AMD Radeon RX 6700 vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

The NVIDIA GeForce RTX 5070 Ti Mobile and the AMD Radeon RX 6700 represent two very different generations of mobile graphics. The data shows a clear and consistent performance leader in the newer NVIDIA part, but the AMD card retains specific strengths in raw throughput metrics. This analysis compares their benchmark scores, architectural choices, and practical implications based strictly on recorded measurements.

Head-to-Head Benchmarks

The benchmark results leave no ambiguity about overall performance. The NVIDIA GeForce RTX 5070 Ti Mobile wins all nine head-to-head comparisons against the AMD Radeon RX 6700. The largest margin appears in the Geekbench Vulkan test, where the NVIDIA card scores 139,213 against 83,974 for the AMD card, a lead of 65.8%. This substantial gap indicates that the NVIDIA architecture handles Vulkan workloads significantly better, which matters for modern games and compute applications that use this API.

In Geekbench OpenCL, the NVIDIA card records 143,870 points versus 97,841 for the AMD card, a 47% advantage. OpenCL is a common cross-platform compute standard, and this result reinforces that the RTX 5070 Ti Mobile is not just a gaming part but also a capable compute device. The absolute numbers are high for both, but the relative difference is decisive.

The PassMark suite tells a similar story. In the DirectX 12 test, the NVIDIA card scores 102 against 71 for the AMD card, a 43.7% improvement. DirectX 12 is the foundation of most current PC games, so this result directly translates to expected frame rate advantages. The DirectX 11 test shows 237 versus 166, a 42.8% lead for NVIDIA. DirectX 11 remains relevant for many older titles and some current e-sports games, so this margin is practically significant.

The DirectX 10 test shows a 31.3% lead (151 vs 115), while the DirectX 9 test is the closest contest. Here, the NVIDIA card scores 259 and the AMD card scores 250, a narrow 3.6% difference. This suggests that for very old DirectX 9 titles, the two cards perform nearly identically, which is a minor win for the AMD card in terms of legacy compatibility.

In the PassMark G3D test, which is a general 3D graphics performance metric, the NVIDIA card scores 24,004 versus 18,931 for the AMD card, a 26.8% lead. This is the most commonly cited PassMark figure for comparing GPUs, and the difference is substantial. The PassMark GPU Compute test shows 10,101 versus 8,240, a 22.6% lead for NVIDIA. Compute workloads include physics simulations, video encoding, and some AI tasks, so this margin matters for content creators.

The PassMark G2D test, which measures 2D graphics performance, is close: 981 versus 936, a 4.8% lead for NVIDIA. This test has little impact on gaming but can matter for desktop usability and video playback. The overall pattern is consistent: the NVIDIA card leads by double digits in most modern and compute-heavy tests, with only legacy DirectX 9 and 2D tests showing near parity.

Where Each One Wins

The NVIDIA GeForce RTX 5070 Ti Mobile wins in every recorded benchmark category, so the decision framework centers on the magnitude of each win. The strongest case for NVIDIA is in Vulkan and OpenCL compute. A 65.8% lead in Vulkan and a 47% lead in OpenCL means that developers targeting these APIs will see dramatic performance differences. For users running Linux-based gaming, Vulkan is the primary API, and the data suggests the NVIDIA card is the superior choice there.

DirectX 12 and DirectX 11 wins of 43.7% and 42.8% respectively cover the vast majority of modern game titles. Any game built on these APIs will show a clear performance advantage on the NVIDIA card. The DirectX 10 win of 31.3% is also notable, as some older games still use this API. The PassMark G3D score, often used as a proxy for overall gaming performance, shows a 26.8% lead, which is a strong indicator for general 3D workloads.

The AMD Radeon RX 6700 does not win any benchmark, but it is not without merit. The closest margins are in DirectX 9 (3.6% difference) and G2D (4.8% difference). This means that for very old games or for basic 2D desktop work, the AMD card is nearly equivalent. The AMD card also has a higher base clock speed (1941 MHz vs 847 MHz) and a higher boost clock (2450 MHz vs 1447 MHz), but these higher clocks do not translate into higher benchmark scores. The architectural efficiency of the NVIDIA card overrides the raw clock advantage.

For compute workloads, the AMD card does have a higher FP16 throughput rating: 22.58 TFLOPS versus 17.04 TFLOPS for NVIDIA. However, the FP32 performance is higher on NVIDIA (17.04 TFLOPS vs 11.29 TFLOPS), and FP32 is more commonly used in general-purpose computing. The PassMark GPU Compute score of 22.6% in favor of NVIDIA confirms that the NVIDIA card is faster in real-world compute tests despite the AMD card's FP16 specification advantage.

Architecture Differences

The two cards come from fundamentally different design philosophies. The NVIDIA GeForce RTX 5070 Ti Mobile uses the GB205 chip built on the Blackwell 2.0 architecture, manufactured on a 5 nm process at TSMC. The AMD Radeon RX 6700 uses the Navi 22 chip on the RDNA 2.0 architecture, manufactured on a 7 nm process at the same foundry. The process node difference is significant: 5 nm allows for much higher transistor density, and the data confirms this. The NVIDIA chip packs 31,100 million transistors into a 263 mm² die, yielding a density of 118.3 million transistors per square millimeter. The AMD chip has 17,200 million transistors on a larger 335 mm² die, for a density of 51.3 million per square millimeter. This means the NVIDIA chip has nearly 1.8 times the transistor count on a smaller die, a direct result of the more advanced manufacturing process.

The memory subsystems are also different. The NVIDIA card uses 12 GB of GDDR7 memory on a 192-bit bus, delivering 672.0 GB/s of bandwidth. The AMD card uses 10 GB of GDDR6 memory on a 160-bit bus, providing 320.0 GB/s. The NVIDIA card has more than double the memory bandwidth, which is critical for high-resolution textures and compute tasks that access large datasets. The memory type difference, GDDR7 versus GDDR6, also affects efficiency and theoretical peak speeds.

The compute unit configurations favor NVIDIA in raw counts. The RTX 5070 Ti Mobile has 5,888 shading units, 184 texture mapping units, and 80 raster output units. The RX 6700 has 2,304 shading units, 144 TMUs, and 64 ROPs. The NVIDIA card also has 46 ray tracing cores and 184 tensor cores, while the AMD card has 36 ray accelerators (listed as 36 RT cores) and no tensor cores. The tensor cores are a key differentiator: they enable AI-accelerated features like DLSS, which the AMD card cannot use. The pixel rate is higher on the AMD card (156.8 GPixel/s vs 115.8 GPixel/s), and the texture rate is also higher (352.8 GTexel/s vs 266.2 GTexel/s), but these theoretical rates do not overcome the benchmark deficits.

Power consumption is a major architectural difference. The NVIDIA card has a TDP of 60 W and no power connectors, meaning it draws power directly from the motherboard slot. The AMD card has a TDP of 175 W and requires a single 8-pin power connector, along with a suggested 450 W power supply. This makes the NVIDIA card far more suitable for thin and light laptops, while the AMD card would need a larger chassis and better cooling solution. The NVIDIA card is listed as "IGP" slot width, meaning it is integrated into the motherboard package, while the AMD card is a dual-slot discrete card.

The Verdict

The data makes the choice clear for most users. The NVIDIA GeForce RTX 5070 Ti Mobile is the faster card in every benchmark test, with double-digit leads in the most important modern workloads. Its 65.8% advantage in Vulkan and 47% in OpenCL make it the superior choice for compute and cross-platform development. The 43.7% lead in DirectX 12 and 42.8% in DirectX 11 mean that gamers will see substantial frame rate improvements in current titles.

The NVIDIA card also offers practical advantages beyond raw scores. Its 60 W TDP and lack of power connectors make it suitable for thin laptops, while the AMD card's 175 W TDP and 8-pin connector require a larger, more power-hungry system. The 12 GB of GDDR7 memory with 672.0 GB/s bandwidth is more future-proof than 10 GB of GDDR6 at 320.0 GB/s. The presence of tensor cores on the NVIDIA card enables AI features that the AMD card lacks entirely.

The AMD Radeon RX 6700 is not a poor performer. Its 75th percentile ranking versus the NVIDIA card's 80th percentile means it still outperforms the majority of GPUs in the database. Its higher pixel rate and texture rate suggest it can handle certain rasterization-heavy workloads well, and its DirectX 9 performance is almost identical to the NVIDIA card. The FP16 throughput of 22.58 TFLOPS is higher than NVIDIA's 17.04 TFLOPS, which could benefit specific compute tasks that use half-precision math. However, these advantages are narrow and do not appear in any recorded benchmark.

Users who prioritize maximum performance in modern games and compute applications should choose the NVIDIA card. It wins every test, often by large margins, and offers more memory and bandwidth. Users with legacy DirectX 9 software or who need a card that can slot into a larger desktop chassis might consider the AMD card, but the data does not support that choice for general use. The average benchmark score of 35,435 for NVIDIA versus 30,433 for AMD, a 16.4% difference, summarizes the overall superiority of the newer card.
