AMD Radeon AI PRO R9700S vs Intel Arc Pro B50 Comparison

The Verdict

The database places the AMD Radeon AI PRO R9700S and the Intel Arc Pro B50 in different performance tiers entirely. The R9700S sits at the 50th percentile among all GPUs, while the Arc Pro B50 rests at the 17th percentile. This percentile gap reflects a fundamental difference in compute capacity, memory resources, and power delivery. The R9700S targets workloads requiring large memory pools and high throughput, while the Arc Pro B50 addresses lighter professional tasks with modest power requirements.

For users processing large datasets, rendering complex scenes, or running GPU-accelerated compute, the R9700S is the only viable option from this data. Its 32 GB memory capacity and 644.6 GB/s bandwidth provide the resources needed for memory-intensive operations. The Arc Pro B50, with 16 GB memory and 224.0 GB/s bandwidth, serves users with lighter workloads who prioritize low power draw and compact physical dimensions.

The Arc Pro B50 carries a launch MSRP of 349 USD, a figure the database records for that product alone. The R9700S has no recorded launch MSRP. The Arc Pro B50 draws 70 W and requires no auxiliary power connectors, whereas the R9700S draws 300 W and uses a single 16-pin connector. These power characteristics dictate deployment scenarios: the B50 fits into systems with minimal power headroom, while the R9700S demands robust power delivery.

Architecture Differences

The two GPUs come from different foundries and process nodes. The R9700S uses TSMC's 4 nm process with a die size of 357 mm² and 53,900 million transistors. The Arc Pro B50 uses TSMC's 5 nm process with a die size of 272 mm² and 19,600 million transistors. The R9700S achieves a transistor density of 151.0 million transistors per mm², nearly double the B50's 72.1 million per mm².

The R9700S implements AMD's RDNA 4.0 architecture on the Navi 48 chip, part of the Radeon Pro Navi (Navi IV Series) generation. The Arc Pro B50 implements Intel's Xe2-HPG architecture on the BMG-G21 chip, part of the Battlemage (Pro Series) generation. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility matches.

Compute resources differ substantially. The R9700S carries 4,096 shading units, 256 texture mapping units, 128 render output units, and 64 ray tracing cores. The Arc Pro B50 carries 2,048 shading units, 128 texture mapping units, 16 render output units, and 16 ray tracing cores. The R9700S doubles the shading units and TMUs, and quadruples the ROPs and RT cores relative to the B50.

Memory subsystems also diverge. The R9700S supports 32 GB GDDR6 on a 256-bit bus, with memory clocked at 2518 MHz (20.1 Gbps effective). The B50 supports 16 GB GDDR6 on a 128-bit bus, with memory clocked at 1750 MHz (14 Gbps effective). The R9700S delivers 644.6 GB/s bandwidth versus 224.0 GB/s for the B50, a 2.9x advantage.

The R9700S connects via PCIe 5.0 x16, while the B50 uses PCIe 5.0 x8. Display outputs also differ: the R9700S provides 4x DisplayPort 2.1a, while the B50 provides 4x mini-DisplayPort 2.1. Physical dimensions favor the B50 for compact builds: the R9700S measures 267 mm by 109 mm by 39 mm, while the B50 measures 167 mm by 69 mm by 40 mm.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between the R9700S and the Arc Pro B50. The R9700S has zero recorded benchmark scores and zero wins in head-to-head comparisons. The Arc Pro B50, however, has eight recorded benchmark scores across multiple test suites.

The B50's 3DMark Steel Nomad DX12 score of 1604 indicates its DirectX 12 gaming performance. PassMark results show a G3D score of 12,553, a G2D score of 717, and a GPU compute score of 6,037. Legacy DirectX tests record 58 for DirectX 10, 100 for DirectX 11, 64 for DirectX 12, and 144 for DirectX 9.

The R9700S lacks any recorded benchmark data, so direct numerical comparison remains impossible from the database. However, architectural specifications provide a basis for relative assessment. The R9700S computes 47.84 TFLOPS FP32 versus 10.65 TFLOPS for the B50, a 4.5x difference. Pixel throughput measures 373.8 GPixel/s for the R9700S versus 41.60 GPixel/s for the B50, a 9.0x difference. Texture throughput measures 747.5 GTexel/s versus 332.8 GTexel/s, a 2.2x difference.

The R9700S's ROP count of 128 versus 16 explains the massive pixel rate gap. Its RT core count of 64 versus 16 indicates substantially higher ray tracing throughput capability. The B50's FP16 advantage comes from its 2:1 ratio, delivering 21.30 TFLOPS from 10.65 TFLOPS FP32, but this still falls below the R9700S's 47.84 TFLOPS FP16.

Where Each One Wins

The Arc Pro B50 wins in power efficiency and physical footprint. Its 70 W TDP requires no auxiliary power connectors and a 250 W suggested PSU, enabling deployment in compact systems where power delivery is constrained. Its 167 mm length and 69 mm height fit into small chassis that cannot accommodate the R9700S's 267 mm length and 109 mm height. The B50's PCIe 5.0 x8 interface still provides modern bandwidth while reducing lane requirements.

The R9700S wins decisively in compute capacity. Its 47.84 TFLOPS FP32 and matching 47.84 TFLOPS FP16 provide 4.5x the FP32 throughput and 2.2x the FP16 throughput of the B50. Memory bandwidth of 644.6 GB/s versus 224.0 GB/s gives the R9700S a 2.9x advantage for bandwidth-bound workloads. The 32 GB memory capacity doubles the B50's 16 GB, allowing larger datasets to reside on the GPU without host memory transfers.

For rendering workloads, the R9700S's 64 RT cores versus 16 provide a significant ray tracing advantage. Its 128 ROPs versus 16 deliver 9.0x the pixel fill rate, benefiting high-resolution output and multi-display configurations. The R9700S's PCIe 5.0 x16 interface provides double the lane width of the B50's x8 interface for host data transfer.

The B50's release date of 2025-09-04 precedes the R9700S's 2025-12-10 release by roughly three months, making it available earlier in the product cycle. Both GPUs remain in active production status. The B50's nearest rivals in the database include the NVIDIA GeForce GT 1030 (average score 2662, delta -0.1%), NVIDIA Quadro K1100M (2664, delta -0.2%), NVIDIA GeForce GT 440 (2645, delta 0.6%), and NVIDIA GeForce RTX 5070 SUPER (2690, delta -1.1%). These deltas, all within 1.1% of the B50's 2660 average score, indicate the B50 clusters tightly with entry-level discrete GPUs.

The R9700S's 50th percentile ranking versus the B50's 17th percentile ranking places them 33 percentile points apart. This gap exceeds any single specification difference and reflects the cumulative impact of architecture, memory, and compute resource disparities.
