AMD Instinct MI308X vs AMD Radeon 880M Comparison

Head-to-Head Benchmarks

The recorded data shows a stark asymmetry between these two AMD parts. The AMD Instinct MI308X has no benchmark entries in the database, meaning its average benchmark score is recorded as zero with a percentile ranking of 50. In contrast, the AMD Radeon 880M carries a full suite of ten benchmark results, with an average score of 8436 and a percentile ranking of 43. The head-to-head benchmark table is empty, and the win tally shows zero victories for each side. This absence of comparative data dictates that any performance assessment must rely on architectural specifications and the Radeon 880M's standalone results.

The Radeon 880M's benchmark scores reveal a clear pattern. Its strongest showing is in Geekbench Vulkan, where it records a score of 40006, followed by Geekbench OpenCL at 31285. These compute-oriented tests dwarf its DirectX results, indicating a pronounced strength in general-purpose GPU workloads. The Passmark suite tells a more granular story: Passmark G3D scores 7615, while Passmark GPU Compute reaches 3719. Legacy DirectX tests show lower numbers, with DirectX 9 at 97, DirectX 11 at 73, DirectX 12 at 32, and DirectX 10 at 31. The 2D graphics score sits at 969.

Relative to its nearest rivals, the Radeon 880M's position is narrow. It trails the NVIDIA GeForce MX330 by 0.3 percent and the AMD Radeon HD 8870M by 0.3 percent, while leading the NVIDIA GeForce GTX 675MX by 0.1 percent and the AMD Radeon R9 M375X by 1.3 percent. These deltas are marginal, within a single percentile point for three of the four comparisons. The data indicates that the Radeon 880M occupies a performance tier that is essentially interchangeable with these older discrete mobile GPUs, despite being an integrated processor.

Architecture Differences

The two chips diverge fundamentally in their underlying design. The AMD Instinct MI308X uses the Aqua Vanjaram chip built on CDNA 3.0 architecture, manufactured on a 5 nm process at TSMC. It packs 153,000 million transistors into a die size of 1017 mm², yielding a transistor density of 150.4 million per square millimeter. The AMD Radeon 880M, conversely, uses the Strix Point chip with RDNA 3.5 architecture, fabricated on a 4 nm process, also at TSMC. Its transistor count is 34,000 million on a die of 233 mm², with a density of 145.9 million per square millimeter. The MI308X is a massive compute accelerator; the Radeon 880M is a compact integrated graphics processor.

The compute resources reflect this divide. The MI308X contains 19456 shading units, 1216 texture mapping units, and zero raster operation units, producing a pixel rate of 0 MPixel/s and a texture rate of 2553.6 GTexel/s. Its floating-point throughput reaches 81.72 TFLOPS for both FP32 and FP16, the latter at a 1:1 ratio. The Radeon 880M has 768 shading units, 48 TMUs, 16 ROPs, and 12 ray tracing cores. Its pixel rate is 46.40 GPixel/s, texture rate is 139.2 GTexel/s, and FP32 and FP16 both sit at 4.454 TFLOPS. The MI308X delivers roughly 18.3 times the FP32 throughput of the Radeon 880M, a gap that underscores their divergent roles.

Memory systems could not be more different. The MI308X uses 192 GB of HBM3 memory on an 8192-bit bus, with a bandwidth of 5.32 TB/s and a memory clock of 1300 MHz (5.2 Gbps effective). The Radeon 880M uses system shared memory, with its bus width, type, and bandwidth all listed as system dependent. The MI308X's memory bandwidth is fixed and enormous; the Radeon 880M's is variable and constrained by the host system.

Clock speeds also differ sharply. The MI308X has a base clock of 1000 MHz and a boost clock of 2100 MHz. The Radeon 880M runs at 400 MHz base and 2900 MHz boost. The higher boost on the Radeon 880M reflects its lower transistor count and smaller die, which permit higher frequencies within a 15 W power envelope. The MI308X, by contrast, draws 750 W and requires a suggested power supply of 1150 W, while the Radeon 880M operates at 15 W with no suggested PSU listed.

Where Each One Wins

The MI308X wins in raw compute capacity. Its FP32 rating of 81.72 TFLOPS is a server-class figure, and its 5.32 TB/s memory bandwidth is orders of magnitude beyond any shared-memory solution. The 192 GB HBM3 pool allows it to hold massive datasets entirely on-board, eliminating the need for constant host transfers. Its texture rate of 2553.6 GTexel/s indicates extreme fill-rate capability for data-heavy workloads. This part is built for dense matrix operations, large-scale inference, and scientific simulation where memory capacity and bandwidth are the primary constraints.

The Radeon 880M wins in architectural completeness for graphics. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI308X lists N/A for all three APIs. The Radeon 880M includes 12 ray tracing cores, a feature entirely absent from the MI308X's specification. Its pixel rate of 46.40 GPixel/s and its 16 ROPs enable actual rasterization output, whereas the MI308X has zero ROPs and a 0 MPixel/s pixel rate. The Radeon 880M is a functional display adapter with portable-device-dependent outputs; the MI308X has no display outputs at all.

The Radeon 880M also wins on efficiency and integration. Its 15 W TDP allows deployment in laptops and compact devices, while the MI308X's 750 W TDP demands a server chassis with substantial cooling and power delivery. The Radeon 880M's release date of July 2024 places it as a newer product than the MI308X's December 2023 launch. The Radeon 880M's production status is listed as Active, while the MI308X carries no production status, suggesting the IGP remains in current production while the accelerator's status is unrecorded.

The Verdict

The data indicates that these two products are not competitors but complementary extremes of AMD's portfolio. The MI308X is a datacenter compute accelerator with no graphics APIs, no display outputs, and no benchmarks recorded. Its performance profile must be inferred from specifications: 81.72 TFLOPS FP32, 192 GB HBM3, and a 5.32 TB/s memory bandwidth. It targets workloads where graphics output is irrelevant and compute density is paramount. The Radeon 880M is an integrated graphics processor for mobile systems, with full DirectX, OpenGL, and Vulkan support, ray tracing hardware, and a benchmark suite confirming its position near the performance of older mid-range mobile GPUs.

For a user needing a display-capable GPU with modern API support and ray tracing, the Radeon 880M is the only viable choice between these two. Its benchmark scores, while modest relative to discrete desktop parts, show solid compute performance in Geekbench Vulkan and OpenCL. For a user needing massive on-board memory and extreme FP32 throughput for non-graphics workloads, the MI308X is the clear selection, provided the system can supply 750 W and handle an OAM module with no display outputs.

The verdict from the recorded data is unambiguous: choose the MI308X for compute acceleration without any rendering requirements, and choose the Radeon 880M for any task requiring a visible output, modern graphics APIs, or low power consumption. The two parts share a manufacturer and a foundry, but their architectures, memory systems, power envelopes, and intended applications are entirely distinct.
