Intel Arc A310E vs Intel Arc Pro B70 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark entries for the Intel Arc A310E and the Intel Arc Pro B70. Both cards show an average benchmark score of 0 in the database, and the wins counter shows zero for each side. Consequently, the comparison rests entirely on specification analysis and computed capabilities derived from the listed hardware parameters.

The most decisive gap appears in raw compute throughput. The Arc Pro B70 delivers 22.94 TFLOPS of FP32 performance, while the Arc A310E delivers 3.072 TFLOPS. That places the B70 at roughly 7.5 times the FP32 throughput of the A310E. In FP16, the B70 reaches 45.88 TFLOPS, while the A310E reaches 6.144 TFLOPS, again a factor of approximately 7.5. These figures come directly from the recorded clock rates and shading unit counts: the B70 runs 4096 shading units at a 2800 MHz boost clock, whereas the A310E runs 768 shading units at a 2000 MHz boost clock.

Memory bandwidth follows a similar pattern. The Arc Pro B70 uses a 256 bit bus with GDDR6 at 19 Gbps effective, yielding 608.0 GB/s. The Arc A310E uses a 64 bit bus with GDDR6 at 15.5 Gbps effective, yielding 124.0 GB/s. The B70 therefore provides roughly 4.9 times the memory bandwidth. Capacity differs even more sharply: 32 GB versus 4 GB, an 8 fold difference. For workloads that spill past 4 GB of frame buffer, the A310E cannot operate at all while the B70 continues with ample headroom.

Pixel and texture throughput also favor the B70 heavily. The B70 renders at 358.4 GPixel/s and 716.8 GTexel/s, against 32.00 GPixel/s and 64.00 GTexel/s for the A310E. These are 11.2 times and 11.2 times the A310E rates, respectively. The B70 also carries 32 ray tracing cores versus 6, a 5.3 times difference in RT core count.

Clock speeds tell a subtler story. The A310E runs a flat 2000 MHz base and boost, with no boost headroom above its base. The B70 runs 2280 MHz base and 2800 MHz boost, meaning it can raise clocks by 520 MHz under load. The B70 memory clock is 2375 MHz against 1937 MHz for the A310E, and effective memory speed is 19 Gbps versus 15.5 Gbps.

Process node and die characteristics favor the newer card. The B70 uses a 5 nm TSMC process with a 368 mm² die. The A310E uses a 6 nm TSMC process with a 157 mm² die. The A310E lists 7,200 million transistors and a transistor density of 45.9M per mm², while the B70 lists transistor count as unknown. The B70 die is larger despite the smaller process node, reflecting a much bigger GPU.

Power and physical requirements differ by a wide margin. The A310E consumes 75 W TDP with no power connectors and a suggested 250 W PSU, in a single-slot, 168 mm long, 69 mm tall, 20 mm wide package. The B70 consumes 230 W TDP with a single 8-pin connector and a suggested 550 W PSU, in a dual-slot, 267 mm long, 110 mm tall, 39 mm wide package. The B70 is longer, taller, and thicker, and requires more than twice the board power.

Interface and display output also separate the two. The A310E uses PCIe 4.0 x8, while the B70 uses PCIe 5.0 x16, which provides up to four times the bus bandwidth in theory. The A310E outputs four mini-DisplayPort 2.0 connections. The B70 outputs one HDMI 2.1a and three DisplayPort 2.1 connections. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Production status and release timing differ as well. The A310E is marked end-of-life, released on 2024-03-31, with a predecessor listed as Xe Graphics and a successor listed as Battlemage. The B70 has no production status listed and was released on 2026-03-25. The A310E belongs to the Alchemist (Arc 3) generation with the DG2-128 chip and Xe-HPG architecture. The B70 belongs to the Battlemage (Pro Series) generation with the BMG-G31 chip and Xe2-HPG architecture. The B70 carries a launch MSRP of 949 USD.

The Verdict

From the recorded data, the Intel Arc Pro B70 is the dominant card in every measured compute category. FP32 is 22.94 TFLOPS against 3.072 TFLOPS. FP16 is 45.88 TFLOPS against 6.144 TFLOPS. Memory bandwidth is 608.0 GB/s against 124.0 GB/s. Pixel rate is 358.4 GPixel/s against 32.00 GPixel/s. Texture rate is 716.8 GTexel/s against 64.00 GTexel/s. Ray tracing cores number 32 against 6. Shading units number 4096 against 768. TMUs number 256 against 32. ROPs number 128 against 16. Memory capacity is 32 GB against 4 GB. Bus width is 256 bit against 64 bit. The B70 wins on every single one of these fields.

The A310E wins only in physical footprint, power draw, and interface simplicity. It draws 75 W against 230 W, needs no power connector, fits a single slot, and measures 168 mm by 69 mm by 20 mm. The B70 draws 230 W, needs one 8-pin connector, occupies a dual slot, and measures 267 mm by 110 mm by 39 mm. The A310E also has a smaller die at 157 mm² versus 368 mm², and a lower suggested PSU at 250 W versus 550 W.

Given the absence of benchmark scores, the verdict follows the specification deltas. Any workload that can use the B70's additional memory, bandwidth, or shading units will favor it decisively. Any workload bounded by the A310E's 4 GB frame buffer will simply fail on the A310E where the B70 continues. The A310E's only clear advantage is for constrained systems where 75 W, no power connector, and single-slot fit are mandatory.

The data does not support any scenario where the A310E outperforms the B70 in throughput. The B70 is the choice for raw performance, and the A310E is the choice for minimal power and space envelopes. There is no middle ground in the recorded numbers.

Where Each One Wins

The Arc Pro B70 wins in every performance-oriented use case implied by the hardware. Large frame buffers matter for rendering scenes that exceed 4 GB, and the B70 provides 32 GB. High bandwidth matters for texture streaming and compute kernels that move large data sets, and the B70 provides 608.0 GB/s. High shading unit counts matter for general compute and raster workloads, and the B70 provides 4096 units. High texture and pixel rates matter for fill-bound scenes, and the B70 provides 716.8 GTexel/s and 358.4 GPixel/s. The 32 ray tracing cores give the B70 a clear path for ray-traced workloads, while the A310E's 6 cores limit such work to light effects. The PCIe 5.0 x16 interface gives the B70 more host bandwidth for data transfer, which matters when GPU memory is used as a compute scratchpad. The dual-slot cooler and 230 W TDP indicate the B70 is designed for sustained high-load operation in a workstation chassis.

The Arc A310E wins in low-power and space-constrained deployments. The 75 W TDP and no power connector mean it can run in systems without auxiliary GPU power. The single-slot, 168 mm length, 69 mm height, and 20 mm width allow installation in compact chassis. The 250 W suggested PSU means the host system does not need a large power supply. The 4 GB memory and 64 bit bus are sufficient for light display output and modest compute tasks. The four mini-DisplayPort 2.0 outputs support multi-monitor setups. The 2000 MHz flat clock suggests predictable thermal behavior under load. The end-of-life status means it is a legacy option for existing deployments.

In short, the B70 is for workloads that need capacity and speed, while the A310E is for systems that need a small, low-power GPU with multiple display outputs.
