Intel Arc A570M vs Intel Arc Pro B65 Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison. The Intel Arc A570M has a single benchmark entry in the database: a Geekbench OpenCL score of 58,239 points. This places it in the 88th percentile of all GPUs tracked. The Intel Arc Pro B65, however, has no benchmark scores recorded. Its average benchmark score sits at zero, and its percentile versus all GPUs is 50, which is the median default for an unmeasured part. Consequently, a direct head-to-head comparison of measured performance is impossible from the database.

What can be analyzed is the A570M's position against its nearest rivals. The data shows the A570M is effectively bracketed by a narrow cluster of GPUs. Against the AMD Radeon RX 6950 XT, which holds an average score of 58,392, the A570M is 0.3% behind. Against the AMD Radeon RX 5600 OEM, with an average score of 58,085, the A570M is 0.3% ahead. Against the NVIDIA P102-100 (58,528 points), it trails by 0.5%, and against the AMD Radeon PRO V710 (58,657 points), it trails by 0.7%. These deltas are minuscule, indicating that in raw compute workloads, the A570M delivers performance within a 1% band of a range of very different GPU architectures.

The absence of any recorded benchmark for the B65 is a critical data point. The database shows zero wins for either item in head-to-head testing. The B65's theoretical specifications, which will be detailed in the architecture section, suggest a substantially higher compute ceiling than the A570M, but without measured scores, any performance conclusion must remain provisional. The data indicates the A570M is the only one of the two with a verified performance footprint.

Architecture Differences

The architectural gap between these two Intel GPUs is substantial, as the specifications reveal. The A570M is built on the DG2-256 chip, using the Xe-HPG architecture, and belongs to the Alchemist generation (Arc 5 Mobile). The B65 uses the BMG-G21 chip with the Xe2-HPG architecture, part of the Battlemage (Pro Series) generation. This generational shift brings a change in manufacturing process: the A570M is fabricated on a 6 nm node at TSMC, while the B65 moves to a 5 nm process at the same foundry.

The transistor counts and die sizes reflect this evolution. The A570M packs 11,500 million transistors on a 269 mm² die, yielding a transistor density of 42.8 million per square millimeter. The B65 contains 19,600 million transistors on a 272 mm² die, for a density of 72.1 million per square millimeter. The B65 nearly doubles the transistor count on a nearly identical die area, a direct consequence of the denser 5 nm process.

Compute resources differ sharply. The A570M has 2,048 shading units, 128 texture mapping units, and 64 raster operation units. It includes 16 ray tracing cores. The B65 expands these figures to 2,560 shading units, 160 TMUs, and 80 ROPs, with 20 ray tracing cores. The B65 also leads in raw throughput: it delivers 12.29 TFLOPS of FP32 compute versus 5.325 TFLOPS for the A570M. In FP16, the B65 achieves 24.58 TFLOPS versus 10.65 TFLOPS for the A570M, both running in a 2:1 ratio.

Memory configurations diverge even more dramatically. The A570M uses 8 GB of GDDR6 on a 128-bit bus, with a memory clock of 1750 MHz (14 Gbps effective) and a bandwidth of 224.0 GB/s. The B65 offers 32 GB of GDDR6 on a 256-bit bus, at 2375 MHz (19 Gbps effective), for a bandwidth of 608.0 GB/s. The B65 has four times the memory capacity and nearly three times the bandwidth. Pixel and texture rates follow suit: the A570M outputs 83.20 GPixel/s and 166.4 GTexel/s, while the B65 outputs 192.0 GPixel/s and 384.0 GTexel/s.

Clock speeds also separate the two. The A570M has a base clock of 900 MHz and a boost clock of 1300 MHz. The B65 runs at a constant 2400 MHz for both base and boost. Power envelopes are correspondingly different: the A570M is rated at 75 W and uses an IGP slot width, while the B65 is rated at 200 W, requires a dual-slot cooler, and uses a single 8-pin power connector. The B65 also demands a 550 W suggested power supply. Interface support advances on the B65: it uses PCIe 5.0 x16, whereas the A570M uses PCIe 4.0 x8. Display outputs differ as well, with the A570M being portable-device dependent and the B65 offering four DisplayPort 2.1 outputs. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The A570M launched in 2023, while the B65 has a 2026 release date.

Where Each One Wins

Based strictly on recorded data, the A570M wins in the only measurable category: it has a verified benchmark score, while the B65 has none. The A570M's 58,239 Geekbench OpenCL result places it at the 88th percentile of all GPUs, a strong showing for a mobile chip with a 75 W envelope. Its performance parity with the RX 6950 XT, RX 5600 OEM, P102-100, and PRO V710, all within a 0.7% band, indicates that the A570M is a capable compute engine for its power class.

The B65 wins on every theoretical architectural metric. Its FP32 throughput is roughly 2.3 times that of the A570M. Its memory bandwidth is 2.7 times higher. Its memory capacity is four times larger. Its pixel rate is 2.3 times higher, and its texture rate is also 2.3 times higher. The B65 also operates at nearly twice the clock speed, uses a newer architecture, and has more of every compute unit type. For workloads that scale with raw compute, memory capacity, or memory bandwidth, the B65's specifications indicate a decisive advantage.

The A570M wins on power efficiency in a strict sense: it draws 75 W versus 200 W, meaning it delivers its measured performance at a much lower power draw. The B65's specifications, however, suggest it delivers far more performance per watt in absolute terms, given the 2.3x FP32 increase against a 2.7x power increase. The A570M is also the only one of the two with a proven benchmark result, so for any application requiring verified performance, the A570M has the data, while the B65 remains unproven.

The Verdict

The data supports a split decision based on what is being measured. For verified, tested performance, the Intel Arc A570M is the only option with a recorded score. Its 58,239 Geekbench OpenCL result places it in the 88th percentile of all GPUs, and it trades blows within 0.7% of several AMD and NVIDIA parts. This makes it a proven quantity for compute workloads that fit within its 8 GB memory capacity and 224.0 GB/s bandwidth.

For workloads requiring large memory, high bandwidth, or maximum raw compute, the Intel Arc Pro B65 is the clear choice on paper. Its 32 GB memory capacity, 608.0 GB/s bandwidth, and 12.29 TFLOPS FP32 throughput are all far beyond the A570M's capabilities. The B65's newer Xe2-HPG architecture, denser 5 nm process, and higher clock speed of 2400 MHz all point to a significantly more capable part. The absence of benchmark data, however, means these advantages are theoretical. The B65's 200 W power draw and dual-slot cooler also indicate it is designed for a different class of system, one with room for a dedicated, power-hungry card.

The A570M suits mobile or low-power systems where the 75 W envelope and IGP form factor are mandatory. The B65 suits professional workstations or desktop builds where the 550 W suggested PSU and dual-slot footprint are acceptable. Users who need verified performance today should look at the A570M's results. Users who need maximum memory and compute headroom, and who can wait for benchmark validation, should consider the B65's specifications. The database currently shows one proven performer and one high-speculation part. That is the entirety of the recorded evidence.
