AMD Radeon RX 7700S vs Intel Arc Pro B390 Comparison

Head-to-Head Benchmarks

The recorded data shows a stark contrast in benchmark availability between these two mobile graphics processors. The AMD Radeon RX 7700S has three documented performance measurements, while the Intel Arc Pro B390 currently has no recorded benchmark scores in the database. This absence of data for the Intel part means a direct numerical comparison cannot be established through standard test suites.

The AMD Radeon RX 7700S delivers a 3DMark Steel Nomad DX12 score of 2185 points. In Geekbench tests, it produces 62983 points in OpenCL and 36380 points in Vulkan. These three results combine to give the RX 7700S an average benchmark score of 33849, placing it in the 78th percentile when ranked against all GPUs in the database.

Without any recorded scores for the Intel Arc Pro B390, its average benchmark score sits at zero, and its percentile ranking is 50th. The database indicates zero wins for each part in head-to-head comparisons, which reflects the missing Intel measurements rather than any competitive outcome.

The closest rivals for the RX 7700S provide useful context for its performance tier. The AMD Radeon HD 7950 averages 33951 points, which puts it 0.3% ahead of the RX 7700S. The AMD Radeon RX 480 scores 33997 points, a 0.4% advantage. On the other side, the NVIDIA GeForce GTX 1060 5 GB averages 33694 points, placing it 0.5% behind the RX 7700S. The NVIDIA RTX A5000 averages 33622 points, trailing by 0.7%. These tight margins show the RX 7700S sits in a competitive band where the surrounding GPUs differ by less than one percent in either direction.

The Intel Arc Pro B390 has no nearest rivals listed, as the database contains no performance data to generate comparisons.

Architecture Differences

The AMD Radeon RX 7700S belongs to the Radeon RX 7000 series and uses the Navi 33 chip built on RDNA 3.0 architecture. Its codename is Hotpink Bonefish, and it comes from the Navi Mobile (RX 7000M) generation. The chip is fabricated on a 6 nm process at TSMC, containing 13,300 million transistors on a 204 mm² die. The transistor density calculates to 65.2M per mm².

The Intel Arc Pro B390 uses the Panther Lake chip built on Xe3-LPG architecture. It comes from the Arc Graphics-WM (Panther Lake) generation. Intel fabricates this chip on a 3 nm process at its own foundry. The transistor count and die size are listed as unknown, so no density figure exists for comparison.

Clock behavior differs substantially. The RX 7700S has a base clock of 1500 MHz, a boost clock of 2500 MHz, and a game clock of 2200 MHz. Its memory clock runs at 2250 MHz with 18 Gbps effective speed. The Arc Pro B390 has a much lower base clock of 300 MHz but reaches the same 2500 MHz boost clock. It has no game clock listed, and its memory clock is marked as system shared.

The memory configurations could not be more different. The RX 7700S uses 8 GB of dedicated GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The Arc Pro B390 uses system shared memory for size, type, bus width, and bandwidth, with bandwidth described as system dependent. This means the Intel part relies entirely on the host system's memory subsystem rather than carrying its own VRAM.

Compute resources show a clear hierarchy. The RX 7700S has 2048 shading units, 128 texture mapping units, 64 render output units, and 32 ray tracing cores. The Arc Pro B390 has 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. Neither part lists tensor cores.

Pixel and texture throughput reflect these resource differences. The RX 7700S achieves 160.0 GPixel/s and 320.0 GTexel/s. The Arc Pro B390 delivers 60.00 GPixel/s and 120.0 GTexel/s. Floating point performance follows the same pattern, with the RX 7700S producing 20.48 TFLOPS in FP32 and 40.96 TFLOPS in FP16 (2:1 ratio), while the Arc Pro B390 produces 7.680 TFLOPS in FP32 and 15.36 TFLOPS in FP16 (2:1 ratio).

Power specifications also differ. The RX 7700S carries a 100 W TDP, while the Arc Pro B390 has an 80 W TDP. Both are integrated graphics processors with no power connectors and portable device dependent display outputs. The RX 7700S uses a PCIe 4.0 x16 bus interface, while the Arc Pro B390 uses an IGP bus interface.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 7700S was released on January 3, 2023, and succeeded Polaris Mobile. The Arc Pro B390 was released on January 26, 2026, and succeeded HD Graphics-WM. Both remain in active production.

Where Each One Wins

The AMD Radeon RX 7700S wins in every category where measurable data exists. Its dedicated 8 GB GDDR6 memory with 288.0 GB/s bandwidth provides a substantial advantage over the Arc Pro B390's system shared memory, whose bandwidth is dependent on the host platform. The RX 7700S also leads in raw compute throughput, delivering 20.48 TFLOPS FP32 versus 7.680 TFLOPS for the Intel part, a 2.67x difference. Texture rate favors AMD at 320.0 GTexel/s versus 120.0 GTexel/s, and pixel rate favors AMD at 160.0 GPixel/s versus 60.00 GPixel/s.

The RX 7700S also holds the edge in ray tracing hardware with 32 RT cores versus 12 on the Arc Pro B390. Its 2048 shading units outnumber Intel's 1536, and its 128 TMUs and 64 ROPs dwarf Intel's 48 TMUs and 24 ROPs. The AMD part has a higher base clock at 1500 MHz versus 300 MHz, though both share a 2500 MHz boost.

The Intel Arc Pro B390 wins in power efficiency based on the listed specifications. It draws 80 W compared to the RX 7700S's 100 W, a 20 W reduction. The Intel part also uses a more advanced 3 nm process node from Intel's own foundry, whereas AMD uses a 6 nm process from TSMC. The Arc Pro B390 was released later, on January 26, 2026, versus January 3, 2023 for the RX 7700S, which means it belongs to a newer generation.

The Arc Pro B390's system shared memory model can be an advantage in unified memory architectures where the CPU and GPU share the same pool, eliminating the need for data copying across a bus. However, the database records no benchmark scores to quantify this potential benefit. The RX 7700S, by contrast, has three recorded benchmarks that place it in the 78th percentile of all GPUs.

The Verdict

The data clearly favors the AMD Radeon RX 7700S for any user seeking documented performance. It has three benchmark scores across DX12, OpenCL, and Vulkan workloads, placing it in the 78th percentile of all GPUs. Its dedicated 8 GB GDDR6 memory with 288.0 GB/s bandwidth provides predictable performance independent of the host system's memory configuration. Its compute resources, including 2048 shading units, 128 TMUs, 64 ROPs, and 32 RT cores, deliver 20.48 TFLOPS FP32 throughput.

The Intel Arc Pro B390 offers no recorded benchmarks, making its real-world performance unverifiable from the database. Its specifications show a smaller compute footprint with 1536 shading units, 48 TMUs, 24 ROPs, and 12 RT cores, producing 7.680 TFLOPS FP32. Its system shared memory approach ties performance to the host platform, which may vary widely between implementations. Its 80 W TDP and 3 nm process suggest efficiency advantages, but no measurements confirm how those translate into actual results.

Users who require verified performance data should select the AMD Radeon RX 7700S. The database contains concrete evidence of its capabilities across multiple test suites, and its percentile ranking demonstrates it competes within a tight band of established GPUs. Users considering the Intel Arc Pro B390 must accept that no benchmark information exists to validate its performance claims. Its newer release date and lower power draw make it an interesting design on paper, but the absence of recorded data leaves its standing unresolved.
