AMD Ryzen Z1 Extreme GPU vs Intel Arc Pro B65 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results for the AMD Ryzen Z1 Extreme GPU against the Intel Arc Pro B65. Both entries list an average benchmark score of 0 and zero wins in their respective benchmark suites. The percentile versus all GPUs is identical for both parts at 50, placing them at the median of the tracked database population, but this does not represent a comparative performance measurement between the two.

Without head-to-head results, the available computed performance figures provide the only quantifiable basis for comparison. The AMD Ryzen Z1 Extreme GPU delivers 8.294 TFLOPS of FP32 compute, while the Intel Arc Pro B65 delivers 12.29 TFLOPS. That places the Intel part approximately 48% higher in raw single-precision throughput. The FP16 figures follow the same pattern: 16.59 TFLOPS for AMD versus 24.58 TFLOPS for Intel, again a 48% advantage for the Intel product. Pixel throughput heavily favors Intel as well, with 192.0 GPixel/s against 86.40 GPixel/s, a margin of roughly 122%. Texture rate shows a similar gap, 384.0 GTexel/s for Intel versus 129.6 GTexel/s for AMD, which is roughly three times the AMD number.

These are theoretical peak rates, not measured application results, and the database records no benchmark data confirming how these figures translate into real-world performance. The Intel part also carries substantially more memory bandwidth, 608.0 GB/s compared to 51.20 GB/s, which is approximately eleven times higher. Memory capacity differs as well: 32 GB versus 16 GB. The AMD part counters with a much lower power envelope, 30 W against 200 W, and a smaller physical footprint. The AMD component is listed with dimensions of 280 mm length, 111 mm height, and 21 mm width, while the Intel card has no recorded dimensions. The AMD product also requires no power connectors, whereas the Intel card uses a single 8-pin connector and lists a 550 W suggested power supply.

Architecture Differences

The AMD Ryzen Z1 Extreme GPU is built on the RDNA 3.0 architecture, using the Phoenix chip. The Intel Arc Pro B65 uses the Xe2-HPG architecture with the BMG-G21 chip and belongs to the Battlemage Pro Series generation. Both chips are fabricated by TSMC, but at different process nodes: AMD uses 4 nm, Intel uses 5 nm.

The transistor counts and die sizes reveal different design philosophies. AMD packs 25,390 million transistors into a 178 mm² die, resulting in a transistor density of 142.6M per square millimeter. Intel places 19,600 million transistors on a 272 mm² die, yielding 72.1M per square millimeter. The AMD chip is therefore nearly twice as dense, while the Intel chip is physically larger but less dense.

The compute units differ sharply. AMD provides 768 shading units, 48 texture mapping units, 32 raster operation units, and 12 ray tracing cores. Intel provides 2560 shading units, 160 texture mapping units, 80 raster operation units, and 20 ray tracing cores. These structural differences align with the computed throughput gaps. The AMD part has no tensor core count recorded, and neither does the Intel part. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature support matches.

Memory architecture is fundamentally different. AMD uses LPDDR5 memory with a 64-bit bus, while Intel uses GDDR6 with a 256-bit bus. The resulting bandwidth difference is substantial, 51.20 GB/s versus 608.0 GB/s. The AMD product is classified as a console GPU generation, while the Intel product is a professional series card in the Battlemage lineup.

The two products differ across nearly every recorded specification field. Process node: AMD at 4 nm, Intel at 5 nm. Transistors: 25,390 million for AMD, 19,600 million for Intel. Die size: 178 mm² for AMD, 272 mm² for Intel. Transistor density: 142.6M per mm² versus 72.1M per mm².

Clock behavior is distinct. The AMD part has an 800 MHz base clock and a 2700 MHz boost clock. The Intel part has a fixed 2400 MHz base and boost clock. Memory clocks also differ: AMD lists 800 MHz with 6.4 Gbps effective, Intel lists 2375 MHz with 19 Gbps effective.

Memory capacity, type, bus width, and bandwidth all differ. AMD: 16 GB LPDDR5, 64-bit bus, 51.20 GB/s. Intel: 32 GB GDDR6, 256-bit bus, 608.0 GB/s.

The Verdict

The data supports a clear split based on intended use. The Intel Arc Pro B65 dominates every computed throughput metric: higher FP32, FP16, pixel rate, texture rate, memory capacity, and memory bandwidth. It also carries more shading units, TMUs, ROPs, and ray tracing cores. Any workload dependent on raw compute, large memory buffers, or high bandwidth aligns with the Intel product.

The AMD Ryzen Z1 Extreme GPU holds advantages in power efficiency and physical integration. Its 30 W TDP is a fraction of the Intel card's 200 W TDP. It requires no external power connectors and lists no suggested power supply. The AMD part is a compact unit with recorded dimensions of 280 mm by 111 mm by 21 mm, whereas the Intel card only specifies a dual-slot form factor. The AMD chip also uses a denser 4 nm process and packs more transistors per square millimeter.

The launch MSRP for the AMD part is 699 USD, recorded once here. The Intel part has no launch MSRP in the database.

Neither product shows benchmark wins in the database, and both have an average benchmark score of 0. The percentile ranking of 50 for both parts indicates median placement among all tracked GPUs, but no head-to-head results exist to confirm actual application performance. The verdict rests on specification analysis alone: Intel for compute and memory throughput, AMD for low power and compact integration.
