AMD Radeon RX 7700 vs Intel Arc Pro B390 Comparison

Head-to-Head Benchmarks

The recorded data contains no shared benchmark entries for the AMD Radeon RX 7700 and the Intel Arc Pro B390. The head-to-head comparison table is empty, and the win counters show zero for both products. This absence of overlapping measurements means a direct score-by-score comparison is not possible from the database. Instead, the analysis must rely on the separate benchmark results for the AMD Radeon RX 7700 and the architectural specifications of the Intel Arc Pro B390.

The AMD Radeon RX 7700 has a full benchmark profile. Its 3DMark Steel Nomad DX12 score is 2865 points. In Geekbench OpenCL, the card records 106028 points. Passmark results show 20974 in G3D, 10963 in GPU Compute, 1206 in G2D, and legacy DirectX scores of 261 for DX9, 186 for DX11, 96 for DX12, and 92 for DX10. The average benchmark score across these tests is 15852 points, placing the card at the 58th percentile of all GPUs in the database.

The nearest rivals in the database provide context for the AMD part. The AMD Radeon R9 370X sits at an average score of 15862, which is 0.1% higher than the RX 7700. The AMD Radeon RX 9060 averages 16014 points, 1% higher. The NVIDIA GeForce RTX 3060 Ti averages 16129 points, 1.7% higher. The AMD Radeon Pro W5500 averages 15679 points, which is 1.1% lower than the RX 7700. These deltas indicate that the RX 7700 sits in a tightly packed performance cluster, with all four rivals within roughly 2% of its average score.

The Intel Arc Pro B390 lists no benchmark entries. Its average benchmark score is recorded as 0, and the nearest rivals array is empty. The percentile field shows 50, but without actual scores, the database cannot position this product against any measured competitor. The practical conclusion from the head-to-head section is that quantitative comparison is unavailable; the Arc Pro B390 must be assessed through its specifications and architectural details alone.

Architecture Differences

The two processors come from different manufacturers and use fundamentally different designs. The AMD Radeon RX 7700 is built on the RDNA 3.0 architecture, uses the Navi 32 chip, and belongs to the Radeon RX 7000 series with the codename Wheat Nas. It is fabricated by TSMC on a 5 nm process, with 28,100 million transistors on a 346 mm² die. The transistor density is 81.2 million per mm².

The Intel Arc Pro B390 uses the Xe3-LPG architecture, is built on the Panther Lake chip, and belongs to the Arc Graphics-WM generation. It is fabricated by Intel on a 3 nm process. The transistor count, die size, and transistor density are all listed as unknown in the database, so no direct manufacturing comparison is possible beyond the process node difference. The RX 7700 uses a larger, denser discrete GPU package, while the Arc Pro B390 is an integrated graphics processor with no separate memory interface.

Memory configuration differs sharply. The RX 7700 has 16 GB of GDDR6 memory on a 256 bit bus, delivering 624.1 GB/s of bandwidth. The memory clock is 2438 MHz, which translates to 19.5 Gbps effective. The Arc Pro B390 uses system shared memory, with the type, bus width, and bandwidth all listed as system dependent. This makes the Intel part entirely reliant on the host system's memory subsystem, whereas the AMD card has dedicated VRAM with a fixed bandwidth figure.

The compute resources also diverge. The RX 7700 has 2560 shading units, 160 texture mapping units, 96 render output units, and 40 ray tracing cores. The Arc Pro B390 has 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. The AMD card has more than double the shading units, more than three times the TMUs, and four times the ROPs.

Clock behavior is another distinction. The RX 7700 has a base clock of 1900 MHz, a game clock of 2041 MHz, and a boost clock of 2459 MHz. The Arc Pro B390 has a base clock of 300 MHz and a boost clock of 2500 MHz. Although the boost clocks are similar, the AMD card sustains a much higher base frequency; the Intel part idles at a very low base and relies on boost behavior, consistent with an integrated part managing power.

Power and physical design differ as well. The RX 7700 has a TDP of 200 W, is dual-slot, uses two 8-pin power connectors, and requires a 550 W suggested PSU. It is a discrete card measuring 267 mm in length, 135 mm in height, and 50 mm in width. The Arc Pro B390 has a TDP of 80 W, is listed as an IGP with no power connectors, no suggested PSU, and no dimensions. Its display outputs are listed as portable device dependent, while the RX 7700 offers 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The FP32 throughput is 25.18 TFLOPS for the RX 7700 with FP16 at a 1:1 ratio, also 25.18 TFLOPS. The Arc Pro B390 delivers 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16 at a 2:1 ratio. Pixel rate for the RX 7700 is 236.1 GPixel/s and texture rate is 393.4 GTexel/s; the Arc Pro B390 manages 60.00 GPixel/s and 120.0 GTexel/s.

The Verdict

The data supports a clear split in use cases. The AMD Radeon RX 7700 is a fully measured discrete GPU with dedicated 16 GB GDDR6 memory, 624.1 GB/s bandwidth, and a 200 W power envelope. Its benchmark scores place it at the 58th percentile of all GPUs, with an average score of 15852 and nearest rivals within 1.7% in either direction. The Arc Pro B390 has no benchmark scores in the database, which makes direct performance claims impossible. Its 80 W TDP, integrated nature, and system shared memory point to a low-power embedded or mobile role, not a desktop discrete card.

The RX 7700 wins on every measured compute metric: shading units, TMUs, ROPs, ray tracing cores, FP32 throughput, pixel rate, texture rate, and memory bandwidth. The Arc Pro B390 has a smaller process node at 3 nm versus 5 nm, a higher boost clock at 2500 MHz versus 2459 MHz, and a much lower TDP at 80 W versus 200 W. Those are the only categories where the Intel part leads in the recorded data.

For a desktop user seeking a dedicated graphics card with verified performance, the RX 7700 is the only option with benchmark evidence. For an integrated or portable device scenario where power draw is minimal and memory is shared with the system, the Arc Pro B390 fits that profile. The data does not support a performance comparison between them because the Intel part lacks any recorded scores.

Where Each One Wins

The AMD Radeon RX 7700 wins in every measured performance category. Its 3DMark Steel Nomad DX12 score of 2865 and Geekbench OpenCL score of 106028 provide direct evidence of 3D and compute capability. The Passmark G3D score of 20974 and GPU Compute score of 10963 reinforce this. The card's dedicated 16 GB GDDR6 memory with 624.1 GB/s bandwidth gives it a fixed memory pipeline that does not depend on host system resources. The 200 W TDP and dual-slot design indicate a card intended for full-power desktop use, with PCIe 4.0 x16 connectivity and three display outputs including HDMI 2.1a, DisplayPort 2.1, and USB Type-C.

The Intel Arc Pro B390 wins in efficiency and integration. Its 80 W TDP is 120 W lower than the RX 7700, and it requires no power connectors. The 3 nm process node is smaller than the 5 nm node used by the AMD chip. The boost clock of 2500 MHz is slightly higher than the RX 7700's 2459 MHz. The IGP form factor, system shared memory, and portable device dependent display outputs make it suitable for compact or embedded systems where a discrete card cannot fit. The 2:1 FP16 ratio, delivering 15.36 TFLOPS versus 7.680 TFLOPS FP32, suggests a design that can accelerate half-precision workloads relatively well, though the absolute numbers are far below the RX 7700's 25.18 TFLOPS in both FP32 and FP16.

The Arc Pro B390 also wins on release recency in the database, with a release date of 2026-01-26 compared to the RX 7700's 2025-09-17. Both products are listed as active in production. The AMD card has a predecessor in Navi II and a successor in Navi IV; the Intel part lists HD Graphics-WM as its predecessor and no successor.
