AMD Radeon RX 7900 GRE vs Intel Arc Pro B65 Comparison

Head-to-Head Benchmarks

The database currently contains a complete benchmark profile for the AMD Radeon RX 7900 GRE, while the Intel Arc Pro B65 has no recorded benchmark scores. This asymmetry directly shapes the comparative analysis available in the database.

The AMD Radeon RX 7900 GRE delivers an average benchmark score of 32456 across all recorded tests. Its percentile ranking places it at 77, meaning it outperforms 77% of all GPUs tracked in the database. The nearest rivals in the database provide useful context for this score. The AMD FirePro S10000 records an average score of 32388, which is 0.2% below the RX 7900 GRE. The AMD FirePro S9300 X2 posts an average score of 32540, putting it 0.3% ahead. The AMD Radeon RX 590 GME achieves 32601, a 0.4% advantage. The AMD Radeon Pro 570X trails with 32176, a 0.9% deficit. These deltas indicate that the RX 7900 GRE sits in a tightly grouped performance band, with all four nearest rivals within roughly one percentage point of its average score.

Individual benchmark results for the RX 7900 GRE show its strongest showing in the 3DMark Steel Nomad DX12 test with a score of 4814. The Geekbench OpenCL result reaches 175758, while the Geekbench Vulkan score is 99850. In the Passmark suite, the GPU compute test produces a score of 15016, and the G3D test reaches 27089. The DirectX 11 test scores 300, the DirectX 9 test scores 310, the DirectX 10 test scores 139, and the DirectX 12 test scores 107. The G2D test records 1180. The Intel Arc Pro B65 has no entries in any of these tests, so no head-to-head wins can be assigned to either product.

The recorded data indicates that the RX 7900 GRE produces a 0.2% higher average score than the AMD FirePro S10000 and a 0.9% higher average score than the AMD Radeon Pro 570X. It trails the AMD FirePro S9300 X2 by 0.3% and the AMD Radeon RX 590 GME by 0.4%. These margins are small enough that run-to-run variation could plausibly reorder these products, but the database shows the RX 7900 GRE holding a slight edge over two of its four nearest rivals. The Intel Arc Pro B65 cannot be placed in this ranking because it lacks any measured scores, and its percentile of 50 with an average score of 0 reflects an unpopulated profile rather than an actual performance level.

Architecture Differences

The two GPUs diverge sharply at the architectural level. The AMD Radeon RX 7900 GRE uses the Navi 31 chip built on RDNA 3.0 architecture, with the codename Plum Bonito. It belongs to the Navi III generation within the RX 7000 series. The Intel Arc Pro B65 uses the BMG-G21 chip built on Xe2-HPG architecture, from the Battlemage Pro Series generation. Both are fabricated by TSMC on a 5 nm process, but the similarity ends there.

The transistor counts differ substantially. The RX 7900 GRE packs 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1 million transistors per square millimeter. The Arc Pro B65 contains 19,600 million transistors on a 272 mm² die, resulting in a density of 72.1 million transistors per square millimeter. The RX 7900 GRE therefore uses nearly three times the transistor budget and a die roughly twice the area, while achieving a higher packing density.

Compute resources follow the same pattern. The RX 7900 GRE features 5120 shading units, 320 texture mapping units, 160 render output units, and 80 ray tracing cores. The Arc Pro B65 halves all of these: 2560 shading units, 160 TMUs, 80 ROPs, and 20 ray tracing cores. The RX 7900 GRE also leads in pixel throughput at 359.2 GPixel/s versus 192.0 GPixel/s, and in texture throughput at 718.4 GTexel/s versus 384.0 GTexel/s. Floating point performance shows the same hierarchy, with the RX 7900 GRE delivering 45.98 TFLOPS FP32 and 91.96 TFLOPS FP16, while the Arc Pro B65 delivers 12.29 TFLOPS FP32 and 24.58 TFLOPS FP16.

Clock behavior differs in an interesting way. The RX 7900 GRE has a base clock of 1287 MHz, a boost clock of 2245 MHz, and a game clock of 1880 MHz. The Arc Pro B65 runs a fixed 2400 MHz for both base and boost, with no separate game clock listed. The memory clocks are similar, with the RX 7900 GRE at 2250 MHz (18 Gbps effective) and the Arc Pro B65 at 2375 MHz (19 Gbps effective). Neither product lists tensor cores in the database.

The Verdict

The recorded data presents a clear performance hierarchy, but only for one side. The AMD Radeon RX 7900 GRE has a full benchmark profile with an average score of 32456 and a 77th percentile ranking. The Intel Arc Pro B65 has no benchmark entries, an average score of 0, and a 50th percentile placeholder. No direct comparison can be made from measured results because the database contains no head-to-head tests for these two products and no individual scores for the Arc Pro B65.

From the architectural data alone, the RX 7900 GRE holds advantages that would typically translate into higher rasterization throughput. It has double the shading units, TMUs, and ROPs, and quadruple the ray tracing cores. Its FP32 throughput of 45.98 TFLOPS is roughly 3.7 times the Arc Pro B65's 12.29 TFLOPS. Pixel rate and texture rate also favor the RX 7900 GRE by similar margins. The Arc Pro B65 counters with a larger memory capacity of 32 GB versus 16 GB, a slightly higher memory bandwidth of 608.0 GB/s versus 576.0 GB/s, and a higher fixed clock of 2400 MHz versus the RX 7900 GRE's boost of 2245 MHz.

The power profiles differ as well. The RX 7900 GRE carries a TDP of 260 W with a suggested 600 W power supply and two 8-pin connectors. The Arc Pro B65 has a TDP of 200 W, a suggested 550 W power supply, and a single 8-pin connector. The Arc Pro B65 also uses PCIe 5.0 x16 while the RX 7900 GRE uses PCIe 4.0 x16. The RX 7900 GRE offers a wider display output set with 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C, while the Arc Pro B65 provides 4x DisplayPort 2.1.

Selecting between these products depends entirely on whether the user prioritizes raw compute throughput or memory capacity. The RX 7900 GRE dominates in shading, texturing, ray tracing, and pixel output. The Arc Pro B65 offers twice the memory and slightly higher bandwidth in a lower power envelope. Without measured benchmarks for the Arc Pro B65, any performance conclusion for that product must remain provisional.
