AMD Instinct MI308X vs NVIDIA RTX 4000 Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data does not contain direct head-to-head benchmark comparisons between the AMD Instinct MI308X and the NVIDIA RTX 4000 Ada Generation. The head-to-head benchmark array is empty, and the win counts for both products are zero. However, the database provides benchmark results for the RTX 4000 Ada Generation, along with its percentile ranking and nearest rival comparisons, which allows for a meaningful analysis of its measured performance.

The RTX 4000 Ada Generation delivers a Geekbench OpenCL score of 146,593 and a Geekbench Vulkan score of 123,842. Its average benchmark score across recorded tests is 135,218. This places the card in the 95th percentile among all GPUs tracked in the database, indicating that it outperforms the vast majority of recorded graphics hardware in the synthetic workloads used.

The nearest rivals for the RTX 4000 Ada Generation, based on average benchmark scores, are all AMD professional cards. The NVIDIA A10M posts an average score of 135,230, which is effectively identical to the RTX 4000 Ada Generation with a delta percentage of 0. The AMD Radeon PRO W6800 scores 135,396, a delta of -0.1 percent relative to the RTX 4000 Ada Generation. The AMD Radeon Pro W6800X Duo achieves 135,774, a delta of -0.4 percent. The AMD Radeon PRO V620 records 136,472, a delta of -0.9 percent. These deltas are all within one percentage point, indicating that the RTX 4000 Ada Generation trades blows with its closest competitors within a narrow performance band in the aggregate benchmark score.

Because the MI308X has no recorded benchmarks, no percentile ranking, and no average score in the database, there is no measured performance data to compare against the RTX 4000 Ada Generation. The MI308X sits at the 50th percentile among all GPUs, but this value is not tied to any benchmark results, making it a placeholder rather than a reflection of tested performance. The database records zero benchmark entries for the MI308X, so any direct performance comparison between the two accelerators cannot be substantiated with measured numbers.

The RTX 4000 Ada Generation's OpenCL score of 146,593 is notably higher than its Vulkan score of 123,842, a gap of roughly 18 percent in favor of OpenCL. This suggests the card's compute-oriented workloads through OpenCL scale better than its graphics-oriented Vulkan path, at least in the specific tests recorded. The average score of 135,218 sits between these two values, which is consistent with an average of the two recorded submissions.

Where Each One Wins

Based strictly on recorded data, the NVIDIA RTX 4000 Ada Generation wins in every measurable category because it is the only product with benchmark results. Its OpenCL score of 146,593 and Vulkan score of 123,842 establish a clear performance baseline. The card's 95th percentile ranking confirms that its measured performance is well above the median GPU in the database.

The AMD Instinct MI308X has no recorded wins, no benchmarks, and no average score. Its 50th percentile ranking, without supporting measurements, does not constitute a performance outcome. In the absence of tested data, the MI308X cannot be assigned wins in any workload category.

For users seeking a workstation accelerator with verified compute and graphics performance, the RTX 4000 Ada Generation demonstrates strong results in the recorded OpenCL and Vulkan tests. Its nearest rivals, all within one percentage point of its average score, indicate that the card sits at the top of a tightly clustered group of professional GPUs. The MI308X, by contrast, offers no measured evidence of performance in the database, leaving its standing undefined.

Specification Differences

The two accelerators differ substantially across nearly every hardware specification. The AMD Instinct MI308X uses an AMD Aqua Vanjaram chip built on CDNA 3.0 architecture, while the NVIDIA RTX 4000 Ada Generation uses an AD104 chip built on Ada Lovelace architecture. Both are fabricated on a 5 nm process at TSMC, but the transistor counts diverge sharply: the MI308X contains 153,000 million transistors on a 1017 mm² die, while the RTX 4000 Ada Generation contains 35,800 million transistors on a 294 mm² die. Transistor density also differs, with the MI308X at 150.4M / mm² and the RTX 4000 Ada Generation at 121.8M / mm².

Memory configurations are entirely different. The MI308X carries 192 GB of HBM3 on an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The RTX 4000 Ada Generation carries 20 GB of GDDR6 on a 160-bit bus, delivering 360.0 GB/s. Clock speeds also differ: the MI308X has a base clock of 1000 MHz and a boost clock of 2100 MHz, while the RTX 4000 Ada Generation has a base clock of 1500 MHz and a boost clock of 2175 MHz. Memory clocks are listed as 1300 MHz (5.2 Gbps effective) for the MI308X and 2250 MHz (18 Gbps effective) for the RTX 4000 Ada Generation.

Compute resources differ by an order of magnitude in some cases. The MI308X has 19,456 shading units and 1,216 texture mapping units, while the RTX 4000 Ada Generation has 6,144 shading units and 192 texture mapping units. The MI308X has 0 ROPs and a pixel rate of 0 MPixel/s, whereas the RTX 4000 Ada Generation has 64 ROPs and a pixel rate of 139.2 GPixel/s. Texture rates are 2,553.6 GTexel/s for the MI308X and 417.6 GTexel/s for the RTX 4000 Ada Generation. FP32 and FP16 compute are both 81.72 TFLOPS for the MI308X, while the RTX 4000 Ada Generation delivers 26.73 TFLOPS in both formats.

Power and physical specifications also diverge. The MI308X has a TDP of 750 W and uses an OAM Module slot width with no power connectors; it suggests a 1150 W power supply. The RTX 4000 Ada Generation has a TDP of 130 W, a single-slot form factor, one 16-pin power connector, and a suggested 300 W power supply. The MI308X uses PCIe 5.0 x16, while the RTX 4000 Ada Generation uses PCIe 4.0 x16. Display outputs are absent on the MI308X, while the RTX 4000 Ada Generation provides 4x DisplayPort 1.4a.

Architecture Differences

The architectural divide between the two products is fundamental. The AMD Instinct MI308X is built on CDNA 3.0, AMD's compute-focused architecture designed for data center acceleration. It has no display outputs, no ROPs, and no API support for DirectX, OpenGL, or Vulkan, all of which are recorded as N/A. This indicates a pure compute accelerator with no graphics pipeline. The chip, named Aqua Vanjaram, is a massive 1017 mm² design with 153,000 million transistors, reflecting a density of 150.4M / mm². Its memory subsystem uses HBM3 across an 8192-bit bus, yielding 5.32 TB/s of bandwidth, which is suited for large-scale data movement.

The NVIDIA RTX 4000 Ada Generation is built on Ada Lovelace, an architecture that supports full graphics and compute workloads. It includes 48 ray tracing cores and 192 tensor cores, features entirely absent from the MI308X's specification sheet. The RTX 4000 Ada Generation supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it a complete workstation GPU. Its memory is GDDR6 on a 160-bit bus, which is narrower and slower than the MI308X's HBM3 implementation, but it also carries display outputs, enabling direct visual output.

The MI308X has no ray tracing cores, no tensor cores, and no ROPs, reinforcing its role as a specialized accelerator rather than a general-purpose graphics card. The RTX 4000 Ada Generation, with its 64 ROPs and 139.2 GPixel/s pixel rate, is capable of rasterization and display output. The MI308X's 2,553.6 GTexel/s texture rate is over six times higher than the RTX 4000 Ada Generation's 417.6 GTexel/s, reflecting its massive shading unit count.

Release dates differ by several months. The MI308X was released on December 5, 2023, while the RTX 4000 Ada Generation was released on August 8, 2023. The RTX 4000 Ada Generation is listed as Active in production status, with a predecessor of Workstation Ampere and a successor of Blackwell PRO W. The MI308X has no production status listed, a predecessor of Radeon Instinct, and no successor. The RTX 4000 Ada Generation has physical dimensions of 245 mm in length and 112 mm in height; the MI308X has no recorded dimensions.

The architectural choices reflect different design goals. The MI308X prioritizes raw compute throughput, memory bandwidth, and capacity at the cost of power and physical size. The RTX 4000 Ada Generation balances compute, graphics, and efficiency, fitting into a single-slot 130 W envelope with full display and API support. The data shows two products optimized for divergent use cases, with no overlap in measured performance metrics.
