AMD Radeon RX 7600S vs Intel Arc Pro B390 Comparison

Head-to-Head Benchmarks

The recorded data shows a difficult comparison situation: the AMD Radeon RX 7600S has a full set of ten benchmark entries, while the Intel Arc Pro B390 has no recorded benchmark scores at all. The database lists zero measurements for the Intel part, which means there is no direct head-to-head score comparison available. The AMD Radeon RX 7600S produces measurable results in every test category, including 3DMark Steel Nomad DX12 with a score of 1888, Geekbench OpenCL at 68012, and Geekbench Vulkan at 73868. The Intel Arc Pro B390's benchmark array is empty, so its performance can only be assessed through architectural characteristics and the percentile placement assigned by the database.

The AMD Radeon RX 7600S holds an average benchmark score of 16696 across its ten entries, which places it at the 60th percentile of all GPUs tracked. Its nearest rivals in the database provide context for this score. The NVIDIA T400 4 GB has an average score of 16792, which puts the AMD part 0.6% behind that rival. The NVIDIA T400 comes in at 16508, placing the RX 7600S 1.1% ahead. The NVIDIA GeForce RTX 5090 D V2 averages 16504, with the RX 7600S leading by 1.2%. The NVIDIA Tesla M4 sits at 16932, and the RX 7600S trails by 1.4%. These deltas are all within roughly one and a half percentage points, indicating that the RX 7600S clusters tightly with a group of professional and workstation-oriented GPUs rather than dominating them.

The Intel Arc Pro B390, by contrast, carries a 50th percentile placement with an average benchmark score of zero and no nearest rivals listed. The database records no wins for either product in a head-to-head sense, since no matching test results exist for the Intel part. What the data does show is that the RX 7600S has substantial measured output across DirectX 9, 10, 11, and 12 workloads, plus compute and graphics tests. Its Passmark DirectX 9 score is 211, DirectX 10 is 74, DirectX 11 is 140, and DirectX 12 is 65. The Passmark G3D score reaches 15408, G2D reaches 776, and GPU compute scores 6520. These figures establish a baseline for the AMD product, but the Intel product cannot be ranked against them because no equivalent measurements exist.

Where Each One Wins

The AMD Radeon RX 7600S wins in every category where data exists, simply because it is the only one of the two with benchmark results. Its strongest recorded showings are in Geekbench Vulkan at 73868 and Geekbench OpenCL at 68012, which are far above its Passmark scores. The Passmark G3D result of 15408 indicates solid rasterization performance, while the GPU compute score of 6520 shows the architecture handles general-purpose workloads. The DirectX 9 score of 211 is the highest among its Passmark DirectX entries, which suggests older API workloads run relatively well, while DirectX 12 at 65 and DirectX 10 at 74 are lower, possibly reflecting driver optimization or test methodology rather than raw capability.

The Intel Arc Pro B390 has no recorded wins in any benchmark category. Its database profile is defined entirely by specifications and the 50th percentile placement, which is a neutral position indicating average standing among all GPUs. Without test scores, the Intel part cannot claim a win in any measured workload. The data does show that the Intel product targets a different segment: its generation is labeled Arc Graphics-WM (Panther Lake), which is a workstation-mobile hybrid, whereas the AMD part belongs to the Radeon RX 7000 series for mobile gaming laptops. The Intel part's memory is System Shared, meaning it relies on the host system's RAM rather than dedicated VRAM, which typically affects performance in memory-intensive tasks. The AMD part has 8 GB of dedicated GDDR6, giving it a clear structural advantage for graphics workloads that require large local memory pools.

Architecture Differences

The two GPUs come from different manufacturers and use fundamentally different architectures. The AMD Radeon RX 7600S uses the Navi 33 chip with RDNA 3.0 architecture, codenamed Hotpink Bonefish, and belongs to the Navi Mobile (RX 7000M) generation. It 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 Pro B390 uses the Panther Lake chip with Xe3-LPG architecture and belongs to the Arc Graphics-WM (Panther Lake) generation. It is fabricated on a 3 nm process at Intel's own foundry, but the transistor count and die size are listed as unknown in the database.

The compute configurations differ significantly. The AMD chip has 1792 shading units, 112 texture mapping units, and 64 ROPs, along with 28 ray tracing cores. The Intel chip has 1536 shading units, 48 TMUs, and 24 ROPs, with 12 ray tracing cores. In terms of raw throughput, the AMD part delivers 15.77 TFLOPS FP32 and 31.54 TFLOPS FP16 (2:1), while the Intel part delivers 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16 (2:1). That puts the AMD part at roughly double the FP32 compute of the Intel part. Pixel rate also favors AMD: 140.8 GPixel/s versus 60.00 GPixel/s. Texture rate favors AMD as well: 246.4 GTexel/s versus 120.0 GTexel/s.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature parity exists. Neither has tensor cores listed. Both use an IGP slot width, meaning they are integrated into a mobile platform, and both have Portable Device Dependent display outputs. The AMD part uses a PCIe 4.0 x16 bus interface, while the Intel part uses an IGP bus interface, which reflects its system-shared memory design. The Intel part's clock behavior is also distinct: its base clock is 300 MHz with a boost of 2500 MHz, while the AMD part has a base of 1500 MHz, a game clock of 1865 MHz, and a boost of 2200 MHz. The Intel part's lower base clock and higher boost ceiling suggest a more aggressive boost-dependent design, while the AMD part runs at higher sustained clocks.

Specification Differences

Power and memory are the most visible specification differences. The AMD Radeon RX 7600S has a TDP of 75 W, while the Intel Arc Pro B390 has a TDP of 80 W, making the Intel part slightly more power-hungry on paper. Neither requires power connectors, consistent with their IGP form factors. Neither has a suggested PSU listed.

Memory is where the two diverge sharply. The AMD part has 8 GB of GDDR6 on a 128-bit bus, with 256.0 GB/s bandwidth and a memory clock of 2000 MHz (16 Gbps effective). The Intel part has System Shared memory, meaning its size, type, bus width, and bandwidth are all dependent on the host system. The database lists its memory bandwidth as System Dependent, which means no fixed figure can be stated. The Intel part's memory clock is also System Shared.

Clock speeds also differ. The AMD part's base clock is 1500 MHz, game clock is 1865 MHz, and boost is 2200 MHz. The Intel part's base clock is 300 MHz and boost is 2500 MHz, with no game clock listed. The memory clock for the AMD part is 2000 MHz, while the Intel part has no memory clock of its own.

Release dates differ by three years. The AMD part was released on 2023-01-03, while the Intel part is dated 2026-01-26. Both are currently marked as Active in production status. The AMD part's predecessor is Polaris Mobile, and the Intel part's predecessor is HD Graphics-WM. Neither has a successor listed. Neither has a launch MSRP in the database. The AMD part's process node is 6 nm at TSMC, while the Intel part uses 3 nm at Intel. The die size and transistor count for the Intel part are unknown, while the AMD part has a 204 mm² die with 13,300 million transistors.

The Verdict

The data points to the AMD Radeon RX 7600S as the more complete product for measured graphics performance. It has a full set of benchmark scores, an average score of 16696, and a 60th percentile placement. Its nearest rivals, all NVIDIA parts, sit within 1.4% of its average score, which shows it competes directly with that tier of hardware. The Intel Arc Pro B390 has no benchmark results, no average score, and no nearest rivals, so its performance cannot be verified from the database.

For users who need dedicated graphics memory, the AMD part is the clear choice. Its 8 GB of GDDR6 with 256.0 GB/s bandwidth provides a fixed, predictable memory subsystem. The Intel part's System Shared memory means performance depends entirely on the host system's RAM configuration, which introduces variability. The AMD part also delivers higher compute throughput, with 15.77 TFLOPS FP32 versus 7.680 TFLOPS, and higher pixel and texture rates.

The Intel part does have advantages in the specifications that are recorded. Its 3 nm process node is smaller than the AMD part's 6 nm node, and its boost clock is 2500 MHz versus 2200 MHz. Its TDP is slightly higher at 80 W versus 75 W, but that does not translate into any measured performance advantage. The Intel part's 50th percentile placement is below the AMD part's 60th percentile, which reinforces the ordering.

The verdict from the database is straightforward: the AMD Radeon RX 7600S is the only one of the two with recorded performance data, and that data places it in the upper half of all GPUs. The Intel Arc Pro B390 is a newer product with a smaller process node and higher boost clock, but without benchmark results, its actual performance cannot be quantified. Buyers who want verified performance should look at the AMD part. Buyers who value the Intel part's 3 nm process and system-shared memory design may consider it, but the database provides no evidence of its performance level.
