AMD Radeon RX 7800M vs Intel Arc Pro B70 Comparison

Head-to-Head Benchmarks

The AMD Radeon RX 7800M and Intel Arc Pro B70 occupy different positions in the database's recorded performance hierarchy. The AMD part, built on the Navi 32 chip with RDNA 3.0 architecture, shows a substantial catalog of benchmark results across DirectX, OpenCL, and Vulkan workloads. The Intel Arc Pro B70, using the BMG-G31 chip with Xe2-HPG architecture, currently has no recorded benchmark scores in the database, which places its average benchmark score at zero and its percentile against all GPUs at 50.

The AMD Radeon RX 7800M delivers a 3DMark Steel Nomad DX12 score of 2994. In Geekbench compute tests, it records 120778 in OpenCL and 126668 in Vulkan. Passmark results show 17613 in the G3D test, 9342 in GPU compute, 892 in G2D, and legacy DirectX scores of 176 for DX11, 174 for DX9, 99 for DX10, and 89 for DX12. Its average benchmark score across all recorded tests is 27883, placing it in the 73rd percentile of all GPUs tracked by the database.

The Intel Arc Pro B70 has no benchmark entries, meaning its average score is zero and its percentile sits at 50. The database records no head-to-head benchmark comparisons between these two parts, and the win counts stand at zero for each. This does not indicate parity; it indicates an absence of measured data for the Intel SKU. The AMD part's nearest rivals, all with similar average scores, include the AMD Radeon Pro Vega 20 at 27839 (a 0.2% delta), the AMD Radeon Pro W5500X at 27973 (-0.3% delta), the NVIDIA GeForce GTX 980 Ti at 28020 (-0.5% delta), and the AMD FirePro S7150 at 28117 (-0.8% delta). These margins are tightly clustered, confirming that the RX 7800M sits within a narrow performance band among workstation and older flagship desktop parts.

Where Each One Wins

The AMD Radeon RX 7800M wins in every category where recorded measurements exist, solely because the Intel Arc Pro B70 has no benchmark data in the database. The RX 7800M's strengths are measurable across modern APIs: its 3DMark Steel Nomad DX12 score of 2994 reflects current-generation DirectX 12 Ultimate workloads, and its Geekbench Vulkan result of 126668 confirms strong cross-platform compute and graphics performance. Passmark G3D at 17613 and GPU compute at 9342 further establish its capability in rasterized gaming and general-purpose compute tasks.

The Intel Arc Pro B70, despite lacking benchmark scores, presents a hardware configuration that indicates a different intended workload profile. It offers 32 GB of GDDR6 memory on a 256-bit bus with 608.0 GB/s bandwidth, compared to the RX 7800M's 12 GB on a 192-bit bus with 432.0 GB/s. The Intel part's FP16 throughput of 45.88 TFLOPS (2:1 ratio) exceeds its FP32 output of 22.94 TFLOPS, suggesting a design optimized for mixed-precision workloads such as AI inference and certain scientific computations. The AMD part delivers FP32 at 35.87 TFLOPS and FP16 at the same 35.87 TFLOPS (1:1 ratio), indicating a more balanced approach.

Where the AMD card wins in measured performance, the Intel card wins in memory capacity and bandwidth. The 32 GB frame buffer is 2.67 times larger than the AMD's 12 GB, and the 608.0 GB/s bandwidth is 40.7% higher than 432.0 GB/s. For large dataset processing, rendering high-resolution textures, or compute tasks that exceed 12 GB, the Intel part's memory subsystem is the deciding factor. The RX 7800M's 73rd percentile ranking versus the Intel part's 50th percentile, however, reflects the current database state where only one part has actual scores.

Specification Differences

The two GPUs differ across nearly every major specification category. The AMD Radeon RX 7800M uses the Navi 32 chip with 28,100 million transistors on a 346 mm² die, while the Intel Arc Pro B70 uses the BMG-G31 chip with an unknown transistor count on a 368 mm² die. Both use a 5 nm process from TSMC. The Intel die is 6.4% larger by area.

Clock speeds show a significant difference. The AMD part has a base clock of 1295 MHz, a boost of 2335 MHz, and a game clock of 2145 MHz. The Intel part runs a base clock of 2280 MHz and a boost of 2800 MHz, with no game clock specified. The Intel boost clock is 19.9% higher than the AMD boost clock. Memory clocks also differ: 2250 MHz (18 Gbps effective) for AMD versus 2375 MHz (19 Gbps effective) for Intel.

Memory configuration diverges sharply. The AMD card provides 12 GB GDDR6 on a 192-bit bus, yielding 432.0 GB/s. The Intel card provides 32 GB GDDR6 on a 256-bit bus, yielding 608.0 GB/s. The Intel memory bus is 33.3% wider, and its bandwidth is 40.7% higher.

Compute unit counts favor Intel in raw numbers: 4096 shading units, 256 TMUs, and 128 ROPs versus AMD's 3840 shading units, 240 TMUs, and 96 ROPs. Ray tracing cores differ in count but not directly comparable architecture: AMD has 60 RT cores, Intel has 32. Neither has tensor cores listed. The Intel part's FP16 output of 45.88 TFLOPS (2:1 ratio) exceeds its FP32, while AMD's FP16 matches its FP32 at 35.87 TFLOPS (1:1 ratio).

Power and physical specifications differ. The AMD part is rated at 180 W TDP, is an IGP (integrated graphics processor) with no power connectors and no suggested PSU. The Intel part is rated at 230 W TDP, is a dual-slot card requiring a single 8-pin power connector and a 550 W suggested PSU. The Intel card measures 267 mm in length, 110 mm in height, and 39 mm in width. The AMD card has no recorded dimensions.

Bus interface and display outputs also differ. AMD uses PCIe 4.0 x16; Intel uses PCIe 5.0 x16. AMD's display outputs are listed as "Portable Device Dependent" (consistent with an IGP), while Intel provides 1x HDMI 2.1a and 3x DisplayPort 2.1. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Architecture Differences

The AMD Radeon RX 7800M belongs to the Radeon RX 7000 series, uses RDNA 3.0 architecture, and carries the codename "Wheat Nas." Its generation is Navi Mobile (RX 7000M), and its predecessor is Polaris Mobile. It was released on September 10, 2024, and remains in active production. The architecture is built around a 5 nm TSMC process with 28,100 million transistors on a 346 mm² die, giving a transistor density of 81.2 million transistors per square millimeter.

The Intel Arc Pro B70 belongs to the Battlemage (Pro Series) generation, uses Xe2-HPG architecture, and has no recorded codename. Its chip is BMG-G31, also fabricated on a 5 nm TSMC process, with an unknown transistor count on a 368 mm² die. No transistor density is listed. Its release date is March 25, 2026, and its production status is not recorded. No predecessor or successor is listed.

The architectural design philosophies diverge in compute and memory strategy. AMD's RDNA 3.0 uses a 1:1 FP16 to FP32 ratio, meaning the same execution units handle both precisions at equal throughput. Intel's Xe2-HPG uses a 2:1 ratio, where FP16 throughput doubles FP32, indicating dedicated or accelerated half-precision paths. This makes the Intel architecture more aligned with mixed-precision workloads, while AMD's balanced approach suits general graphics and FP32-centric compute.

Memory architecture differences reinforce this split. The AMD part's 12 GB frame buffer with 432.0 GB/s suits mainstream gaming and portable device integration, given its IGP form factor and 180 W TDP. The Intel part's 32 GB frame buffer with 608.0 GB/s, dual-slot design, and 230 W TDP targets professional visualization, large model inference, and high-resolution rendering where memory capacity is the limiting factor. The PCIe 5.0 x16 interface on the Intel card provides twice the bus bandwidth of the AMD card's PCIe 4.0 x16, which matters for data transfer to and from the host system.

Ray tracing and rendering hardware also differ in configuration. The AMD card has 60 ray tracing cores; the Intel card has 32. Both support DirectX 12 Ultimate, implying hardware-accelerated ray tracing, mesh shaders, and variable rate shading. The Intel card's higher ROP count (128 versus 96) and TMU count (256 versus 240) give it higher theoretical pixel and texture throughput, as recorded in the 358.4 GPixel/s and 716.8 GTexel/s figures. The AMD card counters with higher FP32 throughput at 35.87 TFLOPS, which matters for compute-heavy graphics workloads.

The launch MSRP for the Intel Arc Pro B70 is 949 USD, stated once here as recorded. The AMD Radeon RX 7800M has no launch MSRP in the database. The database's current state shows a clear asymmetry: one fully measured mobile GPU with a 73rd percentile standing, and one unmeasured professional GPU with a 50th percentile placeholder. Until the Intel Arc Pro B70 receives benchmark entries, any direct performance comparison relies on architectural inference rather than measured results.
