AMD Radeon RX 6650M vs NVIDIA GeForce RTX 5070 Ti Comparison

Head-to-Head Benchmarks

The benchmark data delivers a decisive result: the NVIDIA GeForce RTX 5070 Ti wins both recorded head-to-head tests, and it does so by a commanding margin. The AMD Radeon RX 6650M trails by 69% in Geekbench OpenCL and by 65.5% in Geekbench Vulkan. These deltas are not marginal; they represent a generational chasm between a mobile-focused GPU from the Radeon RX 6000 series and a current-generation desktop-class adapter.

In the Geekbench OpenCL test, the RTX 5070 Ti scores 212,363 points against the RX 6650M's 65,800. The 69% gap means the NVIDIA part delivers roughly three times the compute throughput in this workload. The Vulkan test tells a similar story: 225,122 versus 77,735, a 65.5% deficit for the AMD part. Vulkan is often considered a more efficient API for GPU-bound tasks, but the RTX 5070 Ti still runs away with it. The data shows no test where the RX 6650M closes the gap or overtakes its rival.

Looking at overall database averages, the picture is more nuanced but still favors NVIDIA. The RTX 5070 Ti has an average benchmark score of 49,957, while the RX 6650M sits at 71,768. That might look inverted at first glance, but the averages are computed across different test sets: the AMD part only has Geekbench OpenCL and Vulkan results recorded, while the NVIDIA part includes a broader suite such as 3DMark Steel Nomad DX12 and multiple Passmark tests. The head-to-head comparisons use only the overlapping tests, and there the NVIDIA advantage is unambiguous.

The RTX 5070 Ti's percentile ranking versus all GPUs is 86, while the RX 6650M ranks at 91. This is a curious split: the older AMD mobile chip holds a higher percentile despite losing every common benchmark. That reflects the different reference pools and the fact that the RX 6650M's recorded scores are competitive within its own mobile class, whereas the RTX 5070 Ti's large test suite includes some lower-scoring legacy DirectX tests that drag its average percentile down. For direct comparisons, the head-to-head deltas are the authoritative measure.

Where Each One Wins

The RTX 5070 Ti wins every recorded benchmark category. Its strengths are most pronounced in compute-heavy synthetic workloads, where its 43.94 TFLOPS FP32 throughput and 280 tensor cores provide massive parallel processing capability. The Geekbench Vulkan score of 225,122 is particularly telling: Vulkan is a low-overhead API that scales well with raw shader count and memory bandwidth, both areas where the NVIDIA part is overwhelmingly superior.

The RX 6650M does not win any recorded test. However, its niche is defined by its physical and power profile. The data shows a 120 W TDP against 300 W for the RTX 5070 Ti, and the AMD chip is built for integrated or portable-device deployment, with a slot width of "IGP" and no power connectors. The NVIDIA part requires a dual-slot cooler, a 1x 16-pin power connector, and a 700 W suggested PSU. For workloads where power draw and physical footprint are the primary constraints, the RX 6650M is the only viable option in this pairing, despite its lower scores.

Where the RTX 5070 Ti clearly wins is in memory capacity and bandwidth. It carries 16 GB of GDDR7 on a 256-bit bus, yielding 896.0 GB/s of bandwidth. The RX 6650M has 8 GB of GDDR6 on a 128-bit bus, capped at 224.0 GB/s. For large datasets, texture streaming, or high-resolution rendering, that fourfold bandwidth advantage is decisive. The RX 6650M also has no tensor cores, while the RTX 5070 Ti includes 280 of them, making the NVIDIA part the only one in this pairing with any AI-accelerated compute capability.

Architecture Differences

The two GPUs come from different architectural generations with starkly different design goals. The AMD Radeon RX 6650M uses the Navi 23 chip built on RDNA 2.0, fabricated on a 7 nm TSMC process. It integrates 11,060 million transistors on a 237 mm² die, giving a transistor density of 46.7 million per mm². The NVIDIA GeForce RTX 5070 Ti uses the GB203 chip on Blackwell 2.0, fabricated on a 5 nm TSMC process. It packs 45,600 million transistors on a 378 mm² die, achieving a transistor density of 120.6 million per mm². The NVIDIA chip has more than four times the transistor count and more than 2.5 times the density.

The shader configuration is equally lopsided. The RX 6650M has 1,792 shading units, 112 texture mapping units, 64 ROPs, and 28 ray tracing cores. The RTX 5070 Ti has 8,960 shading units, 280 TMUs, 96 ROPs, 70 RT cores, and 280 tensor cores. That is a 5x advantage in shading units, a 2.5x advantage in TMUs, and a 50% advantage in ROPs. The AMD part's FP32 throughput is 8.659 TFLOPS, while the NVIDIA part delivers 43.94 TFLOPS, a 5.1x difference. The FP16 numbers are also revealing: the RX 6650M offers 17.32 TFLOPS with a 2:1 ratio, while the RTX 5070 Ti provides 43.94 TFLOPS at a 1:1 ratio, meaning the NVIDIA part does not rely on packed math to reach its peak.

Memory architecture differs fundamentally. The RX 6650M uses GDDR6 at 1750 MHz with 14 Gbps effective speed, producing 224.0 GB/s across a 128-bit bus. The RTX 5070 Ti uses GDDR7 also at 1750 MHz but with 28 Gbps effective speed, producing 896.0 GB/s across a 256-bit bus. The bus width doubles and the effective speed doubles, quadrupling bandwidth. The RTX 5070 Ti also uses PCIe 5.0 x16, while the RX 6650M is limited to PCIe 4.0 x8.

The process nodes and release timing reflect a generational leap. The RX 6650M was released on 2022-01-03 and is end-of-life, with its predecessor listed as Polaris Mobile. The RTX 5070 Ti was released on 2025-02-19, is active in production, and lists its predecessor as GeForce 40 and its successor as GeForce 60. The NVIDIA part is also a dual-slot card with dimensions of 304 mm length, 137 mm height, and 48 mm width, while the AMD part is an IGP-class chip with dimensions listed as portable-device dependent.

The Verdict

The data is unambiguous: the NVIDIA GeForce RTX 5070 Ti is the superior GPU in every measured benchmark. It leads by 69% in OpenCL and 65.5% in Vulkan, and it offers more than five times the FP32 throughput, four times the memory bandwidth, and double the memory capacity. For any workload that appears in the database, the RTX 5070 Ti is the correct choice.

The RX 6650M's sole advantage is in deployment flexibility. Its 120 W TDP, IGP slot width, and lack of external power connectors make it suitable for portable or integrated systems where a 300 W dual-slot card with a 16-pin connector and 700 W PSU requirement simply cannot fit. The recorded data shows no performance scenario where the AMD part wins, so the decision rests entirely on physical and power constraints.

Users who already have a system capable of housing the RTX 5070 Ti should choose it without hesitation. Its 16 GB GDDR7 memory and 896.0 GB/s bandwidth are future-proof for high-resolution textures, and its 280 tensor cores provide AI acceleration that the RX 6650M lacks entirely. The RTX 5070 Ti's percentile ranking of 86 versus the RX 6650M's 91 is a statistical artifact of different test sets, not a performance indicator; the head-to-head deltas are the only fair comparison, and they favor NVIDIA completely.
