AMD Instinct MI300A vs Intel Arc B370 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparisons between the AMD Instinct MI300A and the Intel Arc B370. The head-to-head benchmark results list is empty, and neither product records any wins in shared testing. This absence of overlap is not surprising given their entirely different market positions: the MI300A is a data center accelerator with no display outputs, while the Arc B370 is an integrated graphics processor designed for portable devices.

The only benchmark score in the database belongs to the Intel Arc B370. Its 3DMark Steel Nomad DX12 result is 1184 points. This places the Arc B370 at the 5th percentile among all GPUs in the database. The nearest rivals provide context: the ATI Mobility Radeon HD 5570 scores 1186 points, which is 0.2% higher than the Arc B370. The ATI Radeon HD 5770 scores 1190 points, 0.5% higher. The AMD Radeon HD 7650M scores 1192 points, 0.7% higher. The AMD FirePro M2000 scores 1168 points, which is 1.4% lower than the Arc B370. These narrow margins show the Arc B370 sits in a tightly clustered performance band with legacy mobile and entry-level desktop parts from over a decade ago.

The AMD Instinct MI300A has no benchmark records in the database. Its average benchmark score is zero, and its percentile versus all GPUs is 50, which is a default placeholder rather than a measured result. Consequently, no comparative performance statements can be made from measured data. The MI300A's theoretical compute figures are recorded, but they are not tied to any benchmark test.

Because the head-to-head field is empty, the data cannot indicate which product wins in direct competition. The Arc B370 has one measurable data point, and the MI300A has none. The analysis must rely on architectural specifications and the single recorded test result for the Intel part.

Where Each One Wins

The Intel Arc B370 wins in the only measurable benchmark category present in the database. Its 3DMark Steel Nomad DX12 score of 1184 demonstrates functional DirectX 12 Ultimate support with the 12_2 feature level, OpenGL 4.6 support, and Vulkan 1.4 support. The Arc B370 also delivers a pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s. Its FP32 throughput is 6.144 TFLOPS, and its FP16 throughput is 12.29 TFLOPS with a 2:1 ratio. These figures indicate the Arc B370 is capable of running modern graphics workloads, albeit at a performance level comparable to the ATI Mobility Radeon HD 5570 and ATI Radeon HD 5770, as the nearest rival deltas show.

The AMD Instinct MI300A wins in raw compute capacity, based on recorded specifications rather than benchmark results. Its FP32 throughput is 61.29 TFLOPS, more than ten times the Arc B370's 6.144 TFLOPS. The texture rate is 1,915.2 GTexel/s, roughly twenty times the Arc B370's 96.00 GTexel/s. The MI300A has 14,592 shading units versus 1,280 for the Arc B370. It has 912 texture mapping units versus 40. The MI300A uses 128 GB of HBM3 memory with an 8192-bit bus and 5.32 TB/s bandwidth, while the Arc B370 uses system shared memory with system dependent bandwidth. The MI300A has no display outputs, so it cannot render to a screen; the Arc B370's display outputs are portable device dependent, meaning it is intended for integrated use in laptops or similar hardware.

The data shows the MI300A is designed for compute acceleration in server environments, not for graphics rendering. Its pixel rate is recorded as 0 MPixel/s, and its ROP count is zero. The Arc B370 has 20 ROPs and a 48.00 GPixel/s pixel rate, confirming it is a graphics-oriented part. The wins split along these lines: the Arc B370 offers actual graphics pipeline functionality and a measurable DirectX 12 benchmark result, while the MI300A offers vastly larger raw compute resources with no graphics output capability.

Architecture Differences

The AMD Instinct MI300A uses the Aqua Vanjaram chip built on CDNA 3.0 architecture, fabricated on a 5 nm process at TSMC. It contains 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4 million transistors per square millimeter. The base clock is 1000 MHz with a boost clock of 2100 MHz. Memory runs at 1300 MHz with 5.2 Gbps effective speed. The MI300A has 14,592 shading units, 912 TMUs, and zero ROPs. It has no ray tracing cores and no tensor cores recorded. The FP32 throughput is 61.29 TFLOPS. Power draw is 750 W TDP with a suggested power supply of 1150 W. The slot width is OAM Module, and the bus interface is PCIe 5.0 x16. It uses no power connectors and provides no display outputs. DirectX, OpenGL, and Vulkan APIs are all listed as N/A. The release date is December 5, 2023, and its predecessor is Radeon Instinct.

The Intel Arc B370 uses the Panther Lake chip built on Xe3-LPG architecture, fabricated on a 3 nm process at Intel. Transistor count and die size are unknown. The base clock is 300 MHz with a boost clock of 2400 MHz. Memory is system shared, meaning size, type, bus width, and bandwidth all depend on the host system. The Arc B370 has 1,280 shading units, 40 TMUs, and 20 ROPs. It has 10 ray tracing cores. FP32 throughput is 6.144 TFLOPS, and FP16 throughput is 12.29 TFLOPS with a 2:1 ratio. Pixel rate is 48.00 GPixel/s, and texture rate is 96.00 GTexel/s. Power draw is 25 W TDP, and the slot width is IGP. The bus interface is IGP, and it uses no power connectors. Display outputs are portable device dependent. DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 are supported. The production status is active, and the release date is January 26, 2026.

The process nodes differ: 5 nm for the MI300A versus 3 nm for the Arc B370. The foundries differ: TSMC versus Intel. The architectures differ fundamentally: CDNA 3.0 is a compute-oriented design with no ROPs or graphics API support, while Xe3-LPG is a low-power graphics architecture with full modern API coverage including ray tracing cores. The MI300A has a massive memory subsystem with 128 GB of HBM3 and 5.32 TB/s bandwidth, whereas the Arc B370 relies entirely on system memory. The MI300A has no ray tracing hardware, while the Arc B370 includes 10 RT cores.

Clock behavior also differs sharply. The MI300A idles at 1000 MHz and boosts to 2100 MHz, a relatively narrow range. The Arc B370 idles at 300 MHz and boosts to 2400 MHz, a much wider dynamic range suited to power saving in portable devices. The MI300A's 750 W TDP versus the Arc B370's 25 W TDP represents a 30x difference in power envelope, reflecting their distinct deployment scenarios.
