AMD Radeon 8065S vs AMD Radeon Instinct MI300X Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark entries for the AMD Radeon 8065S versus the AMD Radeon Instinct MI300X. Both entries list an average benchmark score of zero and a percentile rank of 50 among all GPUs, with no nearest rivals defined. Consequently, direct performance comparisons from measured workloads are unavailable.

The absence of benchmark data does not imply equivalence. The two accelerators occupy entirely different segments of the AMD product stack, and their architectural specifications indicate vastly different computational profiles. The Radeon 8065S is a mobile integrated graphics processor built on the RDNA 3.5 architecture, while the Radeon Instinct MI300X is a data center compute accelerator based on CDNA 3.0. Without measured scores, the analysis must rely on the recorded hardware characteristics to establish expected performance relationships.

The most significant numerical gap appears in raw compute throughput. The MI300X delivers 81.72 TFLOPS of FP32 performance, which is 5.32 times the 15.36 TFLOPS of the 8065S. For FP16 workloads, the divergence becomes extreme: the MI300X reaches 653.7 TFLOPS under its 8:1 ratio, while the 8065S produces 15.36 TFLOPS at a 1:1 ratio. That represents a 42.6-fold difference in peak half-precision throughput.

Memory resources show a similarly dramatic separation. The MI300X carries 192 GB of HBM3 memory across an 8192-bit bus, yielding 10.3 TB/s of bandwidth. The 8065S uses system shared memory with bandwidth described as system dependent, meaning its effective memory throughput cannot be quantified from the database entries alone. The MI300X also operates with a 2525 MHz memory clock at 10.1 Gbps effective, whereas the 8065S memory clock is listed simply as system shared.

Texture processing rates favor the MI300X by a factor of 5.32, matching the FP32 ratio: 2,553.6 GTexel/s versus 480.0 GTexel/s. The pixel rate comparison is inverted in a meaningful way. The MI300X records 0 MPixel/s because it has no ROPs and no display outputs, while the 8065S produces 192.0 GPixel/s through its 64 ROPs. This reflects their divergent purposes: rendering frames versus accelerating compute workloads.

Clock speeds differ as well. The 8065S runs at a 1295 MHz base frequency and boosts to 3000 MHz. The MI300X operates at 1000 MHz base and 2100 MHz boost. The mobile part therefore runs 29.5% higher at base and 42.9% higher at boost, but the data center part compensates with 7.6 times more shading units (19,456 versus 2,560) and 7.6 times more TMUs (1,216 versus 160).

Where Each One Wins

The Radeon 8065S wins in scenarios involving display output and conventional graphics rendering. It includes 40 ray tracing cores, support for DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI300X lists no ray tracing cores, no DirectX support, no OpenGL support, and no Vulkan support. The 8065S also provides 64 ROPs and a 192.0 GPixel/s pixel fill rate, enabling rasterization workloads that the MI300X cannot handle at all given its 0 MPixel/s pixel rate and lack of display connectors.

The MI300X wins decisively in compute-heavy data center tasks. Its 192 GB of HBM3 memory with 10.3 TB/s bandwidth accommodates large models and datasets that would far exceed the system shared memory available to the 8065S. The 8:1 FP16 ratio indicates specialized matrix math acceleration, which suits AI training and inference workloads. The 153,000 million transistor count on a 1017 mm² die, compared to an unknown transistor count on the 308 mm² 8065S die, further indicates the MI300X is engineered for massive parallel computation.

Power and physical configuration also separate their use cases. The 8065S draws 55 W and is an integrated graphics processor with no power connectors, fitting into portable devices. The MI300X consumes 750 W, requires a suggested PSU of 1150 W, and mounts as an OAM module with no display outputs. The 8065S uses a 4 nm process from TSMC, while the MI300X uses a 5 nm process, giving the mobile part a density advantage per square millimeter despite the smaller absolute die.

The 8065S has a production status of active and a release date of December 31, 2025. The MI300X lists a null production status and a release date of December 5, 2023. The 8065S succeeds Polaris Mobile, while the MI300X succeeds FirePro Data Center. Neither entry has a successor recorded.

The Verdict

The data indicates these products target mutually exclusive workloads. The Radeon 8065S is designed for portable systems requiring integrated graphics with modern API support, ray tracing capability, and low power consumption. The Radeon Instinct MI300X is designed for server installations performing heavy compute tasks with massive memory capacity and extreme FP16 throughput.

A user choosing between them would select based on the application environment. The 8065S supports display outputs, runs on 55 W, and fits as an IGP. The MI300X provides no display outputs, requires 750 W plus a 1150 W suggested PSU, and occupies an OAM module slot. The MI300X offers 192 GB of dedicated HBM3 memory versus system shared memory for the 8065S, a difference that matters for workloads exceeding available system RAM.

Benchmark results are absent, so no measured performance ranking exists. The specification comparison shows the MI300X exceeds the 8065S in FP32 throughput by a factor of 5.32, in FP16 throughput by a factor of 42.6, and in texture rate by a factor of 5.32. The 8065S exceeds the MI300X in pixel rate (192.0 GPixel/s versus 0 MPixel/s), boost clock (3000 MHz versus 2100 MHz), and API availability (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4 versus none).

Neither product has a launch MSRP recorded in the database. The 8065S holds an active production status, while the MI300X production status is not specified.

Q: What are the process nodes for each chip?

A: The 8065S uses a 4 nm process from TSMC, while the MI300X uses a 5 nm process from TSMC. The 8065S die measures 308 mm², and the MI300X die measures 1017 mm².

Architecture Differences

The AMD Radeon 8065S uses the Gorgon Halo chip based on RDNA 3.5 architecture, belonging to the Navi Mobile (RX 8000M) generation. The AMD Radeon Instinct MI300X uses the Aqua Vanjaram chip based on CDNA 3.0 architecture, belonging to the Radeon Instinct (MIx) generation. These are fundamentally different microarchitectures: RDNA 3.5 targets graphics rendering and consumer workloads, while CDNA 3.0 targets data center compute.

The 8065S integrates 2,560 shading units, 160 texture mapping units, 64 raster output units, and 40 ray tracing cores. The MI300X integrates 19,456 shading units and 1,216 texture mapping units but has zero raster output units and no ray tracing cores listed. The MI300X therefore allocates its silicon entirely to compute and memory throughput, while the 8065S maintains a full graphics pipeline including ray tracing hardware.

Neither product lists tensor cores in the database. The 8065S FP16 performance matches its FP32 at a 1:1 ratio, indicating no special half-precision acceleration. The MI300X FP16 performance reaches 653.7 TFLOPS at an 8:1 ratio, showing substantial specialized FP16 capability despite the absence of a tensor core field.

Transistor counts differ by orders of magnitude. The MI300X contains 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4 million per square millimeter. The 8065S transistor count is unknown, but its die area is 308 mm² on a 4 nm process, which suggests a higher density per area than the 5 nm MI300X given the smaller process node.

The MI300X memory clock is recorded as 2525 MHz with 10.1 Gbps effective speed, paired with HBM3 memory. The 8065S memory clock is system shared, meaning it depends on the host platform's memory configuration. The MI300X memory bus width of 8192 bit is the widest possible configuration for its HBM3 stack, while the 8065S depends entirely on system memory architecture.

The 8065S supports display outputs that are portable device dependent, meaning the specific connectors vary by laptop or handheld implementation. The MI300X has no display outputs at all, confirming its server-only orientation. The 8065S uses a PCIe 5.0 x16 bus interface, as does the MI300X, so both connect to their host systems through identical interface widths.
