AMD Instinct MI308X vs NVIDIA RTX 2000 Embedded Ada Generation Comparison

The Verdict

The AMD Instinct MI308X and NVIDIA RTX 2000 Embedded Ada Generation occupy entirely different segments of the hardware spectrum, and the recorded data shows no benchmark overlap between them. The MI308X is a data-center compute accelerator built around the CDNA 3.0 architecture, delivering 81.72 TFLOPS of FP32 performance with 192 GB of HBM3 memory. The RTX 2000 Embedded Ada Generation is a low-power embedded GPU from the Ada Lovelace architecture, producing 12.35 TFLOPS FP32 with 8 GB of GDDR6 memory.

The MI308X targets high-throughput compute workloads where massive memory capacity and bandwidth are critical. Its 192 GB memory capacity and 5.32 TB/s bandwidth dwarf the RTX 2000's 8 GB and 256.0 GB/s. The RTX 2000 Embedded Ada Generation, by contrast, is designed for portable or embedded systems where power draw is constrained, operating at 50 W versus the MI308X's 750 W. The RTX 2000 includes graphics output support (Portable Device Dependent), while the MI308X has no display outputs. Users requiring dense compute acceleration with HBM3 memory should select the AMD part; those needing embedded graphics with ray tracing and AI tensor cores at low power should choose the NVIDIA part.

Architecture Differences

The AMD Instinct MI308X uses the Aqua Vanjaram chip built on TSMC's 5 nm process, containing 153,000 million transistors across a 1017 mm² die. The transistor density measures 150.4 million transistors per mm². The architecture is CDNA 3.0, a compute-focused design with no graphics pipeline, as evidenced by 0 ROPs, 0 MPixel/s pixel rate, and no support for DirectX, OpenGL, or Vulkan. The chip integrates 19,456 shading units and 1,216 texture mapping units, with a texture rate of 2,553.6 GTexel/s.

The NVIDIA RTX 2000 Embedded Ada Generation uses the AD107 chip, also fabricated on TSMC's 5 nm process, but with 18,900 million transistors on a 159 mm² die, yielding a transistor density of 118.9 million per mm². The Ada Lovelace architecture includes a full graphics pipeline: 3,072 shading units, 96 TMUs, 48 ROPs, 24 ray tracing cores, and 96 tensor cores. The pixel rate is 96.48 GPixel/s, and the texture rate is 193.0 GTexel/s. The RTX 2000 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, indicating complete graphics and compute capability.

The memory subsystems differ fundamentally. The MI308X uses HBM3 with a 8192-bit bus width, while the RTX 2000 uses GDDR6 with a 128-bit bus. The MI308X memory clock runs at 1300 MHz (5.2 Gbps effective), whereas the RTX 2000 memory clock is 2000 MHz (16 Gbps effective). The MI308X has no power connectors and is an OAM Module, while the RTX 2000 is an IGP with no power connectors and a PCIe 4.0 x16 interface. The MI308X uses PCIe 5.0 x16. The MI308X's release date was December 2023, while the RTX 2000 launched in March 2023. The MI308X's predecessor is Radeon Instinct, while the RTX 2000's predecessor is Ampere-MW and its successor is Blackwell-MW.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between these two accelerators, and neither has an average benchmark score above zero. Both sit at the 50th percentile among all GPUs in the database, which reflects the absence of measured performance data rather than equivalence in capability. The wins tally shows zero for each part, so a direct numerical comparison from benchmark runs is not available.

Instead, the specification data provides the basis for comparison. The MI308X delivers 81.72 TFLOPS FP32, which is 6.6 times the RTX 2000's 12.35 TFLOPS. The FP16 figure follows the same 1:1 ratio for both: 81.72 TFLOPS for the AMD part and 12.35 TFLOPS for the NVIDIA part. The texture rate favors the MI308X at 2,553.6 GTexel/s versus 193.0 GTexel/s, a 13.2-fold advantage. The pixel rate is inverted: the RTX 2000 outputs 96.48 GPixel/s, while the MI308X outputs 0 MPixel/s because it lacks ROPs.

Memory bandwidth shows the largest relative gap. The MI308X's 5.32 TB/s exceeds the RTX 2000's 256.0 GB/s by a factor of 20.8. Memory capacity differs by 24 times: 192 GB versus 8 GB. The bus width difference is 64 times: 8192 bit versus 128 bit. Clock speeds are closer: the MI308X boosts to 2100 MHz, while the RTX 2000 boosts to 2010 MHz. The base clocks differ more, with the MI308X at 1000 MHz and the RTX 2000 at 1530 MHz.

Power consumption is where the RTX 2000 dominates. Its 50 W TDP is 15 times lower than the MI308X's 750 W. The MI308X requires a suggested power supply of 1150 W, whereas the RTX 2000 has no suggested PSU listed. The transistor count favors the MI308X by 8.1 times, but the die size difference is 6.4 times, which explains the higher transistor density of the AMD chip.
