Architecture Differences

The AMD Radeon RX 7600 XT is built on the RDNA 3.0 architecture, using the Navi 33 chip with the codename Hotpink Bonefish. It belongs to the Navi III generation (RX 7000 series). The Intel Arc B390 uses the Xe3-LPG architecture, built on the Panther Lake chip, and is part of the Arc Graphics-M (Panther Lake) generation. The manufacturing processes differ significantly. The RX 7600 XT is fabricated on a 6 nm process at TSMC, while the Arc B390 uses a 3 nm process at Intel. The AMD chip contains 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2M per mm². The Intel chip's transistor count and die size are listed as unknown in the database.

The memory configurations are fundamentally different. The RX 7600 XT has 16 GB of dedicated GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The Arc B390 uses System Shared memory, with the type, bus width, and bandwidth all listed as System Shared or System Dependent. This means the Intel part relies on the host system's memory rather than having its own dedicated VRAM.

Core configurations also diverge sharply. The RX 7600 XT has 2048 shading units, 128 texture mapping units, 64 raster output units, and 32 ray tracing cores. The Arc B390 has 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. The AMD card has significantly more of each resource type. Clock speeds show a different pattern. The RX 7600 XT has a base clock of 1980 MHz, a boost clock of 2755 MHz, and a game clock of 2470 MHz. The Arc B390 has a base clock of 300 MHz and a boost clock of 2500 MHz, with no separate game clock listed. The AMD card's base clock is much higher, while the boost clocks are closer, though the AMD part still leads by 255 MHz.

The compute throughput numbers reflect these differences. The RX 7600 XT delivers 22.57 TFLOPS of FP32 performance and 22.57 TFLOPS of FP16 (at a 1:1 ratio). The Arc B390 delivers 7.680 TFLOPS of FP32 and 15.36 TFLOPS of FP16 (at a 2:1 ratio). The AMD solution has nearly three times the FP32 throughput. Pixel and texture rates follow the same pattern. The RX 7600 XT has a pixel rate of 176.3 GPixel/s and a texture rate of 352.6 GTexel/s. The Arc B390 has a pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s.

Power characteristics are very different, which is expected given the form factors. The RX 7600 XT has a TDP of 190 W, uses a dual-slot design, requires a single 8-pin power connector, and a suggested PSU of 450 W. It connects via PCIe 4.0 x8. The Arc B390 has a TDP of 80 W, is an IGP (integrated graphics processor), uses no power connectors, and has no suggested PSU listed. Its bus interface is listed as IGP, meaning it connects directly to the system rather than through a standard expansion slot. Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD card has display outputs of 1x HDMI 2.1a and 3x DisplayPort 2.1, while the Arc B390's outputs are listed as Portable Device Dependent.

Where Each One Wins

The benchmark data shows the AMD Radeon RX 7600 XT winning the only head-to-head test, the 3DMark Steel Nomad DX12 benchmark, by 58.4%. This is the only recorded comparison point, so the win analysis is straightforward. The RX 7600 XT wins the recorded DirectX 12 workload decisively. The Arc B390 has no recorded wins in the head-to-head data.

Looking at the broader benchmark records, the RX 7600 XT has results across ten different tests. These include 3DMark Steel Nomad DX12 (score 2348), Geekbench OpenCL (92426), Geekbench Vulkan (48366), Passmark DirectX 10 (85), Passmark DirectX 11 (167), Passmark DirectX 12 (65), Passmark DirectX 9 (228), Passmark G2D (1030), Passmark G3D (17132), and Passmark GPU Compute (8987). The Arc B390 has only the single 3DMark Steel Nomad result.

The use-case split is therefore heavily skewed toward the AMD part in the recorded data. The RX 7600 XT's higher FP32 throughput (22.57 TFLOPS vs 7.680 TFLOPS) and higher texture rate (352.6 GTexel/s vs 120.0 GTexel/s) would suggest advantages in traditional rasterization workloads. The AMD card's dedicated 16 GB GDDR6 memory with 288.0 GB/s bandwidth provides a clear advantage for large texture datasets, whereas the Arc B390 depends on system memory with bandwidth listed as System Dependent.

The Arc B390's advantages are in power consumption and form factor. Its TDP of 80 W is 110 W lower than the RX 7600 XT's 190 W. It requires no power connectors and uses an IGP form factor, meaning it can be integrated into portable devices. The B390's display outputs are listed as Portable Device Dependent, suggesting its target market is laptops or compact systems where the RX 7600 XT's dual-slot, 204 mm length design would not fit.

The Arc B390's FP16 performance of 15.36 TFLOPS is higher relative to its FP32 performance (2:1 ratio), whereas the RX 7600 XT has a 1:1 ratio. This could indicate a relative strength in workloads that leverage FP16 compute, though no specific benchmark data supports this in the recorded results. The RX 7600 XT still has higher absolute FP16 throughput at 22.57 TFLOPS.

The Verdict

The data indicates a clear performance hierarchy between these two products. The AMD Radeon RX 7600 XT delivers 58.4% higher scores in the 3DMark Steel Nomad DX12 test. Its average benchmark score of 17083 places it at the 60th percentile of all GPUs, while the Intel Arc B390's average score of 1482 places it at the 9th percentile. These metrics show the RX 7600 XT as a mid-range discrete graphics card, while the Arc B390 sits near the bottom of the performance spectrum in the database.

The RX 7600 XT's nearest rivals include the NVIDIA GeForce RTX 3070, with the AMD card trailing by just 0.7% in average score.
