AMD Radeon 8040S vs Intel Arc Pro B70 Comparison

Where Each One Wins

The recorded database separates these two parts sharply by design intent. AMD Radeon 8040S is an integrated graphics processor (IGP) built into the Strix Halo chip, targeting portable devices where power draw and physical footprint dominate. Intel Arc Pro B70 is a dual-slot, discrete add-in board with its own 32 GB of GDDR6 memory, aimed at professional workstation workloads. The benchmark data confirms this split: the Radeon 8040S has seven recorded PassMark scores across DirectX 9, 10, 11, 12, G2D, G3D, and compute tests, while the Arc Pro B70 has no recorded benchmark scores in the database at this time. Consequently, the direct head-to-head comparison is asymmetrical, and the analysis must rely on the available measurements for the AMD part and the specification sheet for the Intel part.

For legacy DirectX performance, the Radeon 8040S shows its strongest relative showing. Its PassMark DirectX 9 score of 134 is the highest among its own benchmark suite, indicating that older API workloads run disproportionately well on this architecture. The DirectX 11 score of 80 is second-highest, while DirectX 10 (48) and DirectX 12 (47) are nearly identical and notably lower. This pattern suggests the RDNA 3.5 design retains solid compatibility with older graphics APIs, but the modern DirectX 12 path does not scale as strongly. The compute score of 5138 is substantial relative to the graphics scores, reflecting the shader-heavy design.

The Intel Arc Pro B70, by contrast, has no benchmark entries in the database, so its wins cannot be quantified from recorded measurements. The specification sheet, however, indicates a much larger execution resource pool: 4096 shading units, 256 texture mapping units, 128 render output units, and 32 ray tracing cores. These numbers are four times the Radeon 8040S in shading units, TMUs, and ROPs, and double in ray tracing cores. For professional rendering, compute, and ray-traced workloads, the Arc Pro B70 is clearly the more capable part on paper, but the absence of benchmark data means no empirical win can be assigned.

Architecture Differences

The two accelerators come from different manufacturers and different architectural generations. AMD Radeon 8040S uses the RDNA 3.5 architecture on a 4 nm TSMC process, with a die size of 308 mm². It is part of the Navi Mobile (RX 8000M) generation, and its chip is codenamed Strix Halo. The Intel Arc Pro B70 uses the Xe2-HPG architecture on a 5 nm TSMC process, with a larger die at 368 mm². It belongs to the Battlemage (Pro Series) generation, and its chip is BMG-G31. Both use TSMC as the foundry, but the AMD part is on a smaller process node, which typically allows higher transistor density or lower power for the same complexity, though the database records transistor counts as unknown for both.

The memory architecture is fundamentally different. Radeon 8040S uses System Shared memory, meaning it has no dedicated VRAM and instead borrows from the host system's main memory. The memory type, bus width, and bandwidth are all listed as System Shared or System Dependent, with no fixed figures. This is typical for an integrated GPU, where the memory controller and bandwidth are shared with the CPU. Intel Arc Pro B70, in contrast, has 32 GB of dedicated GDDR6 memory on a 256-bit bus, with a bandwidth of 608.0 GB/s. The memory clock is 2375 MHz with 19 Gbps effective data rate. This dedicated high-bandwidth memory is a critical differentiator for bandwidth-sensitive workloads like high-resolution textures, large datasets, and compute tasks.

Clock behavior also differs. Both parts share the same boost clock of 2800 MHz, but the base clock is much lower on the Radeon 8040S at 1295 MHz, versus 2280 MHz on the Arc Pro B70. The AMD part's lower base clock and shared memory suggest it is designed to run at lower sustained power, consistent with its 55 W TDP. The Intel part has a 230 W TDP, a dual-slot cooler, and requires a single 8-pin power connector, with a suggested 550 W power supply. The Radeon 8040S has no power connectors and is an IGP, meaning it draws power through the motherboard socket. The bus interface is identical for both: PCIe 5.0 x16.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for this pair, and the Intel Arc Pro B70 has zero recorded scores. The only quantitative comparisons come from the Radeon 8040S's own benchmark suite and its nearest rivals in the database. The Radeon 8040S achieves a PassMark G3D score of 10578, a G2D score of 1052, and a compute score of 5138. Its average benchmark score across all tests is 2440. The percentile versus all GPUs is 17, meaning it outperforms 17% of all recorded graphics cards, which is a low placement. The nearest rival in the database is the NVIDIA GeForce 710M with an average score of 2433, a delta of 0.3% in favor of the Radeon. The Intel HD Graphics 610 scores 2425 (0.6% behind), the NVIDIA GeForce GT 710M scores 2422 (0.7% behind), and the AMD Radeon RX 7400 scores 2467 (1.1% ahead of the Radeon 8040S). These deltas are all within a narrow band, indicating that the Radeon 8040S performs at the very low end of the desktop GPU spectrum, roughly on par with entry-level integrated graphics from several years ago.

For the Arc Pro B70, the database records an average benchmark score of 0 and no rivals, because no measurements exist. The percentile is 50, which is a placeholder rather than a meaningful percentile, given the absence of scores. Without recorded data, no head-to-head numbers can be cited for the Intel part. The only quantitative wins for the Radeon 8040S are its own scores, which show a strong compute result relative to its graphics scores, and its DirectX 9 result of 134 being the highest in its suite.

Specification Differences

The specification sheet reveals substantial differences across nearly every field, with only a few shared values. Both parts use PCIe 5.0 x16 bus interface, support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both have no tensor cores listed. The boost clock is identical at 2800 MHz.
