AMD Radeon RX 6650 XT vs NVIDIA GeForce RTX 5090 D V2 Comparison

Head-to-Head Benchmarks

The recorded data contains one direct head-to-head comparison between the AMD Radeon RX 6650 XT and the NVIDIA GeForce RTX 5090 D V2, and it is a decisive sweep. In the 3DMark Steel Nomad DX12 test, the NVIDIA card scores 16,504 points against 1,859 points for the AMD card. That is a delta of 88.7% in favor of the RTX 5090 D V2, meaning the NVIDIA part delivers roughly nine times the performance in this particular workload. The result is unambiguous: the RTX 5090 D V2 is in a completely different performance class.

The wider benchmark database reinforces the gap, though it also reveals an oddity. The AMD Radeon RX 6650 XT has an average benchmark score of 19,765 across multiple tests, while the NVIDIA GeForce RTX 5090 D V2 has only a single recorded benchmark, the same Steel Nomad run, giving it an average of 16,504. On average scores alone, the AMD card appears ahead, but that is a function of test selection rather than raw capability. The AMD card has eleven recorded tests spanning DirectX 9 through DirectX 12, OpenCL, Vulkan, Metal, and compute workloads. The NVIDIA card has exactly one. When comparing only the shared test, the RTX 5090 D V2 is faster by the aforementioned 88.7%.

Looking at individual AMD results provides context for what the RX 6650 XT can do in isolation. Its strongest recorded results include a Geekbench Metal score of 97,969, a Geekbench Vulkan score of 81,306, and a Passmark G3D score of 17,166. Its Passmark DirectX 12 score is only 62, while its DirectX 11 score sits at 169 and DirectX 10 at 109. The Passmark G2D result is 918, and the GPU compute score is 7,532. These numbers indicate a capable midrange part, but nothing in that list approaches the raw throughput of the RTX 5090 D V2's single Steel Nomad result.

The nearest rival data for each card further illustrates their respective market positions. The RX 6650 XT sits in a dense pack of workstation and professional cards: it trails the NVIDIA Tesla K40m by 0.6%, leads the AMD FirePro D300 by 0.7%, trails the AMD FirePro W7000 by 0.7%, and leads the NVIDIA Quadro K5200 by 0.8%. This is a tightly contested performance band where the RX 6650 XT holds its own against older professional hardware. The RTX 5090 D V2, by contrast, is statistically tied with the NVIDIA T400 (0.0% delta), leads the AMD Radeon PRO W7500 by 0.5%, leads the NVIDIA RTX PRO 6000 Blackwell by 0.6%, and leads the AMD Radeon RX 5700 XT by 0.9%. Those deltas are all within one percent, which is remarkable given the hardware involved, but the database only has that one 3DMark result for the RTX 5090 D V2, so its nearest rival list is built on a very narrow sample.

The percentile rankings tell a similar story. The RX 6650 XT sits in the 65th percentile of all GPUs in the database, which is respectable for a card from the Radeon RX 6000 series. The RTX 5090 D V2 sits in the 59th percentile, which looks lower, but again, that ranking is derived from a single benchmark. The percentile field does not account for the disparity in test coverage, so it should be read with caution. The unambiguous takeaway from the head-to-head data is that the RTX 5090 D V2 dominates the RX 6650 XT in the only test where both have recorded scores.

The Verdict

The data points to a clear verdict: choose the NVIDIA GeForce RTX 5090 D V2 if you need maximum raw performance in modern DirectX 12 workloads. Its 3DMark Steel Nomad score of 16,504 versus 1,859 for the AMD card is a 88.7% advantage, and that is the only direct comparison available. No amount of additional AMD benchmark results changes the outcome of that single test. The RTX 5090 D V2 is the faster card, period.

However, the verdict is not purely about speed. The RX 6650 XT has far broader benchmark coverage in the database, with eleven recorded tests across multiple APIs and workload types. Its average benchmark score of 19,765 exceeds the RTX 5090 D V2's 16,504, but that is misleading because the averages are computed over different test sets. If the goal is a card with proven results across DirectX 9, DirectX 10, DirectX 11, DirectX 12, OpenCL, Vulkan, and Metal, the RX 6650 XT has the recorded evidence. The RTX 5090 D V2 has only one data point.

The production status also matters. The RX 6650 XT is end-of-life, while the RTX 5090 D V2 is active. The AMD card launched on 2022-05-09 and belongs to the Navi II (RX 6000) generation, whereas the NVIDIA card launched on 2025-08-14 as part of the GeForce 50 series. For anyone looking at current hardware, the RTX 5090 D V2 is the one still in production. The RX 6650 XT is a legacy product.

The launch MSRP for the RX 6650 XT is 399 USD. The launch MSRP for the RTX 5090 D V2 is 2,299 USD. That is a substantial difference, but the performance gap in the recorded benchmark is even more substantial. The RTX 5090 D V2 delivers a near-ninefold improvement in the Steel Nomad test, so on a performance-per-dollar basis, the delta is not as lopsided as the raw scores suggest. Still, the AMD card is the only one of the two that can be described as a midrange option.

Where Each One Wins

The AMD Radeon RX 6650 XT wins in benchmark coverage and versatility. It has recorded scores in eleven different tests, spanning legacy DirectX APIs, modern DirectX 12, compute workloads, and cross-vendor APIs like Vulkan and OpenCL. Its Passmark DirectX 9 score of 215, DirectX 10 score of 109, and DirectX 11 score of 169 indicate it handles older workloads without issue. Its Geekbench OpenCL score of 10,111 and Passmark GPU compute score of 7,532 show it can do general-purpose compute tasks. For a card that is end-of-life, it has a well-documented performance profile. It also ranks in the 65th percentile of all GPUs, which is higher than the RTX 5090 D V2's 59th percentile, though again, that ranking is based on different amounts of data.

The NVIDIA GeForce RTX 5090 D V2 wins in raw performance, memory capacity, and modern platform support. Its 24 GB of GDDR7 memory dwarfs the 8 GB of GDDR6 in the AMD card. Its memory bandwidth of 1.34 TB/s is nearly five times the 280.3 GB/s of the RX 6650 XT. Its FP32 throughput of 104.8 TFLOPS is roughly ten times the 10.79 TFLOPS of the AMD card. Its texture rate of 1,636.8 GTexel/s and pixel rate of 423.6 GPixel/s both exceed the AMD card by similar margins. It also supports PCIe 5.0 x16, whereas the RX 6650 XT uses PCIe 4.0 x8, which matters for systems with newer motherboards.

The RTX 5090 D V2 also wins on architectural modernity. It uses the Blackwell 2.0 architecture on a 5 nm process, while the RX 6650 XT uses RDNA 2.0 on a 7 nm process. The NVIDIA card has 170 RT cores and 680 tensor cores, while the AMD card has 32 RT cores and no tensor cores. The NVIDIA card is active and recently released, while the AMD card is end-of-life. For anyone building a new high-end system, the RTX 5090 D V2 is the forward-looking choice.
