Architecture Differences

The two GPUs come from fundamentally different design schools. The NVIDIA GeForce RTX 3070 Ti Mobile uses the GA104 chip built on Samsung's 8 nm process, packing 17,400 million transistors into a 392 mm² die for a transistor density of 44.4 million per square millimeter. The AMD Radeon RX 6650 XT uses the Navi 23 chip on TSMC's 7 nm process, with 11,060 million transistors on a 237 mm² die, yielding a slightly higher density of 46.7 million per square millimeter.

The NVIDIA architecture is Ampere, a generation that pairs 5888 shading units with 184 texture mapping units and 96 ROPs. It also includes 46 RT cores and 184 tensor cores, which means hardware-accelerated ray tracing and AI-accelerated features are both present. The AMD card is RDNA 2.0, with 2048 shading units, 128 TMUs, 64 ROPs, and 32 RT cores. It has no tensor cores, so any machine learning workloads that rely on those units are not applicable on the AMD side.

Clock behavior differs sharply. The AMD card runs a 2055 MHz base clock and a 2635 MHz boost clock, while the NVIDIA card is far more conservative at 915 MHz base and 1410 MHz boost. That clock gap helps explain why the AMD card reaches higher pixel and texture rates despite having fewer execution units. The AMD card outputs 168.6 GPixel/s and 337.3 GTexel/s, while the NVIDIA card produces 135.4 GPixel/s and 259.4 GTexel/s.

Shader throughput tells a different story. The NVIDIA card reaches 16.60 TFLOPS FP32, and its FP16 rate is identical at 16.60 TFLOPS (1:1 ratio). The AMD card delivers 10.79 TFLOPS FP32 but doubles its FP16 rate to 21.59 TFLOPS (2:1 ratio). That means the AMD card has the advantage in half-precision compute, while the NVIDIA card leads in single-precision.

Memory configurations also diverge. Both cards have 8 GB of GDDR6, but the NVIDIA card uses a 256-bit bus for 448.0 GB/s bandwidth, while the AMD card uses a 128-bit bus for 280.3 GB/s. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card is a mobile part with no power connectors listed (portable device dependent outputs), while the AMD card is a dual-slot desktop board with one 8-pin connector and a suggested PSU of 450 W. Power draw is listed at 115 W for the NVIDIA mobile GPU and 176 W for the AMD desktop card.

Head-to-Head Benchmarks

The most lopsided result in the data is Geekbench OpenCL, where the NVIDIA GeForce RTX 3070 Ti Mobile scores 106022 against 10111 for the AMD Radeon RX 6650 XT. That is a 948.6% delta, a figure so large it suggests the test is heavily influenced by the NVIDIA card's tensor core count and driver-level compute optimizations. No other benchmark comes close to that margin.

The next biggest gap is in 3DMark Steel Nomad DX12, where the NVIDIA card scores 2572 versus 1859, a 38.4% lead. This is a modern DirectX 12 workload, so it carries weight for current-generation gaming scenarios. The NVIDIA card also wins Geekbench Vulkan with 100027 against 81306, a 23% advantage.

Passmark results are more mixed. The NVIDIA card wins DirectX 10 (124 vs 109, 13.8%), DirectX 12 (73 vs 62, 17.7%), and G3D (17727 vs 17166, 3.3%). The AMD card wins DirectX 11 (169 vs 153, 9.5%), DirectX 9 (215 vs 196, 8.8%), G2D (918 vs 783, 14.7%), and GPU Compute (7532 vs 7504, 0.4%).

The pattern is revealing. The NVIDIA card tends to win in newer or more compute-heavy workloads, while the AMD card holds its ground in legacy DirectX paths and 2D performance. The G3D margin is slim at 3.3%, which suggests that in a broad rasterization average, the two GPUs are close, but the NVIDIA card's wins in DX12 and Vulkan are more relevant to modern titles. The AMD card's GPU Compute win is negligible at 0.4%, effectively a tie.

The Verdict

The data points to the NVIDIA GeForce RTX 3070 Ti Mobile as the stronger overall GPU. Its average benchmark score of 23518 versus 19765 for the AMD Radeon RX 6650 XT, combined with a 69th percentile ranking versus 65th, puts it clearly ahead in aggregate. It wins six of the ten head-to-head benchmarks, and its victories include the most demanding modern workloads: 3DMark Steel Nomad DX12 at 38.4% ahead, Geekbench Vulkan at 23% ahead, and Passmark DirectX 12 at 17.7% ahead.

The AMD card is not without merit. It wins in Passmark DirectX 11, DirectX 9, G2D, and GPU Compute, and its higher clock speeds allow it to post superior pixel and texture rates. For users who prioritize legacy API performance or 2D desktop responsiveness, the AMD card has a case. But those wins are in older or lighter workloads, and the margins are smaller than the NVIDIA card's modern-API victories.

The compute picture is more nuanced. Geekbench OpenCL heavily favors NVIDIA (948.6% delta), but Passmark GPU Compute slightly favors AMD (0.4% delta). The NVIDIA card's FP32 throughput is higher at 16.60 TFLOPS versus 10.79 TFLOPS, while the AMD card has the edge in FP16 at 21.59 TFLOPS versus 16.60 TFLOPS. The choice there depends on the precision requirements of the workload.

Given the modern gaming focus of both cards, the NVIDIA GeForce RTX 3070 Ti Mobile is the safer recommendation from the recorded data. Its DX12 and Vulkan wins align with current and near-future titles, and its memory bandwidth advantage (448.0 GB/s vs 280.3 GB/s) supports higher-resolution textures and more aggressive settings.

Where Each One Wins

The NVIDIA GeForce RTX 3070 Ti Mobile wins in 3DMark Steel Nomad DX12 (2572 vs 1859, 38.4% ahead), Geekbench OpenCL (106022 vs 10111, 948.6% ahead), Geekbench Vulkan (100027 vs 81306, 23% ahead), Passmark DirectX 10 (124 vs 109, 13.8% ahead), Passmark DirectX 12 (73 vs 62, 17.7% ahead), and Passmark G3D (17727 vs 17166, 3.3% ahead). These are mostly modern API and compute-heavy workloads, which makes the NVIDIA card the pick for current-generation gaming, Vulkan-based titles, and general GPU compute that leverages FP32 throughput or tensor cores.

The AMD Radeon RX 6650 XT wins in Passmark DirectX 11 (169 vs 153, 9.5% ahead), Passmark DirectX 9 (215 vs 196, 8.8% ahead), Passmark G2D (918 vs 783, 14.7% ahead), and Passmark GPU Compute (7532 vs 7504, 0.4% ahead). Its higher clock speeds give it superior pixel and texture rates, which may help in older DirectX 9 and DirectX 11 titles that respond well to raw fill rate. The G2D win suggests stronger 2D desktop performance, and the FP16 advantage (21.59 TFLOPS vs 16.60 TFLOPS) makes it the better choice for half-precision compute workloads.

For users deciding between the two, the pattern is clear. The NVIDIA card dominates modern APIs and most compute scenarios, while the AMD card holds specific advantages in legacy APIs, 2D performance, and FP16 throughput. The NVIDIA card's higher average score, higher percentile rank, and six benchmark wins make it the default choice for most use cases, with the AMD card appealing only to those with specific legacy or half-precision needs.
