AMD Radeon RX 7900 GRE vs Intel Arc B770 Comparison

Head-to-Head Benchmarks

The benchmark database contains a full suite of recorded results for the AMD Radeon RX 7900 GRE, while the Intel Arc B770 currently has no benchmark entries listed. This makes a direct score-for-score comparison impossible at this time. The RX 7900 GRE posts an average benchmark score of 32,456 across its suite, placing it in the 77th percentile of all GPUs tracked. The Arc B770 holds a 50th percentile ranking, but with an average score of 0 due to the absence of recorded measurements.

Looking at the RX 7900 GRE's individual results, the strongest showing comes in Geekbench OpenCL with a score of 175,758, followed by Geekbench Vulkan at 99,850. In the 3DMark Steel Nomad DX12 test, it records 4,814 points. The Passmark suite shows a G3D score of 27,089 and a GPU compute score of 15,016. The DirectX legacy tests are notably lower: DirectX 9 scores 310, DirectX 11 scores 300, and DirectX 10 scores 139, with DirectX 12 at 107. The 2D graphics score is 1,180.

The nearest rivals in the database for the RX 7900 GRE are all AMD workstation or older gaming cards. The AMD FirePro S10000 averages 32,388, which is 0.2% behind the RX 7900 GRE. The AMD FirePro S9300 X2 averages 32,540, putting it 0.3% ahead. The AMD Radeon RX 590 GME averages 32,601, which is 0.4% ahead. The AMD Radeon Pro 570X averages 32,176, sitting 0.9% behind. These deltas are all within a single percentage point, indicating that the RX 7900 GRE sits in a tightly clustered performance band relative to these older parts.

Since the Arc B770 has no recorded benchmarks, the head-to-head wins column shows zero victories for either card. The database currently cannot substantiate any performance advantage for the Intel card, nor can it confirm the RX 7900 GRE's lead beyond its own absolute scores. What the data does show is that the RX 7900 GRE delivers a substantial compute-oriented result in OpenCL, more than doubling its Vulkan score, which suggests strong raw throughput in general-purpose workloads.

Where Each One Wins

For the AMD Radeon RX 7900 GRE, the recorded benchmarks indicate its strengths lie in modern API workloads and compute-heavy tasks. The Geekbench OpenCL score of 175,758 versus the Vulkan score of 99,850 shows a clear advantage in OpenCL compute environments. The 3DMark Steel Nomad DX12 result of 4,814 points confirms solid performance in current-generation DirectX 12 gaming scenarios. The Passmark G3D score of 27,089 and GPU compute score of 15,016 reinforce that the card handles both rasterization and compute duties competently.

The legacy DirectX tests tell a different story. Scores of 310 in DirectX 9, 300 in DirectX 11, 139 in DirectX 10, and 107 in DirectX 12 (Passmark's specific implementation) are all low in absolute terms. This pattern suggests the RX 7900 GRE's architecture prioritizes modern workloads over older API paths, which is consistent with its RDNA 3.0 design. Users running older titles on legacy APIs would not see the same relative performance as those using current engines.

For the Intel Arc B770, there are no benchmark wins recorded in the database. The card's specifications indicate it has 4,096 shading units, 256 TMUs, and 128 ROPs, with 32 ray tracing cores. Its FP32 throughput is rated at 19.66 TFLOPS, and FP16 at 39.32 TFLOPS. These figures are lower than the RX 7900 GRE's 5,120 shading units, 320 TMUs, 160 ROPs, 80 ray tracing cores, and 45.98 TFLOPS FP32. Without recorded test results, the database cannot assign any benchmark-based use-case wins to the Arc B770.

The RX 7900 GRE also wins on memory bandwidth with 576.0 GB/s versus the Arc B770's 512.0 GB/s, both using 16 GB of GDDR6 on a 256-bit bus. The AMD card's higher texture rate of 718.4 GTexel/s and pixel rate of 359.2 GPixel/s compared to the Intel card's 614.4 GTexel/s and 307.2 GPixel/s point to advantages in fill-rate-bound scenarios, though these are specification-derived rather than benchmark-verified.

The Verdict

The data in the database clearly favors the AMD Radeon RX 7900 GRE, but only because it has a complete set of measurements while the Intel Arc B770 has none. The RX 7900 GRE's average benchmark score of 32,456 and 77th percentile ranking provide a concrete reference point. The Arc B770's 50th percentile is a placeholder value tied to an average score of zero, which reflects missing data rather than actual performance.

Buyers seeking a card with verified benchmark results should consider the RX 7900 GRE. Its OpenCL score of 175,758 and Vulkan score of 99,850 demonstrate strong compute capability, and the 3DMark Steel Nomad result of 4,814 confirms modern gaming performance. The nearest rival deltas, all within 0.9% of the RX 7900 GRE's average, show that it sits in a competitive band against older AMD workstation cards, though those are not direct contemporaries.

The Arc B770, with its 225 W TDP and 550 W suggested PSU, draws less power than the RX 7900 GRE's 260 W and 600 W suggestion. It also uses a smaller die at 368 mm² versus 529 mm², though transistor counts for the Intel card are listed as unknown. These specification differences do not translate into benchmark advantages without recorded scores. The database cannot recommend the Arc B770 for any specific workload based on measurements, as none exist.

For users who prioritize verified performance data, the RX 7900 GRE is the only card in this comparison with recorded results. The Arc B770 remains an unmeasured entity in the database, and any performance claims about it would be speculative rather than data-driven.
