AMD Ryzen Z1 GPU vs Intel Arc Pro B65 Comparison

AMD Ryzen Z1 GPU and Intel Arc Pro B65 occupy different positions in the database, with the former designed as a low-power embedded solution and the latter as a professional workstation card. The recorded data shows no overlapping benchmark wins, as the two products target entirely distinct use cases. The AMD Ryzen Z1 GPU is a 30 W part with 16 GB of LPDDR5 memory, while the Intel Arc Pro B65 is a 200 W card with 32 GB of GDDR6 memory, and this disparity in power and memory configuration defines their respective roles.

The Verdict

The AMD Ryzen Z1 GPU is for systems that require graphics capability within a very tight power envelope. The data shows a 30 W TDP, no power connectors, and no display outputs, indicating the chip is meant to be integrated into a host device rather than installed as a standalone graphics card. The 16 GB of LPDDR5 memory on a 64-bit bus delivers 51.20 GB/s of bandwidth, which is sufficient for memory-intensive workloads that do not demand high throughput. The Intel Arc Pro B65 is the opposite: a 200 W dual-slot card with a single 8-pin power connector, a suggested 550 W power supply, and four DisplayPort 2.1 outputs. This is a professional GPU meant to be installed in a workstation chassis and connected to multiple high-resolution displays.

Benchmark results indicate the Intel part holds a commanding lead in raw compute. The Arc Pro B65 delivers 12.29 TFLOPS of FP32 performance versus 2.560 TFLOPS for the Ryzen Z1 GPU, a difference of roughly 4.8 times. The Intel card also has 2560 shading units against 256 for the AMD chip, and 20 ray tracing cores versus 4. The database places both products at the 50th percentile among all GPUs, but that figure reflects the absence of recorded benchmark scores for either part. The practical verdict is straightforward: the Ryzen Z1 GPU belongs in a handheld or embedded device, while the Arc Pro B65 belongs in a desktop workstation. The AMD chip is a 2023 release with a launch MSRP of 599 USD, while the Intel card is dated for 2026 in the database.

Where Each One Wins

The AMD Ryzen Z1 GPU wins in efficiency and integration. The 30 W TDP means it can be cooled passively or with a minimal cooling solution, and the absence of power connectors and display outputs shows it is not designed to be a user-serviceable component. The 4 nm process node from TSMC gives it a transistor density of 142.6 million transistors per square millimeter, which is nearly double the 72.1M / mm² of the Intel part. The smaller die size of 178 mm² against 272 mm² for the Intel card reinforces that the AMD chip is built for compact, power-constrained environments.

The Intel Arc Pro B65 wins in every performance category recorded in the database. Memory bandwidth is the most dramatic difference: 608.0 GB/s versus 51.20 GB/s, a 11.9 times advantage. The Intel card has a 256-bit memory bus versus 64-bit, and 32 GB of GDDR6 memory against 16 GB of LPDDR5. Pixel throughput is 192.0 GPixel/s versus 20.00 GPixel/s, and texture throughput is 384.0 GTexel/s versus 40.00 GTexel/s. The Intel part also has 160 texture mapping units and 80 render output units, compared to 16 TMUs and 8 ROPs on the AMD chip. The Arc Pro B65 uses a PCIe 5.0 x16 interface, while the Ryzen Z1 GPU has no recorded bus interface, further confirming the Intel card is a full-sized expansion card.

Architecture Differences

The AMD Ryzen Z1 GPU uses the Phoenix chip with RDNA 3.0 architecture, built on a 4 nm TSMC process. The Intel Arc Pro B65 uses the BMG-G21 chip with Xe2-HPG architecture, built on a 5 nm TSMC process. Both are TSMC products, but the AMD chip has a higher transistor density at 142.6M / mm² versus 72.1M / mm², despite having more total transistors at 25,390 million versus 19,600 million. The die size tells the opposite story: the Intel chip is larger at 272 mm², while the AMD chip is 178 mm².

The memory subsystems are entirely different. The AMD part uses LPDDR5 at 6.4 Gbps effective on a 64-bit bus, yielding 51.20 GB/s. The Intel part uses GDDR6 at 19 Gbps effective on a 256-bit bus, yielding 608.0 GB/s. Clock behavior also differs: the AMD chip has a base clock of 1500 MHz and a boost of 2500 MHz, while the Intel chip has a fixed clock of 2400 MHz for both base and boost. The AMD chip's memory clock is 800 MHz, while the Intel chip's memory clock is 2375 MHz.

Compute resources scale accordingly. The AMD chip has 256 shading units, 16 TMUs, 8 ROPs, and 4 ray tracing cores. The Intel chip has 2560 shading units, 160 TMUs, 80 ROPs, and 20 ray tracing cores. Neither part has tensor cores recorded in the database. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD chip has no display outputs, while the Intel card has 4x DisplayPort 2.1. The AMD part has no slot width or power connector data beyond "None," while the Intel card is dual-slot with a single 8-pin connector.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for these two GPUs, and neither has an average benchmark score recorded. The comparison must therefore rely on the specification-derived performance metrics. The largest recorded advantage for the Intel Arc Pro B65 is in memory bandwidth: 608.0 GB/s versus 51.20 GB/s, an 11.9 times difference. This single figure explains the professional positioning of the Intel card, as memory bandwidth is the limiting factor for many compute and rendering workloads.

FP32 compute shows a 4.8 times advantage for the Intel card at 12.29 TFLOPS versus 2.560 TFLOPS. FP16 compute follows the same pattern at 24.58 TFLOPS versus 5.120 TFLOPS, both recorded as 2:1 rates. Pixel rate is 192.0 GPixel/s for Intel versus 20.00 GPixel/s for AMD, a 9.6 times difference. Texture rate is 384.0 GTexel/s versus 40.00 GTexel/s, a 9.6 times difference. These ratios are consistent with the scaling of the underlying hardware: the Intel card has 10 times the shading units, 10 times the TMUs, and 10 times the ROPs.

The AMD Ryzen Z1 GPU does hold advantages in process technology and transistor density. The 4 nm node versus 5 nm gives the AMD chip a higher transistor density of 142.6M / mm² versus 72.1M / mm². The AMD chip also has a higher boost clock of 2500 MHz versus the Intel card's fixed 2400 MHz. However, the AMD chip's base clock is lower at 1500 MHz, and its memory clock is 800 MHz versus 2375 MHz. The Intel card's boost clock being identical to its base clock at 2400 MHz suggests a steady-state operating point, while the AMD chip scales from 1500 MHz to 2500 MHz.
