Where Each One Wins

The recorded data shows a clear split in capabilities. The AMD Radeon RX 7600S wins the only direct benchmark comparison, the 3DMark Steel Nomad DX12 test, with a score of 1888 versus 1482 for the Intel Arc B390, a 27.4% advantage. This single data point establishes the AMD part as the stronger option for DX12 gaming workloads.

The AMD Radeon RX 7600S also demonstrates broad strength across multiple benchmark suites. Its PassMark G3D score of 15408, Geekbench OpenCL score of 68012, and Geekbench Vulkan score of 73868 show solid compute and graphics performance. The Intel Arc B390 has no recorded results for these tests, so the database contains no evidence of it competing in those workloads.

Where the Intel Arc B390 could claim an edge is in power efficiency relative to its performance tier. With a TDP of 80 W, it draws only 5 W more than the AMD part while delivering substantially lower performance. For lightweight tasks, the Intel GPU's lower absolute performance might align with lower system requirements, but the data does not include any benchmark where the Intel part wins.

The 9th percentile ranking for the Intel Arc B390 indicates it performs near the bottom of the database. In contrast, the AMD Radeon RX 7600S at the 60th percentile places it firmly in the mid-range of all recorded GPUs.

Architecture Differences

The AMD Radeon RX 7600S uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed Hotpink Bonefish. It belongs to the Navi Mobile (RX 7000M) generation and is manufactured by TSMC on a 6 nm process. The chip contains 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2M per mm².

The Intel Arc B390 uses the Panther Lake chip built on Xe3-LPG architecture, belonging to the Arc Graphics-M (Panther Lake) generation. It is manufactured by Intel on a 3 nm process. The database lists transistor count, die size, and transistor density as unknown for this part.

The AMD GPU features 1792 shading units, 112 texture mapping units, and 64 raster operation pipelines. It includes 28 ray tracing cores. The Intel GPU has 1536 shading units, 48 TMUs, and 24 ROPs, with 12 ray tracing cores. The AMD part has more units across every category, which aligns with its higher compute throughput.

Both GPUs are classified as IGP (integrated graphics processor) with portable device dependent display outputs. Neither uses power connectors, and both have active production status.

Specification Differences

The clock speeds differ substantially. The AMD Radeon RX 7600S has a base clock of 1500 MHz, a boost clock of 2200 MHz, and a game clock of 1865 MHz. The Intel Arc B390 has a base clock of 300 MHz and a boost clock of 2500 MHz, with no game clock listed. The Intel part boosts 300 MHz higher but has a much lower base clock.

Memory configurations are fundamentally different. The AMD part uses 8 GB of GDDR6 memory on a 128-bit bus with 256.0 GB/s bandwidth. The Intel part uses system-shared memory with system-dependent bandwidth. The memory clock for AMD is 2000 MHz (16 Gbps effective), while Intel's memory clock is listed as system shared.

The compute output shows a large gap. The AMD Radeon RX 7600S delivers 15.77 TFLOPS FP32 and 31.54 TFLOPS FP16 (2:1). The Intel Arc B390 delivers 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16 (2:1). The AMD part has roughly double the raw compute throughput.

Pixel and texture rates follow the same pattern. AMD achieves 140.8 GPixel/s and 246.4 GTexel/s, while Intel achieves 60.00 GPixel/s and 120.0 GTexel/s.

The bus interface differs: AMD uses PCIe 4.0 x16, while Intel uses IGP. The TDP differs by 5 W, with AMD at 75 W and Intel at 80 W.

Release dates are separated by roughly three years. The AMD Radeon RX 7600S launched on January 3, 2023, while the Intel Arc B390 launched on January 26, 2026.

Head-to-Head Benchmarks

The database contains one head-to-head benchmark result between these two GPUs. In the 3DMark Steel Nomad DX12 test, the AMD Radeon RX 7600S scores 1888 points, and the Intel Arc B390 scores 1482 points. The AMD part wins with a delta of 27.4%.

This 27.4% delta is substantial. It places the AMD GPU in a different performance class entirely. To contextualize, the AMD part's closest rival, the NVIDIA T400 4 GB, scores within 0.6% of the AMD average. The Intel Arc B390's closest rival, the NVIDIA GeForce GT 520MX, scores within 1.3%. These rival clusters are far apart, confirming the two GPUs do not compete in the same tier.

The AMD Radeon RX 7600S also has additional benchmark results beyond the head-to-head test. Its PassMark G3D score of 15408 and PassMark GPU Compute score of 6520 demonstrate strong general-purpose performance. The Geekbench OpenCL score of 68012 and Vulkan score of 73868 further indicate capable compute workloads. The Intel Arc B390 lacks recorded results for these tests, so no comparison is possible.

The AMD part shows a balanced profile across DirectX versions in PassMark testing: DirectX 9 scores 211, DirectX 10 scores 74, DirectX 11 scores 140, and DirectX 12 scores 65. The PassMark G2D score of 776 indicates reasonable 2D performance.

The Verdict

The data points to a clear performance hierarchy. The AMD Radeon RX 7600S delivers 27.4% higher performance in the sole shared benchmark, the 3DMark Steel Nomad DX12 test. Its average benchmark score of 16696 is more than 11 times higher than the Intel Arc B390's average of 1482.

The percentile rankings reinforce this gap. The AMD part sits at the 60th percentile of all GPUs, placing it in the middle of the performance distribution. The Intel Arc B390 sits at the 9th percentile, near the bottom. Users seeking playable DX12 performance should look to the AMD Radeon RX 7600S based on the recorded data.

The Intel Arc B390 does have a higher boost clock (2500 MHz versus 2200 MHz) and a smaller process node (3 nm versus 6 nm), but these advantages do not translate into benchmark wins. The AMD part compensates with more shading units, TMUs, ROPs, ray tracing cores, and double the FP32 throughput.

For compute-heavy workloads, the AMD Radeon RX 7600S has recorded evidence of capability with its Geekbench and PassMark compute scores. The Intel Arc B390 has no such recorded results.

The 5 W TDP difference is minor: Intel draws 80 W versus AMD's 75 W. Both are IGP parts with no power connectors, suited for portable devices.

The choice depends on performance requirements. The AMD Radeon RX 7600S is the stronger GPU in every measured category. The Intel Arc B390, with its 9th percentile ranking and single benchmark result, appears positioned for basic graphics tasks rather than demanding applications. The database records one win for AMD and zero for Intel.
