AMD Instinct MI308X vs NVIDIA RTX 1000 Mobile Ada Generation Comparison

Where Each One Wins

The AMD Instinct MI308X and NVIDIA RTX 1000 Mobile Ada Generation occupy entirely different segments of the GPU market, and the recorded data reflects that split clearly. The MI308X is a datacenter accelerator with no display outputs, designed for compute workloads in server environments. The RTX 1000 Mobile Ada Generation is a mobile integrated graphics processor for laptops, with its display output described as portable device dependent.

The MI308X wins in raw compute throughput, memory capacity, and memory bandwidth. Its FP32 throughput of 81.72 TFLOPS is roughly 7.9 times the RTX 1000 Mobile's 10.37 TFLOPS. The texture rate of 2,553.6 GTexel/s compared to 162.0 GTexel/s shows a similar ratio of advantage. The memory subsystem is where the gap becomes extreme: 192 GB of HBM3 versus 6 GB of GDDR6, with bandwidth of 5.32 TB/s versus 192.0 GB/s.

The RTX 1000 Mobile Ada Generation wins in power efficiency and feature completeness for graphics workloads. Its TDP of 35 W is drastically lower than the MI308X's 750 W, making it suitable for battery-powered devices. It also carries dedicated RT cores (20) and tensor cores (80), which the MI308X does not list. The RTX 1000 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI308X lists N/A for all three APIs. Pixel rate of 97.20 GPixel/s versus 0 MPixel/s further confirms the RTX 1000 is the only one of the two capable of rasterization output.

Neither part has recorded benchmark scores in the database, so both sit at the 50th percentile among all GPUs with an average benchmark score of 0. The head-to-head benchmark array is empty, and neither item has any nearest rivals listed. The analysis below therefore relies on the specification data as recorded.

Architecture Differences

The two chips come from different architectural lineages. The MI308X uses CDNA 3.0 architecture on the Aqua Vanjaram chip, fabricated by TSMC on a 5 nm process. It packs 153,000 million transistors onto a 1017 mm² die, yielding a transistor density of 150.4M per mm². The RTX 1000 Mobile uses Ada Lovelace architecture on the AD107 chip, also fabricated by TSMC on 5 nm, but with 18,900 million transistors on a 159 mm² die for a density of 118.9M per mm².

The transistor count difference is enormous. The MI308X has about 8.1 times as many transistors as the RTX 1000 Mobile. The die area difference is even larger, with the MI308X at roughly 6.4 times the physical size. The MI308X belongs to the Instinct (MIx) generation and succeeds the Radeon Instinct line. The RTX 1000 Mobile is part of the GeForce 10-series, in the Ada-MW (x000A) generation, succeeding Ampere-MW and succeeded by Blackwell-MW.

Memory architecture differs fundamentally. The MI308X uses HBM3 with an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The RTX 1000 Mobile uses GDDR6 with a 96-bit bus, delivering 192.0 GB/s. The memory clock also differs: 1300 MHz (5.2 Gbps effective) on the MI308X versus 2000 MHz (16 Gbps effective) on the RTX 1000 Mobile. The RTX 1000's higher memory clock does not compensate for its much narrower bus.

Shader resources are heavily skewed. The MI308X has 19,456 shading units, 1,216 TMUs, and 0 ROPs. The RTX 1000 Mobile has 2,560 shading units, 80 TMUs, and 48 ROPs. The MI308X has no listed RT cores or tensor cores, while the RTX 1000 Mobile lists 20 RT cores and 80 tensor cores. Clock speeds are comparable in boost: the MI308X boosts to 2100 MHz, the RTX 1000 Mobile to 2025 MHz. Base clocks differ more, with the MI308X at 1000 MHz and the RTX 1000 at 1485 MHz.

Power delivery differs by design. The MI308X is an OAM module with no power connectors, requiring a suggested PSU of 1150 W. The RTX 1000 Mobile is an IGP with no power connectors and no suggested PSU listed. Bus interfaces also differ: PCIe 5.0 x16 for the MI308X versus PCIe 4.0 x8 for the RTX 1000 Mobile.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for these two parts. The headToHeadBenchmarks array is empty, and the wins counters show 0 for both items. Without measured performance data, the comparison must rest entirely on the specification sheet.

The largest documented advantage for the MI308X is in memory bandwidth. At 5.32 TB/s, it delivers roughly 27.7 times the bandwidth of the RTX 1000 Mobile's 192.0 GB/s. Memory capacity follows a similar pattern: 192 GB versus 6 GB, a 32-fold difference. FP32 compute shows the MI308X at 81.72 TFLOPS, which is approximately 7.9 times the RTX 1000's 10.37 TFLOPS. FP16 throughput matches FP32 on both parts at a 1:1 ratio, so the same multiplier applies: 81.72 TFLOPS versus 10.37 TFLOPS.

Texture rate favors the MI308X at 2,553.6 GTexel/s, about 15.8 times the RTX 1000 Mobile's 162.0 GTexel/s. The RTX 1000 Mobile counters in pixel rate, where it records 97.20 GPixel/s while the MI308X records 0 MPixel/s. The MI308X has no ROPs, so it cannot perform pixel output at all.

Clock behavior shows the RTX 1000 Mobile with a higher base clock of 1485 MHz versus 1000 MHz on the MI308X. Boost clocks are closer: 2025 MHz versus 2100 MHz, a 3.7% advantage for the MI308X. The RTX 1000 Mobile's memory clock of 2000 MHz exceeds the MI308X's 1300 MHz, but the effective data rate of 16 Gbps versus 5.2 Gbps reflects the different memory technologies.

Power consumption is a decisive differentiator. The MI308X has a TDP of 750 W, while the RTX 1000 Mobile has a TDP of 35 W. The ratio is about 21.4 to 1. The suggested PSU for the MI308X is 1150 W, which further indicates the scale of its power requirements.

The specification comparison shows two products with no overlap in intended use. The MI308X is a 750 W OAM accelerator with no display output and no graphics API support, built for memory-bound compute workloads. The RTX 1000 Mobile Ada Generation is a 35 W integrated mobile GPU with full graphics API support, RT cores, tensor cores, and a display output path. The 5 nm process node is shared, but everything else diverges.
