AMD Radeon RX 7800 XT vs Intel Arc Pro B390 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark comparisons between the AMD Radeon RX 7800 XT and the Intel Arc Pro B390. The head-to-head array is empty, and the win count for both parts is zero. This absence of direct measurements means any comparative analysis must rely on the standalone benchmark scores recorded for the AMD part and the architectural specifications of the Intel part.

The AMD Radeon RX 7800 XT has a substantial set of recorded measurements. In 3DMark Steel Nomad DX12, it scores 4157 points. Geekbench OpenCL shows 18290 points, while Geekbench Vulkan reaches 54228 points. PassMark G3D reports 24176 points, and PassMark GPU Compute adds 13473 points. The average benchmark score across all recorded tests is 11627 points, placing it at the 51st percentile among all GPUs in the database.

The Intel Arc Pro B390 has no recorded benchmark scores at all. Its average benchmark score is 0, and its percentile is 50, which reflects only the default position for an unmeasured entry. The database contains no performance numbers for this part, so direct numerical comparisons are impossible. The analysis must instead rely on the architectural and specification differences to infer relative positioning.

Because the AMD part has measurable scores and the Intel part does not, the data cannot confirm any performance lead in either direction. The only quantitative statements available concern the AMD card's absolute scores and its position relative to its nearest recorded rivals. The Intel card's performance remains entirely unquantified in this database.

The Verdict

The data shows a clear asymmetry in measurement coverage. The AMD Radeon RX 7800 XT has a full set of benchmark results, while the Intel Arc Pro B390 has none. For any user relying strictly on recorded measurements, the AMD part is the only one with evidence of performance capability.

The AMD card's 51st percentile ranking and 11627 average score place it in the middle of the database distribution. Its nearest rivals include the NVIDIA GeForce GTX 1660 with an average score of 11680, a 0.5% difference, and the AMD Radeon Pro 5500M at 11528, a 0.9% difference. The AMD Radeon RX 6500 XT scores 11842, putting the RX 7800 XT 1.8% behind that part. The NVIDIA Tesla K20c scores 11479, with the RX 7800 XT ahead by 1.3%.

The Intel Arc Pro B390 cannot be placed in any ranking because no scores exist. Its percentile of 50 is a placeholder, not a measurement. Any verdict must acknowledge that the Intel part is unmeasured and therefore unranked.

The recorded data indicates that the AMD Radeon RX 7800 XT is a discrete, actively sold graphics card with a launch MSRP of 499 USD. The Intel Arc Pro B390 is an integrated graphics processor, part of the Panther Lake generation, with no launch MSRP recorded. These are different product categories, and the database does not provide evidence to compare their real-world performance.

Where Each One Wins

The AMD Radeon RX 7800 XT wins on every recorded performance metric because it is the only part with benchmark scores. Its 51st percentile ranking and 11627 average score give it a measurable position in the database. The Intel Arc Pro B390 has no scores, so it cannot claim any benchmark win.

The AMD card wins on compute throughput. Its FP32 performance of 37.32 TFLOPS is far above the Intel part's 7.680 TFLOPS. Its texture rate of 583.2 GTexel/s and pixel rate of 233.3 GPixel/s dwarf the Intel part's 120.0 GTexel/s and 60.00 GPixel/s. The AMD card also has more shading units, TMUs, ROPs, and ray tracing cores.

The Intel Arc Pro B390 wins on power efficiency in terms of TDP. Its 80 W TDP is much lower than the AMD card's 263 W. It also has a higher boost clock at 2500 MHz compared to the AMD card's 2430 MHz, though the AMD card has a much higher base clock at 1295 MHz versus 300 MHz.

The Intel part uses a smaller 3 nm process node, while the AMD card uses a 5 nm node. The Intel part is an integrated processor with no power connectors and system shared memory, which suits portable devices. The AMD card is a discrete dual-slot card requiring 2x 8-pin connectors and a 600 W PSU.

The AMD card wins on dedicated memory bandwidth with 624.1 GB/s, while the Intel part has no dedicated memory of its own. The AMD card also offers a full set of display outputs including HDMI 2.1a and DisplayPort 2.1, while the Intel part's outputs depend on the portable device.

For users who need a discrete graphics solution with measurable performance, the AMD Radeon RX 7800 XT is the only part with recorded data. For integrated graphics in a portable device with low power draw, the Intel Arc Pro B390 has the architectural profile of an IGP, but no benchmark evidence exists to support any performance claim.
