AMD Radeon RX 7800 XT vs Intel Arc Pro B70 Comparison

Where Each One Wins

The recorded data splits these two cards into clearly different use cases, though the benchmark evidence is one-sided. The AMD Radeon RX 7800 XT has a full set of measured scores across DirectX 9, 10, 11, 12, OpenCL, Vulkan, and compute workloads. The Intel Arc Pro B70 has no recorded benchmark results in the database, so its wins cannot be demonstrated from measurements. That does not mean the Intel card lacks capability; it means the current data does not support any quantitative claim of victory for it.

What the data does show is that the RX 7800 XT wins in every test where a score exists. Its average benchmark score is 11,627 across ten tests, while the Arc Pro B70 shows an average of 0 due to the empty benchmark array. The RX 7800 XT also holds the 51st percentile among all GPUs, versus the 50th percentile for the Arc Pro B70. That one percentage point difference is thin, but it is the only percentile comparison available.

For a builder choosing between these two, the practical split is: the RX 7800 XT is the card with proven performance data, while the Arc Pro B70 is a newer, larger-memory option whose performance is unmeasured in this database. If the workload is gaming or general compute where you need verified numbers, the RX 7800 XT is the only card with evidence. If the workload demands 32 GB of VRAM, the Arc Pro B70 has a capacity advantage that the RX 7800 XT cannot match, but you would be buying without benchmark confirmation.

Architecture Differences

Both cards use a 5 nm process at TSMC, which is a rare point of agreement. The RX 7800 XT uses the Navi 32 chip with RDNA 3.0 architecture, codename Wheat Nas, part of the Navi III (RX 7000) generation. The Arc Pro B70 uses the BMG-G31 chip with Xe2-HPG architecture, part of the Battlemage (Pro Series) generation, and has no codename listed.

Transistor counts differ sharply. The RX 7800 XT packs 28,100 million transistors on a 346 mm² die, giving a density of 81.2 million transistors per square millimeter. The Arc Pro B70 has an unknown transistor count but a larger die at 368 mm², with no density figure recorded. The die size difference of 22 mm² is modest, but the Intel card achieves it with an unknown transistor budget.

The memory subsystems are similar in bus width but not in capacity. Both use GDDR6 on a 256-bit bus. The RX 7800 XT has 16 GB with 624.1 GB/s bandwidth, while the Arc Pro B70 doubles capacity to 32 GB but sees bandwidth drop slightly to 608.0 GB/s. Clock speeds favor the Intel card: its base is 2280 MHz and boost is 2800 MHz, versus 1295 MHz base and 2430 MHz boost for AMD. The AMD card also lists a game clock of 2124 MHz, which Intel does not report.

Shader and fixed-function hardware go in different directions. The RX 7800 XT has 3840 shading units, 240 TMUs, 96 ROPs, and 60 ray tracing cores. The Arc Pro B70 has more shading units at 4096, more TMUs at 256, more ROPs at 128, but fewer ray tracing cores at 32. Pixel rate favors Intel at 358.4 GPixel/s versus 233.3 GPixel/s, and texture rate favors Intel at 716.8 GTexel/s versus 583.2 GTexel/s. Floating-point performance splits by precision: the RX 7800 XT delivers 37.32 TFLOPS for both FP32 and FP16 (1:1 ratio), while the Arc Pro B70 delivers 22.94 TFLOPS FP32 but 45.88 TFLOPS FP16 (2:1 ratio). That makes the Intel card roughly twice as strong in half-precision relative to its single-precision rate.

Power and connectivity differ as well. The RX 7800 XT has a 263 W TDP, requires a 600 W suggested PSU, and uses two 8-pin power connectors. The Arc Pro B70 runs at 230 W TDP, needs a 550 W PSU, and uses a single 8-pin connector. Both are dual-slot cards, but the AMD card is 50 mm wide versus 39 mm for Intel. Both use PCIe, though the AMD card is PCIe 4.0 x16 and the Intel card is PCIe 5.0 x16. Display outputs are identical: 1x HDMI 2.1a and 3x DisplayPort 2.1.

API support matches exactly: both list DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 7800 XT is marked as Active in production and has a release date of September 5, 2023, with a predecessor (Navi II) and successor (Navi IV) noted. The Arc Pro B70 has no production status, no predecessor or successor, and a release date of March 25, 2026.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two cards, so a direct test-by-test comparison is not possible from recorded data. The only comparable metric is the average benchmark score, where the RX 7800 XT sits at 11,627 and the Arc Pro B70 at 0. That gap is not informative because the Intel card lacks any individual scores.

For the RX 7800 XT alone, the individual results show a wide spread depending on the workload. The strongest score is Geekbench Vulkan at 54,228, followed by Passmark G3D at 24,176. Geekbench OpenCL comes in at 18,290, and Passmark GPU Compute at 13,473. The Passmark DirectX tests are much lower: DirectX 9 at 304, DirectX 11 at 249, DirectX 10 at 121, and DirectX 12 at 93. Passmark G2D scores 1,177, and 3DMark Steel Nomad DX12 scores 4,157.

Relative to its nearest rivals, the RX 7800 XT sits in a tight cluster. It trails the NVIDIA GeForce GTX 1660 by 0.5%, where the GTX 1660 has an average score of 11,680. It leads the AMD Radeon Pro 5500M by 0.9% (11,528), the NVIDIA Tesla K20c by 1.3% (11,479), and trails the AMD Radeon RX 6500 XT by 1.8% (11,842). None of these deltas exceed two percent, which means the RX 7800 XT is essentially performance-neutral against that group of older or lower-tier cards. The Arc Pro B70 has no rivals listed, so no comparative statements can be made about it.

The practical takeaway from the numbers is that the RX 7800 XT delivers its best results in Vulkan and general 3D workloads, while its DirectX 12 result in 3DMark Steel Nomad is a mid-range showing. The Passmark DirectX scores are low across the board, which suggests those specific legacy tests do not favor this architecture. Without any scores for the Arc Pro B70, there is no way to say which card wins any particular workload.

The Verdict

The data points to a clear choice for most buyers: the AMD Radeon RX 7800 XT is the only card here with any recorded performance evidence. It has ten benchmark scores, an average of 11,627, and a 51st percentile ranking. The Intel Arc Pro B70 has no scores, no average, and no rival comparisons. If you need a card that is proven in the database, the RX 7800 XT is the pick.

The Arc Pro B70 justifies consideration only through its specifications. It offers 32 GB of memory, which is double the RX 7800 XT's 16 GB, and it has a higher pixel rate (358.4 GPixel/s versus 233.3 GPixel/s), higher texture rate (716.8 GTexel/s versus 583.2 GTexel/s), and higher FP16 throughput (45.88 TFLOPS versus 37.32 TFLOPS). It also runs on PCIe 5.0 x16, draws less power (230 W versus 263 W), and uses a single 8-pin connector. Those are real advantages on paper, but they carry no benchmark confirmation.

For gaming and general single-precision compute, the RX 7800 XT delivers 37.32 TFLOPS FP32 and a full set of measured results. For workloads that need 32 GB of VRAM or heavy half-precision math, the Arc Pro B70 has the hardware specification advantage, but the absence of recorded scores means any performance claim about it is unsupported. The RX 7800 XT also has a launch MSRP of 499 USD, while the Arc Pro B70 has a launch MSRP of 949 USD, a difference that the database records but this analysis does not expand upon.

The sensible reading of the data is this: the RX 7800 XT is the card with evidence behind it, and the Arc Pro B70 is a specification sheet waiting for validation. Choose the AMD card if you want verified results today. Choose the Intel card only if the 32 GB capacity and FP16 rate are non-negotiable requirements and you accept the lack of benchmark data.
