AMD Radeon RX 7600M XT vs NVIDIA GeForce GTX 1080 Comparison

The AMD Radeon RX 7600M XT and NVIDIA GeForce GTX 1080 are separated by seven years of GPU architecture, and the benchmark data shows a split decision: each card wins exactly five of the ten head-to-head tests. The AMD card, built on RDNA 3.0, dominates in modern DirectX 12 and compute workloads, while the older Pascal-based GTX 1080 retains advantages in legacy DirectX tests and raw rasterization throughput. The average benchmark scores tell a similar story, with the RX 7600M XT averaging 12,710 points against the GTX 1080's 11,960, placing both within one percentile of each other (52nd vs 51st percentile across all GPUs).

Head-to-Head Benchmarks

The most decisive victory for the AMD Radeon RX 7600M XT comes in 3DMark Steel Nomad DX12, where it scores 2,048 against the GTX 1080's 1,560—a 31.3% advantage. This is the single largest margin in either direction across all ten tests and highlights how the newer architecture handles modern DirectX 12 workloads. The AMD card also posts a commanding 46.2% lead in Geekbench OpenCL, scoring 74,869 versus 51,204, which represents its biggest win overall.

The RX 7600M XT continues its modern-workload dominance with a 10.5% win in Passmark DirectX 11 (137 vs 124) and a narrower 5.5% edge in Passmark DirectX 12 (58 vs 55). Even in 2D performance, the AMD card edges ahead with a 0.7% margin in Passmark G2D (894 vs 888), though this is effectively a tie.

The NVIDIA GeForce GTX 1080 counterattacks in legacy and compute-heavy benchmarks. Its largest win is 18.3% in Passmark DirectX 10 (93 vs 76), followed closely by a 17.1% advantage in Passmark DirectX 9 (211 vs 175). The GTX 1080 also takes Passmark G3D with a 10.8% lead (15,586 vs 13,907) and Passmark GPU Compute with a 6.2% margin (7,614 vs 7,140). In Geekbench Vulkan, the NVIDIA card scores 30,398 against the AMD card's 27,793, an 8.6% advantage.

Interestingly, the two cards split the five Passmark sub-tests evenly, with AMD winning DirectX 11, DirectX 12, and G2D, while NVIDIA wins DirectX 9, DirectX 10, G3D, and GPU Compute. The pattern is clear: the newer AMD architecture excels at the latest API levels, while the older NVIDIA card retains strengths in older DirectX versions and general 3D rasterization.

Where Each One Wins

The AMD Radeon RX 7600M XT is the clear choice for modern DirectX 12 gaming and compute-heavy applications. Its 31.3% lead in 3DMark Steel Nomad DX12 and 46.2% lead in Geekbench OpenCL indicate strong performance in current-generation game engines and GPGPU workloads that leverage the latest API features. The card also wins in DirectX 11, which remains the most common API for many PC games, making it a practical option for contemporary titles.

The NVIDIA GeForce GTX 1080 wins where older APIs and traditional rasterization matter. Its 18.3% and 17.1% leads in DirectX 10 and DirectX 9 respectively make it the better choice for legacy games and applications that rely on those older interfaces. The 10.8% advantage in Passmark G3D suggests stronger overall 3D rendering capability in standardized tests, while the 6.2% lead in GPU compute indicates an edge in certain compute workloads. The Vulkan result (8.6% ahead) shows the NVIDIA card still holds its own in cross-platform graphics.

The respective benchmark averages place the RX 7600M XT at the 52nd percentile and the GTX 1080 at the 51st percentile, making them statistically comparable overall. The AMD card's nearest rivals include the GTX 670 (0.5% behind), Tesla K20Xm (0.7% ahead), and GTX 590 (0.9% behind), while the GTX 1080 sits closest to the GTX 960A (0.3% behind), RX 6500 XT (1% ahead), and GTX 1660 (2.4% ahead).

Architecture Differences

The two GPUs represent fundamentally different design philosophies separated by two process generations. The AMD Radeon RX 7600M XT uses the Navi 33 chip on a 6 nm TSMC process, packing 13,300 million transistors into a 204 mm² die. This yields a transistor density of 65.2 million per mm². The GTX 1080 uses the GP104 chip on a 16 nm TSMC process, with 7,200 million transistors spread across a much larger 314 mm² die, giving a density of just 22.9 million per mm². The AMD card achieves more than double the transistor density of the NVIDIA chip.

The RX 7600M XT features 2,048 shading units, 128 texture mapping units, and 64 ROPs, along with 32 dedicated ray tracing cores. The GTX 1080 has 2,560 shading units, 160 TMUs, and 64 ROPs, but no ray tracing cores. Despite having fewer shading units, the AMD card achieves higher raw throughput thanks to its RDNA 3.0 architecture: 20.23 TFLOPS FP32 versus 8.873 TFLOPS for the GTX 1080. The FP16 comparison is even more stark, with the AMD card delivering 40.45 TFLOPS (2:1 ratio) versus 138.6 GFLOPS (1:64 ratio) for NVIDIA.

Memory configurations differ in bus width and bandwidth. The RX 7600M XT uses 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s bandwidth at 18 Gbps effective speed. The GTX 1080 also has 8 GB, but uses GDDR5X on a 256-bit bus, achieving 320.3 GB/s at 10 Gbps effective. The NVIDIA card's wider bus gives it an 11% bandwidth advantage, though the newer GDDR6 memory in the AMD card operates at nearly double the effective speed.

Power and physical characteristics diverge significantly. The RX 7600M XT has a 120 W TDP and is designed as an IGP (integrated graphics processor) with no power connectors and portable-device-dependent display outputs. The GTX 1080 carries a 180 W TDP, requires a dual-slot cooler with a single 8-pin power connector, and a 450 W suggested PSU. It measures 267 mm in length, 112 mm in height, and 40 mm in width, with display outputs of 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.4a. The AMD card supports PCIe 4.0 x16, while the NVIDIA card uses PCIe 3.0 x16.

The Verdict

The data presents a clear generational trade-off. The AMD Radeon RX 7600M XT is the superior choice for anyone running modern DirectX 12 games or compute-heavy applications. Its 31.3% lead in 3DMark Steel Nomad DX12 and 46.2% lead in Geekbench OpenCL demonstrate a significant advantage in current-generation workloads. The inclusion of 32 ray tracing cores and DirectX 12 Ultimate support positions it for future titles, while its 6 nm node and 120 W TDP make it dramatically more power-efficient than the older NVIDIA card.

The NVIDIA GeForce GTX 1080 remains relevant for specific use cases. Its wins in DirectX 9 (17.1%), DirectX 10 (18.3%), Passmark G3D (10.8%), and GPU Compute (6.2%) indicate it handles legacy APIs and certain rasterization tasks better than the newer AMD card. The 8.6% Vulkan advantage also matters for cross-platform development. The higher memory bandwidth (320.3 GB/s vs 288.0 GB/s) and larger shading unit count (2,560 vs 2,048) contribute to these wins.

For a desktop user playing contemporary titles, the RX 7600M XT's architecture provides better raw throughput (20.23 TFLOPS vs 8.873 TFLOPS FP32) and superior API support. The GTX 1080, now end-of-life, serves best in older game libraries and compute scenarios where its strengths align. The 52nd versus 51st percentile ranking confirms they are closely matched overall, but the direction of development favors AMD's modern design. The GTX 1080's launch MSRP was 599 USD, though that figure is historical context rather than a current comparison point.
