AMD Radeon RX 7600M XT vs Intel Arc B390 Comparison

Where Each One Wins

The recorded benchmark data splits cleanly between these two mobile graphics parts. The AMD Radeon RX 7600M XT wins the only direct head-to-head measurement available, the 3DMark Steel Nomad DX12 test, by a margin of 38.2%. That single result places the AMD part at the 52nd percentile among all GPUs in the database, while the Intel Arc B390 sits at the 9th percentile. The gap in average benchmark scores is substantial: the RX 7600M XT averages 12,710 points across its full benchmark suite, while the Arc B390 averages 1,482 points from its single recorded test.

The AMD card also shows a much broader performance profile. It has ten recorded benchmarks covering DirectX 9, 10, 11, and 12, OpenCL, Vulkan, compute workloads, and 2D graphics. The Arc B390 has only one recorded test result, which limits direct comparison but does not change the outcome of the shared test. In that shared test, the AMD card delivers 2,048 points versus 1,482 points for the Intel part, a 566-point difference that translates to the 38.2% delta.

For use-case selection, the RX 7600M XT is the clear choice for any workload that relies on the measured benchmark categories. Its PassMark G3D score of 13,907 indicates strong general 3D rendering performance, and its PassMark GPU compute score of 7,140 shows capable compute throughput. The Arc B390, with its single Steel Nomad result, lacks recorded data for legacy DirectX versions, OpenCL, Vulkan, or compute. The database shows no scenario where the Intel part wins a recorded benchmark against the AMD part. Every measurable category favors the RX 7600M XT based on the data available.

Architecture Differences

The two GPUs come from different manufacturers, process nodes, and architectural families. The AMD Radeon RX 7600M XT uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename Hotpink Bonefish. It belongs to the Navi Mobile generation within the RX 7000M series. The chip is fabricated on a 6 nm process at TSMC, with 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per square millimeter.

The Intel Arc B390 uses the Panther Lake chip with Xe3-LPG architecture, from the Arc Graphics-M (Panther Lake) generation. It is built on a 3 nm process at Intel's own foundry. The database lists transistor count and die size as unknown for the Intel part, and no transistor density figure is recorded. The process node difference is significant: 6 nm versus 3 nm, which typically allows the smaller node to pack more logic into the same area, but the database does not provide transistor counts to confirm that here.

The memory subsystems differ fundamentally. The AMD card has 8 GB of dedicated GDDR6 memory on a 128-bit bus, with a recorded bandwidth of 288.0 GB/s and an effective memory speed of 18 Gbps. The Intel part uses system shared memory, with system shared type, bus width, and bandwidth that is system dependent. This means the Intel GPU does not have its own dedicated video memory; it relies on the host system's RAM, which can create performance variability depending on the laptop's memory configuration.

Compute resources also differ. The AMD card has 2,048 shading units, 128 texture mapping units, 64 raster output units, and 32 ray tracing cores. The Intel part has 1,536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. The AMD card has significantly more of each resource type. The AMD part also lists a higher pixel rate at 158.0 GPixel/s versus 60.00 GPixel/s for Intel, and a higher texture rate at 316.0 GTexel/s versus 120.0 GTexel/s. FP32 throughput is 20.23 TFLOPS for AMD versus 7.680 TFLOPS for Intel. FP16 rates are 40.45 TFLOPS for AMD and 15.36 TFLOPS for Intel, both at a 2:1 ratio.

Clock speeds differ in an interesting way. The AMD card has a base clock of 1280 MHz and a boost clock of 2469 MHz, with a game clock of 2023 MHz. The Intel part has a much lower base clock of 300 MHz but a boost clock of 2500 MHz, slightly higher than the AMD boost. However, the AMD game clock of 2023 MHz is the more relevant sustained gaming figure, and the Intel part has no recorded game clock.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both are listed as integrated graphics packages (IGP) with no power connectors and portable device dependent display outputs. The AMD TDP is 120 W, while the Intel TDP is 80 W. The AMD card uses PCIe 4.0 x16 as its bus interface, while the Intel part uses IGP, meaning it connects through the system's integrated graphics path rather than a discrete PCIe slot.

Head-to-Head Benchmarks

The only direct comparison in the database is the 3DMark Steel Nomad DX12 test. The AMD Radeon RX 7600M XT scores 2,048 points, and the Intel Arc B390 scores 1,482 points. The AMD card wins by 38.2%. This is a substantial margin in a modern DirectX 12 workload, indicating that the AMD card delivers roughly 1.38 times the performance of the Intel part in this specific test.

For context relative to the nearest rivals listed in the database, the AMD card's average benchmark score of 12,710 places it close to the NVIDIA GeForce GTX 670 (12,773 points, 0.5% behind the AMD), the AMD Radeon Pro 455 (12,831 points, 0.9% ahead), and the NVIDIA GeForce GTX 590 (12,830 points, 0.9% ahead). The AMD card also sits just ahead of the NVIDIA Tesla K20Xm (12,625 points, 0.7% behind the AMD). These are all desktop-class GPUs from earlier generations, which makes the RX 7600M XT's position notable for a mobile part.

The Intel Arc B390's nearest rivals are much lower in the performance hierarchy. Its average score of 1,482 points places it near the NVIDIA GeForce GT 520MX (1,463 points, 1.3% behind the Intel), the NVIDIA GeForce 800M (1,460 points, 1.5% behind), the NVIDIA GeForce GT 625 OEM (1,446 points, 2.5% behind), and the NVIDIA GeForce GT 710 (1,443 points, 2.7% behind). These are entry-level GPUs from a much older era, and the Intel part is only slightly ahead of them. The percentile ranking confirms this: the Arc B390 sits at the 9th percentile of all GPUs, meaning roughly 91% of recorded GPUs outperform it.

The AMD card also has a richer individual benchmark profile. Its PassMark G3D score of 13,907 and PassMark GPU compute score of 7,140 are high enough to suggest strong general-purpose and compute performance. The Geekbench OpenCL score of 74,869 and Vulkan score of 27,793 further indicate solid performance across different API families. The PassMark DirectX scores show 175 for DX9, 137 for DX11, 76 for DX10, and 58 for DX12, with a 2D score of 894. These numbers are not directly comparable to the Intel part because the Intel part has no recorded scores in any of these tests, but they establish the AMD card's wide-ranging capability.

The wins tally in the database is 1 for the AMD card and 0 for the Intel part. There is no recorded benchmark where the Arc B390 outperforms the RX 7600M XT.

The Verdict

The data points to a clear recommendation for most use cases. The AMD Radeon RX 7600M XT outperforms the Intel Arc B390 in the only shared benchmark by 38.2%, has a higher average benchmark score (12,710 versus 1,482), sits at a much higher percentile rank (52 versus 9), and offers dedicated 8 GB GDDR6 memory instead of system shared memory. The AMD card also has more shading units, TMUs, ROPs, ray tracing cores, higher pixel rate, higher texture rate, and higher FP32 and FP16 throughput.

The Intel Arc B390 does have advantages in specific areas. It uses a smaller 3 nm process node, which suggests better power efficiency per transistor, and its TDP is 80 W versus 120 W for the AMD card. Its boost clock of 2500 MHz is also slightly higher. However, these advantages do not translate into measured performance wins in the database. The Intel part's base clock of 300 MHz is very low, and its lack of dedicated memory means its bandwidth is system dependent.

For a laptop buyer who needs measured 3D performance, DirectX 12 capability, and compute throughput, the RX 7600M XT is the stronger choice based on the recorded data. The Arc B390 might be suitable for systems where power draw is critical and the workload is very light, but the benchmark results show it performs near the level of decade-old entry-level desktop GPUs like the GeForce GT 710 or GT 520MX. The AMD card, by contrast, performs near the level of the GeForce GTX 670 or GTX 590, which were high-end desktop parts in their time.

The database records one win for AMD and zero for Intel in head-to-head testing. Nothing in the measured data suggests the Intel part can close that gap. The process node advantage is real, but it has not produced a competitive benchmark result in this case.
