AMD Radeon RX 7900 GRE vs Intel Arc Pro B370 Comparison

AMD Radeon RX 7900 GRE and Intel Arc Pro B370 occupy different tiers of the graphics hardware spectrum, and the recorded data shows they are not direct competitors in raw performance. The RX 7900 GRE is a discrete add-in board from the Radeon RX 7000 series, while the Arc Pro B370 is an integrated graphics processor (IGP) from Intel’s Panther Lake generation. This analysis separates the two based on benchmark results, architecture differences, and specification gaps, using only the database entries.

Where Each One Wins

The RX 7900 GRE wins every measurable performance category in the database. Its benchmark scores are substantial: in 3DMark Steel Nomad DX12, it records 4814 points, while the Arc Pro B370 has no entries in any benchmark test, including 3DMark, Geekbench, or Passmark suites. The Arc Pro B370’s average benchmark score is 0, and its percentile ranking among all GPUs is 50, meaning it sits at the median of the distribution but has no actual score data to confirm performance.

The RX 7900 GRE delivers a Passmark G3D score of 27089, a Passmark GPU Compute score of 15016, and a Geekbench OpenCL score of 175758. These numbers place it in the 77th percentile of all GPUs in the database. The Arc Pro B370, by contrast, has no recorded scores, so the database shows no wins for it in any test. The head-to-head benchmark list is empty, and the win counts are zero for both cards, but the benchmark data for the RX 7900 GRE provides concrete figures that the Arc Pro B370 lacks entirely.

For use cases, the RX 7900 GRE is positioned for demanding workloads: discrete graphics with 16 GB of dedicated GDDR6 memory, 5120 shading units, and a 260 W power envelope. The Arc Pro B370 is an IGP with system-shared memory, 1280 shading units, and a 25 W TDP, designed for portable or low-power devices. The data indicates the RX 7900 GRE wins in every scenario where discrete rendering or compute is required, while the Arc Pro B370’s role is limited to integrated graphics in systems where add-in cards are not present.

Architecture Differences

The two GPUs stem from different architectural lineages. The RX 7900 GRE uses the Navi 31 chip, built on RDNA 3.0 architecture, with the codename Plum Bonito. It is fabricated on a 5 nm process at TSMC, with 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1 million per square millimeter. The Arc Pro B370 uses the Panther Lake chip, based on Xe3-LPG architecture, with no codename listed. It is built on a 3 nm process at Intel, but the transistor count and die size are listed as unknown, so no density figure is available.

The RX 7900 GRE has a base clock of 1287 MHz, a boost clock of 2245 MHz, and a game clock of 1880 MHz. Its memory runs at 2250 MHz, with 18 Gbps effective speed. The Arc Pro B370 has a base clock of 300 MHz and a boost clock of 2400 MHz, with no game clock listed. Its memory is system-shared, so the clock and bandwidth are system dependent. The RX 7900 GRE provides 576.0 GB/s of dedicated bandwidth over a 256 bit bus, while the Arc Pro B370 has no dedicated memory bus width.

Architecturally, the RX 7900 GRE uses RDNA 3.0 with 80 ray tracing cores and 160 ROPs, while the Arc Pro B370 uses Xe3-LPG with 10 ray tracing cores and 20 ROPs. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The RX 7900 GRE has a dual-slot form factor, requires two 8-pin power connectors, and suggests a 600 W power supply. The Arc Pro B370 is an IGP with no power connectors and no suggested PSU, fitting directly into a processor package.

The RX 7900 GRE’s predecessor is Navi II, and its successor is Navi IV. The Arc Pro B370’s predecessor is HD Graphics-WM, with no successor listed. The RX 7900 GRE was released on 2023-07-26, while the Arc Pro B370 has a release date of 2026-01-26, indicating a later introduction for the Intel part.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two GPUs. The RX 7900 GRE has ten benchmark scores, while the Arc Pro B370 has none. This lack of direct comparison data means the analysis relies on the absolute scores from the RX 7900 GRE and the absence of scores for the Arc Pro B370.

The RX 7900 GRE’s strongest recorded results are in compute and general graphics. Its Geekbench OpenCL score of 175758 shows a large lead over any potential integrated solution, given that the Arc Pro B370 has no comparable figure. In 3DMark Steel Nomad DX12, the RX 7900 GRE scores 4814, which is a demanding modern workload, while the Arc Pro B370 has no entry. Passmark G3D at 27089 and Passmark GPU Compute at 15016 reinforce the discrete card’s capability.

The RX 7900 GRE also shows strong legacy DirectX performance: Passmark DirectX 9 scores 310, DirectX 10 scores 139, DirectX 11 scores 300, and DirectX 12 scores 107. These numbers are lower than the newer 3DMark result but still represent measurable performance. The Arc Pro B370, with zero benchmark entries, cannot be compared on any of these tests. The nearest rivals for the RX 7900 GRE are AMD FirePro S10000 (avg score 32388, delta 0.2%), AMD FirePro S9300 X2 (avg score 32540, delta -0.3%), AMD Radeon RX 590 GME (avg score 32601, delta -0.4%), and AMD Radeon Pro 570X (avg score 32176, delta 0.9%). These rivals are all within 1% of the RX 7900 GRE’s average benchmark score of 32456, but none of them are the Arc Pro B370.

For the Arc Pro B370, the average benchmark score is 0 and its percentile is 50, but with no data points, this percentile is not backed by any test result. The RX 7900 GRE’s percentile of 77 places it above the majority of GPUs in the database, while the Arc Pro B370’s 50th percentile is unverified without scores.

The Verdict

The data shows a clear separation: the RX 7900 GRE is a high-performance discrete GPU with a full suite of benchmark results, while the Arc Pro B370 is an integrated processor with no recorded performance data. For users who need dedicated graphics, the RX 7900 GRE provides 5120 shading units, 16 GB of GDDR6 memory, and 45.98 TFLOPS of FP32 compute. Its 77th percentile ranking and average benchmark score of 32456 confirm it as a capable part for gaming and compute workloads.

The Arc Pro B370, with 1280 shading units, 25 W TDP, and system-shared memory, is not designed for the same tasks. Its boost clock of 2400 MHz is higher than the RX 7900 GRE’s 2245 MHz, but the base clock of 300 MHz and lack of dedicated memory bandwidth indicate a much lower sustained performance profile. The Arc Pro B370 is suitable for low-power integrated graphics in portable devices, where the RX 7900 GRE’s 260 W TDP and dual-slot size would not fit.

Choice depends on the use case. The RX 7900 GRE is for desktop systems requiring discrete rendering, with a launch MSRP of 549 USD. The Arc Pro B370 is for integrated graphics in systems where add-in cards are not an option, with no pricing data available. The RX 7900 GRE wins all measurable benchmarks, but the Arc Pro B370 offers a different form factor and power profile. The database does not provide any performance scores for the Arc Pro B370, so any comparison in raw speed is one-sided. The RX 7900 GRE is the only part with verified performance data, and it dominates every category where numbers exist.
