AMD Radeon RX 7700S vs Intel Arc Pro B70 Comparison

Architecture Differences

The AMD Radeon RX 7700S and Intel Arc Pro B70 represent two fundamentally different design philosophies in the mobile and professional graphics space. The RX 7700S is built on the Navi 33 chip using the RDNA 3.0 architecture, with the codename Hotpink Bonefish. It belongs to the Navi Mobile (RX 7000M) generation and is manufactured on a 6 nm process at TSMC. The chip contains 13,300 million transistors on a 204 mm² die, resulting in a transistor density of 65.2M per mm².

The Intel Arc Pro B70 uses the BMG-G31 chip based on the Xe2-HPG architecture, belonging to the Battlemage (Pro Series) generation. It is built on a 5 nm process at TSMC, which is a smaller node than the AMD part. The Intel die is substantially larger at 368 mm², but the transistor count is listed as unknown in the database, and no density figure is available. This makes a direct transistor-level comparison impossible from the recorded data.

Clock behavior differs markedly between the two. The RX 7700S has a base clock of 1500 MHz, a boost clock of 2500 MHz, and a game clock of 2200 MHz. The Arc Pro B70 runs considerably higher with a base of 2280 MHz and a boost of 2800 MHz. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature parity is confirmed in the database.

Memory architecture is one of the largest separations. The RX 7700S uses 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth with memory clocked at 2250 MHz (18 Gbps effective). The Arc Pro B70 ships with 32 GB of GDDR6 on a 256-bit bus, providing 608.0 GB/s of bandwidth with memory at 2375 MHz (19 Gbps effective). That is four times the capacity and more than double the bandwidth.

Compute resources also diverge. The RX 7700S has 2048 shading units, 128 TMUs, 64 ROPs, and 32 ray tracing cores. The Arc Pro B70 doubles most of these: 4096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. Despite the Intel card having twice the shading units and TMUs, its FP32 throughput is only 22.94 TFLOPS versus 20.48 TFLOPS for the AMD part. A similar pattern appears in FP16: 45.88 TFLOPS for Intel against 40.96 TFLOPS for AMD. Pixel rate favors Intel at 358.4 GPixel/s versus 160.0 GPixel/s, and texture rate is 716.8 GTexel/s versus 320.0 GTexel/s.

The power and physical profiles are opposite extremes. The RX 7700S is an integrated graphics package (IGP) with a 100 W TDP, no power connectors, and display outputs described as portable device dependent. The Arc Pro B70 is a dual-slot card with a 230 W TDP, a single 8-pin power connector, a suggested PSU of 550 W, and dimensions of 267 mm x 110 mm x 39 mm. It offers 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs. The RX 7700S uses PCIe 4.0 x16, while the Intel card uses PCIe 5.0 x16.

Release timing also differs. The RX 7700S launched on January 3, 2023; the Arc Pro B70 has a release date of March 25, 2026.

The Verdict

The recorded data separates these two GPUs into different usage categories. The RX 7700S is a 100 W integrated mobile part with 8 GB of memory and a 78th percentile ranking among all GPUs. Its average benchmark score of 33849 places it in the same performance band as older desktop cards: it sits 0.3% behind the AMD Radeon HD 7950, 0.4% behind the AMD Radeon RX 480, 0.5% ahead of the NVIDIA GeForce GTX 1060 5 GB, and 0.7% ahead of the NVIDIA RTX A5000. These deltas are all within one percentage point, meaning the RX 7700S effectively trades blows with that group of established GPUs.

The Arc Pro B70 has no benchmark entries in the database and no nearest rivals, so its average score is recorded as zero and its percentile sits at 50. The absence of measured results prevents any quantitative performance verdict for the Intel part. What the data does show is a card with a much larger memory pool, a wider bus, higher clocks, and a higher TDP envelope. It is a dual-slot add-in card with a 550 W suggested PSU, meaning it is designed for a full desktop or workstation chassis rather than a portable system.

For a portable platform where power draw is constrained, the RX 7700S is the only option that fits the IGP form factor within a 100 W envelope. For a professional workload that requires 32 GB of memory and 608.0 GB/s of bandwidth, the Arc Pro B70 provides the capacity and throughput that the AMD part cannot match. The Intel card also carries a launch MSRP of 949 USD, while the AMD card has no recorded launch price.

The choice depends on the platform and the workload. The data does not support a single winner because the benchmark coverage is incomplete on the Intel side. What is clear is that the RX 7700S has verified benchmark results in the database, while the Arc Pro B70 does not.

Head-to-Head Benchmarks

The head-to-head benchmark array in the database is empty, so there are no direct comparison runs between the RX 7700S and Arc Pro B70. The analysis must rely on the individual benchmark entries and the architectural figures.

The RX 7700S has three recorded benchmark results. In 3DMark Steel Nomad DX12 it scores 2185. In Geekbench OpenCL it scores 62983. In Geekbench Vulkan it scores 36380. These results feed into its average benchmark score of 33849. The nearest rival data gives context: the RX 7700S is 0.3% behind the HD 7950 (33951), 0.4% behind the RX 480 (33997), 0.5% ahead of the GTX 1060 5 GB (33694), and 0.7% ahead of the RTX A5000 (33622). Every delta is under one percent, so the RX 7700S sits in a tightly packed performance cluster.

The Arc Pro B70 has no benchmark entries at all. Its average score is listed as zero, and its percentile of 50 is the default midpoint. There are no nearest rivals recorded. This means the database contains no measured evidence that the Intel card outperforms the AMD card in any specific test, despite the large hardware advantages in the specification sheet.

Architectural wins for the Arc Pro B70 are visible in the raw figures. It delivers 22.94 TFLOPS of FP32 against 20.48 TFLOPS, a lead of 2.46 TFLOPS. Its FP16 output of 45.88 TFLOPS exceeds 40.96 TFLOPS by 4.92 TFLOPS. Pixel rate is more than double at 358.4 GPixel/s versus 160.0 GPixel/s. Texture rate is also more than double at 716.8 GTexel/s versus 320.0 GTexel/s. Memory bandwidth is 608.0 GB/s versus 288.0 GB/s, which is a 111% advantage. The Intel card has a higher boost clock by 300 MHz and a higher base clock by 780 MHz.

The RX 7700S wins on efficiency metrics. Its TDP of 100 W is less than half of the 230 W TDP of the Intel card. It has a smaller die at 204 mm² versus 368 mm². It requires no power connectors, while the Intel card needs a single 8-pin connector and a 550 W PSU. The AMD part is an IGP, meaning it can occupy a portable device slot, whereas the Intel card is dual-slot with a 267 mm length.

The data indicates that the Intel Arc Pro B70 is the stronger card on paper across compute, memory, and pixel throughput. The RX 7700S is the stronger card in the existing benchmark database, solely because it has results and the Intel card does not. Without measured scores for the Arc Pro B70, the database cannot confirm whether its architectural advantages translate into higher real-world performance. The RX 7700S also holds a higher percentile ranking at 78 versus 50, but that percentile is derived from its three benchmark scores, while the Intel card has none.

The empty head-to-head array means no single benchmark in the database shows one card defeating the other. The closest comparison available is the RX 7700S against its nearest rivals, all of which are within 0.7% of its average score. The Arc Pro B70 has no such comparison group, leaving its performance position undefined.
