AMD Radeon RX 9070 GRE vs Intel Arc Pro B390 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between the AMD Radeon RX 9070 GRE and the Intel Arc Pro B390, though the comparison is limited by the fact that the Intel part has no dedicated benchmark entries in the database. The AMD card delivers an average benchmark score of 57367, while the Intel Arc Pro B390 currently holds an average score of 0, meaning no performance measurements have been recorded for it. This absence of data makes a direct head-to-head comparison impossible in the traditional sense, but the available specifications and the AMD card's standing among its rivals provide a clear picture of relative capability.

The AMD Radeon RX 9070 GRE achieves a percentile rank of 87 among all GPUs, placing it in the upper tier of graphics hardware. Its nearest rivals in the database include the Intel Arc A580 with an average score of 57756, a delta of -0.7 percent relative to the RX 9070 GRE, meaning the AMD card trails that specific Intel discrete GPU by a negligible margin. The AMD Radeon RX 5600 OEM scores 58085, which is 1.2 percent higher than the RX 9070 GRE. The Intel Arc A570M posts 58239, a 1.5 percent advantage, and the AMD Radeon RX 6950 XT reaches 58392, 1.8 percent ahead. These deltas are all within two percent, indicating that the RX 9070 GRE sits in a tightly clustered performance band among these four rivals, none of which are the Intel Arc Pro B390.

In contrast, the Intel Arc Pro B390 has no rival entries and no benchmark scores, so its percentile of 50 is derived from its class position rather than measured results. The AMD card's 57367 average score stands against the Intel part's 0, which reflects the absence of recorded testing rather than a literal performance of zero. The data indicates that the RX 9070 GRE delivers 34.28 TFLOPS of FP32 compute, while the Arc Pro B390 manages 7.680 TFLOPS, a factor of roughly 4.5 times in raw floating-point throughput. Pixel rate follows the same pattern: 267.8 GPixel/s for the AMD card versus 60.00 GPixel/s for the Intel part, a 4.46 times difference. Texture rate shows 535.7 GTexel/s against 120.0 GTexel/s, again a 4.46 times gap. These ratios are consistent across shading units, texture mapping units, and raster operations, suggesting that the AMD card's advantage is structural, not merely a matter of clock speeds.

Where Each One Wins

The AMD Radeon RX 9070 GRE wins in every category where data exists. Its 3072 shading units dwarf the Intel Arc Pro B390's 1536, its 192 TMUs compare to 48, and its 96 ROPs compare to 24. The ray tracing cores number 48 on the AMD side versus 12 on the Intel side, a fourfold difference. Memory capacity is another clear win: the RX 9070 GRE has 12 GB of dedicated GDDR6 memory on a 192-bit bus with 432.0 GB/s of bandwidth, while the Arc Pro B390 relies on system shared memory with system dependent bandwidth, meaning its memory performance cannot be quantified independently.

The Intel Arc Pro B390 does hold advantages in specific areas, though these are not performance wins in the benchmark sense. Its process node is 3 nm compared to the AMD card's 4 nm, and it is built by Intel's own foundry rather than TSMC. Its power envelope is far lower at 80 W TDP versus 220 W, and it requires no power connectors, operating as an integrated graphics processor (IGP) rather than a discrete card. The Arc Pro B390 also has a lower base clock of 300 MHz, though its boost clock of 2500 MHz approaches the AMD card's 2790 MHz boost. The Intel part's FP16 throughput is 15.36 TFLOPS at a 2:1 ratio, which is exactly double its FP32 figure, whereas the AMD card delivers equal FP16 and FP32 at 34.28 TFLOPS each, a 1:1 ratio. This means the AMD card offers higher absolute FP16 performance, but the Intel part's FP16 efficiency relative to its own FP32 is better.

For use cases, the RX 9070 GRE is the clear choice for any workload requiring high throughput, such as gaming or compute tasks that leverage FP32 or FP16 at scale. The Arc Pro B390, with its system shared memory and IGP form factor, appears suited to portable or low-power devices where integrated graphics are the only option, but the data shows no performance advantage in any measurable test.

Architecture Differences

The two GPUs come from different architectural lineages. The AMD Radeon RX 9070 GRE uses the Navi 48 chip based on RDNA 4.0, part of the Navi IV (RX 9000) generation, with a predecessor of Navi III. The Intel Arc Pro B390 uses the Panther Lake chip based on Xe3-LPG, part of the Arc Graphics-WM (Panther Lake) generation, with a predecessor of HD Graphics-WM. Neither has a listed codename or successor in the database.

The process nodes differ: AMD uses 4 nm at TSMC, while Intel uses 3 nm at its own foundry. The AMD chip contains 53,900 million transistors on a 357 mm² die, giving a transistor density of 151.0 million per square millimeter. The Intel chip's transistor count and die size are listed as unknown, so no density figure exists. This disparity in known data limits architectural comparison to features that are documented.

Clock behavior differs significantly. The AMD card has a base clock of 1420 MHz, a game clock of 2220 MHz, and a boost clock of 2790 MHz. The Intel part has a base clock of 300 MHz and a boost clock of 2500 MHz, with no game clock listed. The memory clock also diverges: AMD runs at 2250 MHz with 18 Gbps effective, while Intel's memory clock is system shared. The AMD card's bus interface is PCIe 5.0 x16, whereas the Intel part uses an IGP bus interface, meaning it connects through the processor rather than a dedicated slot.

Feature sets are largely aligned on the API front. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Neither has tensor cores listed in the database, so AI accelerator comparisons cannot be made. The AMD card provides display outputs of 1x HDMI 2.1b and 3x DisplayPort 2.1a, while the Intel part's display outputs are listed as portable device dependent, which indicates that its output configuration varies by the host device rather than being fixed. The AMD card is dual-slot with 2x 8-pin power connectors and a suggested PSU of 550 W; the Intel part is an IGP with no power connectors and no suggested PSU listed.

The Verdict

The data points to a straightforward conclusion: the AMD Radeon RX 9070 GRE is the only one of these two that has recorded performance data, and that data places it in the 87th percentile of all GPUs. Its average benchmark score of 57367 is within 1.8 percent of the AMD Radeon RX 6950 XT, a former flagship, and within 0.7 percent of the Intel Arc A580. The Intel Arc Pro B390 has no benchmark scores, no rivals, and an average score of 0, which prevents any quantitative assessment of its real-world performance.

For users who need a discrete graphics card with dedicated memory and high throughput, the RX 9070 GRE is the clear pick based on the available measurements. It offers 12 GB of GDDR6, 432.0 GB/s of bandwidth, and 34.28 TFLOPS of FP32 compute. The Arc Pro B390, by contrast, is an integrated processor with system shared memory and 7.680 TFLOPS of FP32 compute, which is a fraction of the AMD card's capability. The Intel part's lower power draw of 80 W versus 220 W and its lack of external connectors make it suitable for compact or portable systems, but the database contains no performance evidence to recommend it for compute-heavy tasks.

The launch MSRP of the AMD Radeon RX 9070 GRE is 549 USD, and it was released on 2025-05-07. The Intel Arc Pro B390 has no launch MSRP and was released on 2026-01-26. Both are marked as active in production status.
