AMD Instinct MI300X vs Intel Arc Graphics 64EU Comparison

Head-to-Head Benchmarks

The benchmark results for these two processors could not be more different in scope. The AMD Instinct MI300X delivers a Geekbench OpenCL score of 317994, placing it in the 100th percentile of all GPUs in the database. The Intel Arc Graphics 64EU, by contrast, records a 3DMark Steel Nomad DX12 score of 733, sitting at the 3rd percentile. These are not comparable test workloads, but the recorded data shows the MI300X operating in a completely different performance class.

The MI300X's nearest rivals provide essential context. It trails the NVIDIA B200 by 8%, with B200 averaging 345482. It also sits 5% behind the NVIDIA H200 NVL, which averages 334891. Against the NVIDIA L40S, the MI300X leads by 7.5%, and it beats the NVIDIA RTX 6000 Ada Generation by 10.7%. The MI300X holds a narrow gap to the top-tier accelerators and a clear lead over the mid-range professional cards.

The Intel Arc Graphics 64EU posts a 733 score, identical to the Intel Arc Graphics 32EU and 24EU, both at 733 with a 0% delta. It edges the AMD Radeon HD 6470M by 1.4% (723 score) but falls 2.4% behind the NVIDIA GeForce GT 415M (751 score). The data indicates that the 64EU integrated graphics performance is essentially flat across the low-end Intel lineup, with no meaningful differentiation between the 24EU, 32EU, and 64EU configurations in this particular test.

The absolute performance gap is stark. The MI300X produces 81.72 TFLOPS of FP32 compute, while the Arc 64EU delivers 1.946 TFLOPS. That is a 42x difference in raw floating-point throughput, directly reflected in the benchmark disparity. The MI300X achieves 2,553.6 GTexel/s texture rate against the Arc's 60.80 GTexel/s. Pixel rate also diverges: the MI300X reports 0 MPixel/s due to its compute-only design, while the Arc 64EU manages 30.40 GPixel/s.

Where Each One Wins

The AMD Instinct MI300X wins in every compute-heavy metric recorded. Its 19456 shading units dwarf the Arc's 512. The 1216 texture mapping units compare to 32 on the Arc. Memory bandwidth shows a 5.32 TB/s figure on the MI300X versus "System Dependent" bandwidth on the Arc, which relies on shared system memory. The MI300X also carries 192 GB of HBM3 across an 8192-bit bus, while the Arc uses system shared memory with no dedicated allocation.

The Intel Arc Graphics 64EU holds advantages in specific architectural features. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI300X lists N/A for all three API categories, reflecting its compute-only orientation with no display or graphics output capabilities. The Arc also has 16 ROPs, enabling rasterization output, whereas the MI300X has 0 ROPs and a pixel rate of 0 MPixel/s.

For use-case segmentation, the MI300X targets data center and HPC workloads requiring massive parallel compute and memory capacity. Its FP16 performance matches FP32 at 81.72 TFLOPS (1:1 ratio), indicating no throughput penalty for reduced precision. The Arc 64EU delivers 3.891 TFLOPS FP16 (2:1 ratio), meaning half precision runs at double the FP32 rate. This makes the Arc more efficient for mixed-precision graphics workloads, though at a vastly smaller absolute scale.

The Arc 64EU's power envelope of 65 W TDP allows integration into desktop processors as an IGP. The MI300X requires 750 W TDP with a suggested 1150 W PSU, as an OAM module with no power connectors listed. The Arc uses a Ring Bus interface, while the MI300X connects via PCIe 5.0 x16. These are fundamentally different product categories: one is an accelerator module, the other is an integrated graphics processor.

Architecture Differences

The MI300X uses the CDNA 3.0 architecture on TSMC's 5 nm process, with the chip named Aqua Vanjaram. It contains 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4M per mm². The Arc 64EU employs Xe-LPG architecture on TSMC's 3 nm node, with the Arrow Lake-S chip containing 17,800 million transistors across a 243 mm² die, for a density of 73.3M per mm². The MI300X uses a larger, denser chip with 8.6x more transistors.

Clock behavior differs significantly. The MI300X runs at a 1000 MHz base and 2100 MHz boost, while the Arc operates at 300 MHz base and 1900 MHz boost. The MI300X's memory clock is 1300 MHz with 5.2 Gbps effective data rate. The Arc's memory clock is "System Shared," meaning it depends on the host system's memory configuration.

The MI300X belongs to the Instinct (MIx) generation with a release date of 2023-12-05. Its predecessor is Radeon Instinct. The Arc 64EU is part of the Arc Graphics (Arrow Lake) generation, released 2024-10-23, with HD Graphics as its predecessor. The Arc's production status is listed as "Active," while the MI300X's production status is not specified in the database.

The MI300X has no display outputs, no power connectors, and an OAM Module slot width. The Arc has motherboard-dependent display outputs and an IGP slot width. The MI300X's API support is entirely absent (N/A for DirectX, OpenGL, Vulkan), reinforcing its role as a compute accelerator without graphics rendering capabilities. The Arc supports the full modern graphics API stack.

The Verdict

The data positions these two products at opposite ends of the GPU performance spectrum. The AMD Instinct MI300X is a data center accelerator with a 100th percentile ranking, 192 GB of HBM3 memory, and 81.72 TFLOPS of FP32 compute. It competes directly with NVIDIA's top accelerators, trailing the B200 by 8% and H200 NVL by 5%, while leading the L40S and RTX 6000 Ada by 7.5% and 10.7%, respectively. For workloads requiring massive memory capacity and compute throughput, the MI300X is the clear choice.

The Intel Arc Graphics 64EU serves an entirely different purpose. At the 3rd percentile with a 733 score, it matches the performance of Intel's 32EU and 24EU variants exactly, indicating that this integrated graphics solution offers no measurable advantage over lower EU counts in the recorded 3DMark test. Its nearest rivals are legacy mobile GPUs from over a decade ago, with performance within 2.4% of the GeForce GT 415M.

The MI300X's CDNA 3.0 architecture with 19456 shading units and 1216 TMUs delivers compute density that the Arc's 512 shading units and 32 TMUs cannot approach. The MI300X also holds a 42x FP32 advantage and a 42x texture rate advantage. The Arc counters with full graphics API support, 16 ROPs, and a 30.40 GPixel/s pixel rate, features absent from the MI300X entirely.

Buyers selecting between these should base the decision on workload type. The MI300X serves AI training, scientific simulation, and high-performance computing with its 192 GB memory pool and 5.32 TB/s bandwidth. The Arc 64EU provides basic integrated graphics for desktop systems, with modern API support but performance limited to the low end of the database. The production status of the MI300X is not recorded, while the Arc 64EU is listed as Active, suggesting ongoing availability for the latter.
