GPU Comparison

AMD Radeon VII and NVIDIA GeForce RTX 5080 represent two distinct eras of GPU design, separated by six years of architectural evolution. The data shows a decisive performance gap, with the RTX 5080 winning all three head-to-head benchmark comparisons, yet the Radeon VII still holds a higher overall percentile ranking. This creates an interesting paradox where the newer card dominates in raw compute tests but the older card maintains a better position in the aggregate database ranking.

Head-to-Head Benchmarks

The NVIDIA GeForce RTX 5080 delivers a commanding sweep across every shared benchmark test. In 3DMark Steel Nomad DX12, the RTX 5080 scores 8637 points against the Radeon VII’s 2304 points, a delta of -73.3% from the AMD card’s perspective. This is the largest margin of victory in the comparison, indicating that the Blackwell architecture’s modern feature set provides a massive advantage in contemporary DirectX 12 workloads. The RTX 5080’s score is more than 3.7 times higher, which translates to a generational leap that goes far beyond simple clock speed improvements.

The compute-oriented tests tell a similar story, though with slightly narrower margins. In Geekbench OpenCL, the RTX 5080 posts 235901 points versus 91947 for the Radeon VII, a -61% delta. The Vulkan test shows the RTX 5080 at 255450 points against 91788, a -64.1% delta. These results indicate that the RTX 5080’s 10752 shading units and 336 tensor cores provide a substantial throughput advantage over the Radeon VII’s 3840 shading units, even when accounting for the older card’s high-bandwidth HBM2 memory.

The Radeon VII’s best showing comes in the Geekbench OpenCL test, where its 1.02 TB/s memory bandwidth helps narrow the gap slightly compared to the 3DMark result. However, the RTX 5080 still maintains a commanding lead in every scenario. The data shows no benchmark where the Radeon VII emerges victorious, with the wins tally at 0 for AMD and 3 for NVIDIA. The smallest relative gap remains the OpenCL test at -61%, which suggests that the Radeon VII’s compute capabilities are relatively stronger than its gaming-focused performance, but still far behind the newer card’s raw processing power.

Where Each One Wins

The RTX 5080 is the clear winner in every measurable category from the head-to-head data. Its 3DMark Steel Nomad DX12 score of 8637 versus 2304 demonstrates superior gaming performance in modern DirectX 12 titles, which is expected given its 84 RT cores and DirectX 12 Ultimate support. The card’s Vulkan score of 255450 indicates strong cross-platform API performance, making it suitable for both Windows gaming and Vulkan-based applications. The OpenCL score of 235901 positions it as a capable compute workhorse for GPU-accelerated tasks.

The Radeon VII, despite losing all direct comparisons, still holds advantages in certain aggregate metrics. Its average benchmark score of 66004 places it in the 90th percentile of all GPUs, compared to the RTX 5080’s 87th percentile with an average score of 56083. This suggests that the Radeon VII performs relatively better across the broader benchmark suite tracked by the database, even though it loses the specific tests shared with the RTX 5080. The Radeon VII’s nearest rivals include the NVIDIA Tesla T4 at -1.1% and the NVIDIA Tesla P40 at +1.4%, indicating it sits in a competitive position among professional and compute-focused cards.

The RTX 5080’s nearest rivals tell a different story. It sits close to the AMD Radeon RX 9070 GRE at -2.2%, meaning the RX 9070 GRE actually scores higher on average. The RTX 5080 also edges out the AMD Radeon 8060S by 0.6% and the AMD Radeon RX 6750 GRE 12 GB by 0.7%. This clustering suggests that the RTX 5080’s average benchmark score is more about consistency across many tests rather than dominance in any single one, whereas the Radeon VII’s higher percentile reflects strength in a narrower set of compute-heavy workloads.

The Verdict

Based strictly on the benchmark data, the NVIDIA GeForce RTX 5080 is the superior performer in every shared test. Users seeking maximum performance in 3DMark Steel Nomad DX12, Geekbench OpenCL, or Geekbench Vulkan should choose the RTX 5080 without hesitation. The card’s 56.28 TFLOPS FP32 performance and 879.3 GTexel/s texture rate dwarf the Radeon VII’s 13.44 TFLOPS and 420.0 GTexel/s, making it the obvious choice for compute-intensive applications and modern gaming.

However, the Radeon VII’s higher percentile ranking and better average benchmark score indicate that it may still be relevant in specific legacy or compute-oriented workloads where its 16 GB of HBM2 memory with 1.02 TB/s bandwidth provides unique advantages. The card’s 90th percentile placement versus the RTX 5080’s 87th suggests that the aggregate database ranking favors the older AMD card, possibly due to its strength in non-gaming compute benchmarks that are not part of the head-to-head comparison.

The RTX 5080’s launch MSRP is 999 USD, while the Radeon VII launched at 699 USD. Both cards feature 16 GB of memory, but the RTX 5080 uses GDDR7 on a 256-bit bus for 960.0 GB/s bandwidth, while the Radeon VII uses HBM2 on a 4096-bit bus for 1.02 TB/s. The RTX 5080’s higher bandwidth per watt and modern architecture make it the better choice for users who prioritize current-generation gaming and compute workloads, while the Radeon VII may appeal to those running older software that benefits from its specific hardware characteristics.

The two cards come from fundamentally different architectural generations. The AMD Radeon VII uses the Vega 20 chip built on GCN 5.1 architecture, manufactured on TSMC’s 7 nm process with 13,230 million transistors on a 331 mm² die. This results in a transistor density of 40.0M per mm². In contrast, the NVIDIA GeForce RTX 5080 uses the GB203 chip built on Blackwell 2.0 architecture, manufactured on TSMC’s 5 nm process with 45,600 million transistors on a 378 mm² die, achieving a transistor density of 120.6M per mm².

The clock speeds differ substantially. The Radeon VII operates at a base clock of 1400 MHz and a boost clock of 1750 MHz, with memory running at 1000 MHz (2 Gbps effective). The RTX 5080 runs at a base clock of 2295 MHz and a boost clock of 2617 MHz, with memory at 1875 MHz (30 Gbps effective). These higher clocks contribute significantly to the RTX 5080’s performance advantage, with FP32 computing reaching 56.28 TFLOPS versus the Radeon VII’s 13.44 TFLOPS. The FP16 performance also differs: the Radeon VII achieves 26.88 TFLOPS at a 2:1 ratio, while the RTX 5080 delivers 56.28 TFLOPS at a 1:1 ratio.

The feature sets reflect their respective eras. The Radeon VII supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3, while the RTX 5080 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5080 includes 84 RT cores and 336 tensor cores for ray tracing and AI acceleration, features entirely absent from the Radeon VII. The pixel rate and texture rate also favor the newer card: 293.1 GPixel/s and 879.3 GTexel/s versus 112.0 GPixel/s and 420.0 GTexel/s respectively.

The power and connectivity profiles diverge as well. The Radeon VII has a TDP of 295 W with dual 8-pin power connectors and a suggested 600 W PSU, while the RTX 5080 has a TDP of 360 W with a single 16-pin connector and a suggested 750 W PSU. The Radeon VII uses PCIe 3.0 x16, while the RTX 5080 uses PCIe 5.0 x16. Display outputs differ with the Radeon VII offering HDMI 2.0b and DisplayPort 1.4a, while the RTX 5080 offers HDMI 2.1b and DisplayPort 2.1b. The Radeon VII measures 280 mm in length, 125 mm in height, and 40 mm in width, while the RTX 5080 is slightly larger at 304 mm, 137 mm, and 40 mm respectively.
