AMD Radeon RX 6600 XT vs NVIDIA GeForce RTX 5060 Mobile Comparison

The Verdict

The data presents a clear split between two very different products. The NVIDIA GeForce RTX 5060 Mobile wins 9 of the 10 head-to-head benchmark comparisons, making it the definitive performance leader in this matchup. Its most dominant victory comes in the 3DMark Steel Nomad DX12 test, where it scores 3013.5 versus the AMD Radeon RX 6600 XT's 1804, a 40.1% advantage. The AMD card claims only one win, in the Passmark G2D test, where it scores 912 against 876, a 4.1% edge.

However, the verdict is not simply "NVIDIA wins." The RTX 5060 Mobile is a laptop part with a 45 W TDP, while the RX 6600 XT is a desktop card with a 160 W TDP. The database shows the NVIDIA part achieves its wins while consuming dramatically less power, which matters for system builders. The RX 6600 XT remains viable for desktop users who prioritize 2D workloads and prefer an end-of-life part with established drivers. For anyone building a new laptop, the RTX 5060 Mobile is the clear choice based on benchmark results. For desktop upgrades, the RX 6600 XT holds its own in legacy DirectX tests but lags in modern workloads.

Architecture Differences

The architectural gap between these two GPUs is substantial. The AMD Radeon RX 6600 XT uses the Navi 23 chip built on RDNA 2.0 architecture, fabricated on a 7 nm process at TSMC. The NVIDIA GeForce RTX 5060 Mobile uses the GB206 chip based on Blackwell 2.0 architecture, also from TSMC but on a 5 nm process. This node difference is significant: the NVIDIA chip packs 21,900 million transistors into a 181 mm² die, while the AMD chip has 11,060 million transistors on a 237 mm² die. The transistor density tells the story: 121.0M per mm² for NVIDIA versus 46.7M per mm² for AMD.

The compute configuration differs markedly. The RTX 5060 Mobile has 3328 shading units, 104 TMUs, and 48 ROPs. The RX 6600 XT has 2048 shading units, 128 TMUs, and 64 ROPs. This means AMD has more texture units and ROPs, but NVIDIA has more shading units. The ray tracing hardware also differs: AMD has 32 RT cores, while NVIDIA has 26 RT cores. Crucially, the NVIDIA part includes 104 tensor cores, while the AMD card has none listed.

Memory technology is another differentiator. Both have 8 GB, but the AMD uses GDDR6 with a 128-bit bus delivering 256.0 GB/s bandwidth. The NVIDIA uses GDDR7 on a 128-bit bus delivering 384.0 GB/s, which is 50% more bandwidth. Clock speeds tell a contrasting story: the AMD card boosts to 2589 MHz, while the NVIDIA part boosts to only 1455 MHz. The AMD card's higher clocks contribute to its higher pixel rate of 165.7 GPixel/s versus 69.84 GPixel/s for NVIDIA, and texture rate of 331.4 GTexel/s versus 151.3 GTexel/s. Despite these advantages, the NVIDIA part achieves higher FP32 compute of 9.684 TFLOPS, close to AMD's 10.60 TFLOPS, and its FP16 is 9.684 TFLOPS (1:1) versus AMD's 21.21 TFLOPS (2:1).

The bus interface also differs: AMD uses PCIe 4.0 x8, while NVIDIA uses PCIe 5.0 x16. The NVIDIA part is an integrated form factor (IGP) with no power connectors, while the AMD card is dual-slot with a single 8-pin connector.

Head-to-Head Benchmarks

The benchmark results reveal where each architecture excels. The biggest win for NVIDIA is in 3DMark Steel Nomad DX12, with a score of 3013.5 against 1804, a 40.1% lead. This modern DirectX 12 workload clearly favors the Blackwell architecture and its higher memory bandwidth. Passmark DirectX 12 shows a similar trend, with NVIDIA scoring 87 versus 61, a 29.9% advantage.

In compute workloads, NVIDIA maintains its lead but by smaller margins. Geekbench OpenCL shows NVIDIA at 96969 versus 80503, a 17% difference. Geekbench Vulkan shows a 24.9% gap, with NVIDIA at 96451 and AMD at 72417. Passmark GPU Compute is nearly tied: NVIDIA scores 7607 versus 7520, just 1.1% ahead.

Legacy DirectX tests show narrower gaps. Passmark DirectX 10 has NVIDIA at 119 versus 109, an 8.4% lead. Passmark DirectX 11 has NVIDIA at 168 versus 163, just a 3% difference. Passmark DirectX 9 shows NVIDIA at 203 versus 194, a 4.4% gap. These smaller margins suggest AMD's older architecture remains competitive in older APIs.

The overall Passmark G3D score favors NVIDIA at 18852 versus 16461, a 12.7% lead. The single AMD win is Passmark G2D, where AMD scores 912 against 876, a 4.1% advantage. This 2D performance edge is notable for desktop productivity tasks.

The average benchmark scores from the database place the AMD card at 24442 and the NVIDIA at 22435, with the AMD card ranking in the 70th percentile versus the NVIDIA's 67th. This is counterintuitive given NVIDIA's head-to-head dominance, but it reflects the different benchmark suites and the fact that the AMD card's nearest rivals include the GTX 1630 (0.7% ahead), GTX 780 Ti (0.8% ahead), and RTX 2080 SUPER (1.1% ahead), while the NVIDIA mobile part's rivals include the RX 7700 XT (0.5% ahead) and RTX 4060 Mobile (1.3% ahead).

Where Each One Wins

The NVIDIA GeForce RTX 5060 Mobile wins in every scenario that stresses modern graphics APIs and compute workloads. Its 40.1% lead in 3DMark Steel Nomad DX12 and 29.9% lead in Passmark DirectX 12 make it the clear choice for current-generation gaming and DX12-optimized applications. The 24.9% advantage in Geekbench Vulkan indicates strong performance in Vulkan-based titles and compute. The 17% lead in OpenCL and 12.7% lead in Passmark G3D reinforce its position for general 3D rendering and GPU-accelerated tasks. Its 384.0 GB/s memory bandwidth and tensor cores suggest it is better suited for AI-related workloads, even if the database does not directly measure those.

The AMD Radeon RX 6600 XT wins only in Passmark G2D, with a 4.1% edge. This makes it the better choice for 2D desktop workloads, legacy applications, or any scenario where the Passmark G2D score is representative. Its higher pixel rate (165.7 GPixel/s versus 69.84 GPixel/s) and texture rate (331.4 GTexel/s versus 151.3 GTexel/s) indicate raw fill-rate advantages, though these do not translate to wins in the recorded benchmarks. The AMD card's higher base and boost clocks (1968 MHz and 2589 MHz versus 952 MHz and 1455 MHz) suggest it may have advantages in clock-sensitive workloads, but the database does not show a win outside of G2D.

For laptop users, the RTX 5060 Mobile is the only realistic option given its 45 W TDP and IGP form factor. For desktop users, the RX 6600 XT remains an end-of-life product with a 160 W TDP, and its nearest rivals in the database include the GTX 1630 (0.7% behind) and RTX 2080 SUPER (1.1% behind), showing it is competitive within its desktop class.
