Intel Arc Pro B70 vs NVIDIA GeForce RTX 4080 Max-Q Comparison

Where Each One Wins

The recorded data shows a clear split in intended use between these two GPUs, and it is not a conventional desktop versus laptop comparison. The Intel Arc Pro B70 is a professional workstation card with a 230 W TDP, dual-slot cooler, and a single 8-pin power connector. The NVIDIA GeForce RTX 4080 Max-Q is a 60 W mobile part, classified as an IGP (integrated GPU for laptops), with no power connectors and dimensions that are portable-device dependent. Neither part has any head-to-head benchmark victories recorded in the database, and both sit at the 50th percentile among all GPUs.

For raw compute throughput, the Intel card leads in several categories. Its FP32 output is 22.94 TFLOPS versus 20.04 TFLOPS for the NVIDIA part. The Arc Pro B70 also delivers substantially higher pixel and texture rates: 358.4 GPixel/s against 108.0 GPixel/s, and 716.8 GTexel/s against 313.2 GTexel/s. These numbers point to the Intel card being the stronger choice for compute-heavy workloads, particularly those that stress fill rate and texture processing.

The NVIDIA part wins in other structural ways. It has 7424 shading units compared to 4096 on the Intel card, and 58 RT cores versus 32. It also carries 232 tensor cores, a feature entirely absent from the Intel specification. For applications that leverage NVIDIA's tensor core ecosystem, the RTX 4080 Max-Q holds the advantage, even with its lower raw FP32 throughput.

The memory configuration also separates the two. The Arc Pro B70 has 32 GB of GDDR6 on a 256-bit bus, yielding 608.0 GB/s of bandwidth. The RTX 4080 Max-Q has 12 GB on a 192-bit bus for 432.0 GB/s. Larger memory capacity and higher bandwidth favor the Intel card in scenarios where datasets exceed 12 GB, such as large model inference or high-resolution rendering. The NVIDIA part's smaller memory pool may bottleneck such workloads, but its lower power draw allows deployment in thin-and-light systems where the Intel card physically cannot fit.

Architecture Differences

The Intel Arc Pro B70 uses the BMG-G31 chip built on TSMC's 5 nm process, with an architecture designated Xe2-HPG under the Battlemage Pro Series generation. Its die size is 368 mm², and transistor count is listed as unknown. The NVIDIA GeForce RTX 4080 Max-Q uses the AD104 chip, also on TSMC's 5 nm process, under the Ada Lovelace architecture within the GeForce 40 Mobile generation. Its die is smaller at 294 mm², and it carries 35,800 million transistors, giving a transistor density of 121.8 million per mm².

Clock behavior differs sharply. The Intel card runs a base clock of 2280 MHz and boosts to 2800 MHz. The NVIDIA part runs a base of only 795 MHz and boosts to 1350 MHz. That clock gap explains part of the fill-rate difference despite the NVIDIA part having more shading units. The Intel card's memory runs at 2375 MHz with 19 Gbps effective, while the NVIDIA memory runs at 2250 MHz with 18 Gbps effective.

The Intel part supports PCIe 5.0 x16, while the NVIDIA part uses PCIe 4.0 x16. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ: the Intel card offers 1x HDMI 2.1a and 3x DisplayPort 2.1, while the NVIDIA card's outputs are portable-device dependent, meaning they vary by laptop implementation.

Feature sets diverge in tensor capabilities. The NVIDIA card includes 232 tensor cores, the Intel card has none listed. RT core counts also differ, 58 versus 32, though the Intel part has more TMUs (256 versus 232) and ROPs (128 versus 80). The NVIDIA part uses a 1:1 FP16 to FP32 ratio, both at 20.04 TFLOPS. The Intel card uses a 2:1 ratio, delivering 45.88 TFLOPS FP16 against 22.94 TFLOPS FP32.

Head-to-Head Benchmarks

The database records no head-to-head benchmark scores between these two parts, and neither has an average benchmark score or nearest rivals listed. The comparison must therefore rely on the specification-derived rates and throughput figures already recorded.

The largest margin in the data is pixel fill rate. The Intel Arc Pro B70 outputs 358.4 GPixel/s, which is 3.3 times the 108.0 GPixel/s of the RTX 4080 Max-Q. That gap stems from the Intel card's 128 ROPs and 2800 MHz boost clock against the NVIDIA part's 80 ROPs and 1350 MHz boost. In texture rate, Intel leads with 716.8 GTexel/s versus 313.2 GTexel/s, a 2.3x advantage driven by 256 TMUs at a much higher clock.

Memory bandwidth favors Intel by a factor of 1.4, with 608.0 GB/s versus 432.0 GB/s. The 256-bit bus versus 192-bit bus is the primary driver, compounded by the slightly higher memory clock. FP32 throughput shows a narrower gap: 22.94 TFLOPS versus 20.04 TFLOPS, a 14.5% lead for Intel. FP16 is where Intel stretches further, at 45.88 TFLOPS versus 20.04 TFLOPS, a 2.3x advantage because of the 2:1 ratio versus the 1:1 ratio.

The NVIDIA part counters with a 1.8x advantage in shading units (7424 versus 4096) and a 1.8x advantage in RT cores (58 versus 32). Tensor cores exist only on the NVIDIA side at 232. Power consumption is the starkest differentiator: 60 W versus 230 W, a 3.8x difference in favor of the NVIDIA part. That power envelope allows the RTX 4080 Max-Q to operate as an IGP with no power connectors, whereas the Intel card requires a dual-slot cooler and a 550 W suggested power supply.

The Verdict

The data indicates two products for entirely different physical environments. The Intel Arc Pro B70 is a full-size, dual-slot workstation card with a 230 W TDP, 32 GB memory, and PCIe 5.0. It wins on every throughput metric except shading unit count and RT core count: higher pixel rate, higher texture rate, higher memory bandwidth, higher FP32, and substantially higher FP16. Its launch MSRP is 949 USD. For compute tasks that fit within its power budget and physical footprint, the Intel card is the stronger performer.

The NVIDIA GeForce RTX 4080 Max-Q is a 60 W mobile part. It cannot match the Intel card's fill rates or memory capacity, but it offers more shading units (7424 versus 4096), more RT cores (58 versus 32), and the only tensor core implementation in this comparison. Its smaller 12 GB memory pool and 192-bit bus limit large dataset work, but its power draw is 3.8x lower, enabling deployment in portable devices with no external power connectors.

The selection depends on the physical system, not just performance. A desktop or workstation chassis with room for a 267 mm dual-slot card and a 550 W PSU should use the Arc Pro B70 for higher compute throughput and double-precision-friendly FP16 work. A laptop or compact portable device must use the RTX 4080 Max-Q, accepting lower raw rates in exchange for a 60 W envelope and tensor core support. Both parts sit at the 50th percentile among all GPUs, indicating mid-pack standing overall, but their design targets are mutually exclusive.
