537 against 1845 for the RX 6700M, a 91.7% lead. This is the second-largest margin of the entire suite and shows a massive advantage in modern DX12 gaming workloads.

Geekbench OpenCL sees the RTX 2080 Ti at 128,171 versus 77,666, a 65% win. Geekbench Vulkan follows with 132,930 versus 90,816, a 46.4% margin. These compute-oriented tests confirm that NVIDIA's larger core count and higher FP32 throughput translate directly into superior raw compute.

The older DirectX APIs also favor NVIDIA. Passmark DirectX 10 shows 153 versus 92, a 66.3% lead. DirectX 11 shows 190 versus 129, a 47.3% win. DirectX 9 shows 235 versus 155, a 51.6% lead. The smallest gap in the entire suite is DirectX 12 at 84 versus 65, a 29.2% advantage. This suggests the RX 6600M closes the gap somewhat in modern API workloads, though it still loses.

Passmark G2D, a 2D rendering test, gives the RTX 2080 Ti a 927 to 555 win, a 67% margin. Passmark G3D, the main 3D gaming score, shows the RTX 2080 Ti at 21,548 versus 13,536, a 59.2% lead. Finally, Passmark GPU Compute delivers the largest margin of all: 10,056 versus 5,191, a 93.7% victory for the NVIDIA card.

The RX 6700M, while slower in every test, does show competitive efficiency. Its 135 W TDP is less than half the RTX 2080 Ti's 250 W, and its 7 nm process produces a far denser chip. But in the database's recorded benchmarks, the RTX 2080 Ti is simply faster across the board, and the 10-win sweep leaves no ambiguity about which part delivers more frame rate and compute performance.

The RTX 2080 Ti's nearest rivals in the database are the NVIDIA GeForce RTX 5070 Mobile (0.5% faster), the RTX 3070 Ti (0.5% faster), the AMD Radeon RX 6800 (1% faster), and the AMD FirePro W8000 (2% slower). The RX 6700M's closest competitors are the AMD Radeon Pro W5700 (0.4% faster), the NVIDIA GeForce RTX 2080 Ti Mobile (0.4% faster), and the AMD FirePro D700 (0.8% faster). This places the RX 6700M roughly on par with last generation's top mobile parts, while the RTX 2080 Ti sits in a higher tier altogether.
