The Verdict

The data shows two entirely different product categories. The AMD Instinct MI308X is a compute accelerator with 19456 shading units, 1216 texture mapping units, and 192 GB of HBM3 memory. It delivers 81.72 TFLOPS of FP32 performance and 81.72 TFLOPS of FP16 performance at a 1:1 ratio. Its 5 nm process node from TSMC packs 153,000 million transistors onto a 1017 mm² die. The Intel Arc B370 is an integrated graphics processor on a 3 nm Intel node with 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. It delivers 6.144 TFLOPS FP32 and 12.29 TFLOPS FP16 at a 2:1 ratio.

The benchmark data favors the Intel Arc B370 in terms of recorded results, as it has a measurable 3DMark Steel Nomad DX12 score of 1184. The AMD part has no scores in the database, so direct performance comparisons rely on architectural specifications. The Intel Arc B370's nearest rivals include the ATI Mobility Radeon HD 5570 at 1186, the ATI Radeon HD 5770 at 1190, the AMD Radeon HD 7650M at 1192, and the AMD FirePro M2000 at 1168. The Arc B370 sits within 0.7% of three of these parts and 1.4% above the FirePro M2000.

The AMD Instinct MI308X targets a different workload entirely. Its 5.32 TB/s memory bandwidth and 2,553.6 GTexel/s texture rate indicate a high-throughput compute design. The Intel Arc B370, with its 48.00 GPixel/s pixel rate and 96.00 GTexel/s texture rate, operates at a much smaller scale. The choice between these two depends on the application: the MI308X serves compute-heavy environments, while the Arc B370 serves portable devices with integrated graphics needs.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark comparisons between the AMD Instinct MI308X and the Intel Arc B370. Wins are zero for both sides in the head-to-head table. The only available benchmark score belongs to the Intel Arc B370, which records 1184 in 3DMark Steel Nomad DX12. This places the part in the 5th percentile of all GPUs.

The AMD Instinct MI308X has an average benchmark score of 0 and occupies the 50th percentile, but no specific tests are listed. The absence of data means no quantitative comparison can be made from benchmark runs. Instead, the specification sheet provides the only basis for differentiation.

In FP32 compute, the AMD part delivers 81.72 TFLOPS versus 6.144 TFLOPS for the Intel part. That is a 13.3x difference in raw floating-point throughput. In FP16, the AMD part again delivers 81.72 TFLOPS, while the Intel part delivers 12.29 TFLOPS, a 6.6x difference. The Intel Arc B370 achieves its FP16 number through a 2:1 ratio, effectively doubling its FP32 rate, while the AMD part runs FP16 at the same rate as FP32.

Texture throughput shows a similar gap. The AMD Instinct MI308X processes 2,553.6 GTexel/s, while the Intel Arc B370 processes 96.00 GTexel/s. Pixel throughput is reversed in nature: the AMD part has 0 ROPs and records 0 MPixel/s, while the Intel part has 20 ROPs and delivers 48.00 GPixel/s. This reflects the AMD accelerator's design, which omits traditional rasterization hardware.

In memory bandwidth, the AMD part delivers 5.32 TB/s from HBM3 on an 8192-bit bus. The Intel part relies on system shared memory with system dependent bandwidth. The AMD part's memory clock runs at 1300 MHz with 5.2 Gbps effective data rate, while the Intel part has no dedicated memory clock.

Specification Differences

The two products differ across nearly every measurable specification. The AMD Instinct MI308X uses a 5 nm TSMC process, while the Intel Arc B370 uses a 3 nm Intel process. The AMD chip, codenamed Aqua Vanjaram, has 153,000 million transistors on a 1017 mm² die. The Intel chip, codenamed Panther Lake, has unknown transistor counts and die size.

Shading units number 19456 on the AMD part versus 1280 on the Intel part. Texture mapping units number 1216 versus 40. Raster operations pipelines number 0 on the AMD part versus 20 on the Intel part. The Intel part includes 10 ray tracing cores, while the AMD part lists none. The AMD part has no display outputs, while the Intel part supports portable device dependent outputs.

Memory configurations are fundamentally different. The AMD part uses 192 GB of HBM3 with an 8192-bit bus and 5.32 TB/s bandwidth. The Intel part uses system shared memory with system dependent bandwidth. The AMD part's memory runs at 1300 MHz with 5.2 Gbps effective, while the Intel part has no dedicated memory clock.

Clock speeds differ in base and boost. The AMD part runs at 1000 MHz base and 2100 MHz boost. The Intel part runs at 300 MHz base and 2400 MHz boost. The Intel part has a higher boost clock by 300 MHz, but the AMD part has a higher base clock by 700 MHz.

Power requirements diverge sharply. The AMD part draws 750 W TDP and suggests a 1150 W power supply. The Intel part draws 25 W TDP and lists no suggested PSU. The AMD part uses an OAM module slot width with PCIe 5.0 x16 bus interface. The Intel part uses an IGP slot width with IGP bus interface. Neither uses power connectors.

API support differs completely. The AMD part lists N/A for DirectX, OpenGL, and Vulkan. The Intel part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The AMD part has no launch MSRP recorded. The Intel part also has no launch MSRP recorded.

Architecture Differences

The AMD Instinct MI308X uses the CDNA 3.0 architecture, designed for compute acceleration. The Intel Arc B370 uses the Xe3-LPG architecture, designed for integrated graphics in mobile processors. The AMD part belongs to the Instinct (MIx) generation, while the Intel part belongs to the Arc Graphics-M (Panther Lake) generation.

The AMD chip, Aqua Vanjaram, is built on TSMC's 5 nm node. The Intel chip, Panther Lake, is built on Intel's 3 nm node. The AMD design prioritizes memory bandwidth and compute density, evidenced by its 8192-bit bus and 5.32 TB/s throughput. The Intel design prioritizes power efficiency, evidenced by its 25 W TDP.

Cache and core configurations reflect the different targets. The AMD part carries 19456 shading units and 1216 TMUs, with no ROPs and no ray tracing cores. The Intel part carries 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. The presence of ROPs and ray tracing hardware on the Intel part indicates a graphics-oriented pipeline, while the AMD part's lack of these units confirms a compute-only design.

The AMD part supports no graphics APIs, listing N/A for DirectX, OpenGL, and Vulkan. The Intel part supports modern graphics APIs including DirectX 12 Ultimate and Vulkan 1.4. This aligns with the AMD part's role as an accelerator with no display outputs, versus the Intel part's role as an integrated GPU with portable device outputs.

Memory architecture separates the two further. The AMD part uses dedicated HBM3 memory with fixed bandwidth. The Intel part uses system shared memory, making its bandwidth dependent on the host system. The AMD part's memory clock is fixed at 1300 MHz with a 5.2 Gbps effective rate. The Intel part has no memory clock because it shares system memory.

FP16 processing differs in approach. The AMD part achieves 81.72 TFLOPS FP16 at a 1:1 ratio with FP32. The Intel part achieves 12.29 TFLOPS FP16 at a 2:1 ratio, meaning it processes two FP16 operations per FP32 operation. This indicates different throughput strategies for mixed-precision workloads.

The Intel Arc B370 is marked as an active production product with a release date of January 26, 2026. The AMD Instinct MI308X has no production status listed and was released on December 5, 2023. The AMD part's predecessor is listed as Radeon Instinct, while the Intel part has no predecessor recorded.
