AMD Radeon RX 7800 XT vs Intel Arc Pro B65 Comparison

AMD Radeon RX 7800 XT and Intel Arc Pro B65 are two very different GPUs aimed at different segments. The RX 7800 XT is a consumer gaming card from AMD’s Radeon RX 7000 series, built on the Navi 32 chip with RDNA 3.0 architecture. The Arc Pro B65 is a professional workstation card from Intel’s Battlemage Pro Series, using the BMG-G21 chip and Xe2-HPG architecture. The database contains benchmark results for the RX 7800 XT but no benchmark scores for the Arc Pro B65, so direct numerical comparisons rely on the recorded data for the AMD card and the architectural specifications for both.

Head-to-Head Benchmarks

The database records ten benchmark results for the AMD Radeon RX 7800 XT, while the Intel Arc Pro B65 has no recorded benchmark scores. This makes a direct head-to-head numerical comparison impossible from the measured data alone. However, the RX 7800 XT’s scores can be analyzed against its nearest rivals in the database, which include the NVIDIA GeForce GTX 1660, AMD Radeon Pro 5500M, NVIDIA Tesla K20c, and AMD Radeon RX 6500 XT.

The RX 7800 XT’s average benchmark score across all recorded tests is 11627. Its closest rival by average score is the NVIDIA GeForce GTX 1660, which has an average score of 11680, putting the RX 7800 XT 0.5% below that card. The AMD Radeon Pro 5500M has an average score of 11528, which places the RX 7800 XT 0.9% above it. The NVIDIA Tesla K20c averages 11479, with the RX 7800 XT 1.3% higher. The AMD Radeon RX 6500 XT has an average score of 11842, putting the RX 7800 XT 1.8% below it. These deltas are all within a narrow band of roughly two percentage points, indicating that the RX 7800 XT sits in a tightly contested performance tier according to the aggregate metric.

Looking at individual benchmark tests, the RX 7800 XT shows its strongest results in specific workloads. In the Geekbench Vulkan test, the RX 7800 XT scores 54228, which is its highest recorded score across all benchmarks. The PassMark G3D test yields a score of 24176, representing strong overall 3D graphics performance. The Geekbench OpenCL score is 18290, and the PassMark GPU Compute score is 13473. In the 3DMark Steel Nomad DX12 test, the RX 7800 XT scores 4157.

The PassMark suite reveals a wide variation across different DirectX versions. The DirectX 9 test scores 304, the DirectX 10 test scores 121, the DirectX 11 test scores 249, and the DirectX 12 test scores 93. The PassMark G2D score is 1177. These numbers show that the RX 7800 XT performs far better in older DirectX versions like DirectX 9 than in newer ones like DirectX 12, at least within the PassMark testing methodology.

The RX 7800 XT sits at the 51st percentile among all GPUs in the database, while the Arc Pro B65 is listed at the 50th percentile. This percentile difference is marginal. However, the Arc Pro B65 has an average benchmark score of 0 because no benchmark results are recorded for it in the database. This means the percentile for the Intel card is based on its specification profile rather than measured performance.

Where Each One Wins

Without recorded benchmarks for the Arc Pro B65, the use-case split must be inferred from the architectural data and the measured results available for the RX 7800 XT.

The AMD Radeon RX 7800 XT delivers 37.32 TFLOPS of FP32 compute and 37.32 TFLOPS of FP16 with a 1:1 ratio. It has 3840 shading units, 240 texture mapping units, and 96 raster operations pipelines. The card includes 60 ray tracing cores. Its pixel rate is 233.3 GPixel/s and its texture rate is 583.2 GTexel/s. These specifications point toward strong performance in traditional rasterized gaming workloads and real-time ray tracing scenarios. The 16 GB of GDDR6 memory on a 256-bit bus provides 624.1 GB/s of bandwidth, which supports high-resolution textures and demanding game scenes.

The Intel Arc Pro B65, by contrast, has 2560 shading units, 160 TMUs, and 80 ROPs. It includes 20 ray tracing cores. Its FP32 compute is 12.29 TFLOPS, while its FP16 compute is 24.58 TFLOPS with a 2:1 ratio. The pixel rate is 192.0 GPixel/s and the texture rate is 384.0 GTexel/s. The Intel card carries 32 GB of GDDR6 memory on a 256-bit bus, yielding 608.0 GB/s of bandwidth. The doubled FP16 throughput relative to FP32 suggests the Arc Pro B65 is oriented toward workloads that leverage packed math, such as certain compute or AI-adjacent tasks, though the card has no dedicated tensor cores.

In terms of memory capacity, the Arc Pro B65 holds a clear advantage with 32 GB compared to the RX 7800 XT’s 16 GB. This doubled memory capacity makes the Intel card more suitable for large datasets, high-resolution compute workloads, or multi-application professional environments where memory footprint is the limiting factor. The RX 7800 XT has higher raw bandwidth at 624.1 GB/s versus 608.0 GB/s, but the difference is small at roughly 2.6%.

The RX 7800 XT has a power draw of 263 W and requires two 8-pin power connectors, with a suggested power supply of 600 W. The Arc Pro B65 draws 200 W and uses a single 8-pin connector, with a suggested power supply of 550 W. The Intel card is more power-efficient in terms of its thermal design power, which could make it preferable in compact workstation builds or environments with power constraints.

The Verdict

Based strictly on recorded data, the AMD Radeon RX 7800 XT is the only card with measured benchmark results. Its average benchmark score of 11627 places it in a competitive tier with the NVIDIA GeForce GTX 1660, AMD Radeon Pro 5500M, NVIDIA Tesla K20c, and AMD Radeon RX 6500 XT, all within a range of about 2% in aggregate scores. The RX 7800 XT delivers 37.32 TFLOPS of FP32 compute, which is roughly three times the FP32 throughput of the Arc Pro B65 at 12.29 TFLOPS. For pure rasterized rendering performance, the RX 7800 XT’s higher shading unit count, texture rate, and pixel rate indicate it should outperform the Intel card in most gaming and graphics workloads.

The Intel Arc Pro B65 offers 32 GB of memory versus the RX 7800 XT’s 16 GB, which is a decisive factor for memory-bound professional workloads. Its lower power draw of 200 W compared to 263 W also makes it a more efficient choice for sustained compute tasks. The Arc Pro B65 supports PCIe 5.0 x16, while the RX 7800 XT uses PCIe 4.0 x16, giving the Intel card a newer bus interface for potential bandwidth advantages in data transfer scenarios.

The RX 7800 XT has a launch MSRP of 499 USD. The Arc Pro B65 has no recorded launch price in the database.

For users prioritizing raw graphics compute, gaming performance, or ray tracing, the RX 7800 XT has the specification advantage and the measured benchmark scores to back it up. For users needing large memory capacity, lower power consumption, or professional workstation features, the Arc Pro B65 presents a compelling specification profile, though its actual performance remains unmeasured in the database.
