AMD Instinct MI300 vs NVIDIA RTX 3000 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The database does not contain any recorded benchmark scores for either the AMD Instinct MI300 or the NVIDIA RTX 3000 Mobile Ada Generation. Both entries show an average benchmark score of zero, and the head-to-head benchmark array is empty. Consequently, there are no wins recorded for either product, with both the MI300 and the RTX 3000 Mobile Ada holding zero wins in direct comparisons.

This absence of measured performance data means that any quantitative comparison between the two accelerators must rely entirely on their recorded specifications rather than on empirical test results. The percentile ranking for both products against all GPUs in the database is identical at the 50th percentile, which reflects the lack of benchmark scores rather than any equivalence in real-world capability.

The raw compute figures show a substantial gap. The AMD Instinct MI300 delivers 47.87 TFLOPS for both FP32 and FP16 operations, with a 1:1 ratio between the two precision formats. The NVIDIA RTX 3000 Mobile Ada Generation delivers 15.62 TFLOPS for FP32 and the same 15.62 TFLOPS for FP16, also at a 1:1 ratio. In pure floating-point throughput, the MI300 is roughly three times faster than the RTX 3000 Mobile Ada, though the absence of measured benchmarks means this specification-level advantage has not been validated through the database's testing methodology.

Texture processing shows a similar disparity. The MI300 achieves a texture rate of 1,496.0 GTexel/s, while the RTX 3000 Mobile Ada reaches 244.1 GTexel/s. The MI300's advantage here is approximately sixfold. Pixel rate, however, tells a different story: the MI300 records 0 MPixel/s, while the RTX 3000 Mobile Ada achieves 81.36 GPixel/s. This reflects the fundamentally different design goals of the two products, as the MI300 has no display outputs and is not intended for rasterized graphics rendering.

FAQ

Architecture Differences

The two products represent fundamentally different architectural philosophies from their respective manufacturers. The AMD Instinct MI300 uses the CDNA 3.0 architecture, built on the Aqua Vanjaram chip, and belongs to the Instinct (MIx) generation. It is a dedicated compute accelerator designed for data center workloads, as evidenced by the absence of display outputs and the lack of any graphics API support. The NVIDIA RTX 3000 Mobile Ada Generation uses the Ada Lovelace architecture, built on the AD106 chip, and belongs to the GeForce 30-series line within the Ada-MW generation. It is a mobile workstation GPU with full graphics API support, including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The silicon differences are dramatic. The MI300 uses a 1017 mm² die with 153,000 million transistors, resulting in a transistor density of 150.4 million transistors per square millimeter. The RTX 3000 Mobile Ada uses a 188 mm² die with 22,900 million transistors, giving a density of 121.8 million transistors per square millimeter. Both are fabricated on TSMC's 5 nm process, but the MI300's die is more than five times larger and packs nearly seven times the transistor count.

Compute resource allocation diverges sharply. The MI300 has 14,080 shading units, 880 texture mapping units, and 0 raster operation units. The RTX 3000 Mobile Ada has 4,608 shading units, 144 texture mapping units, and 48 raster operation units. The MI300 also has no ray tracing cores and no tensor cores, while the RTX 3000 Mobile Ada includes 36 ray tracing cores and 144 tensor cores. This reflects the MI300's focus on raw compute throughput for AI and scientific workloads, while the RTX 3000 Mobile Ada is built for graphics rendering, ray tracing, and AI-accelerated features in a mobile form factor.

Memory architecture is equally divergent. The MI300 uses 128 GB of HBM3 memory across an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The RTX 3000 Mobile Ada uses 8 GB of GDDR6 memory across a 128-bit bus, delivering 256.0 GB/s. The MI300's memory bandwidth is over twenty times higher, a necessity for feeding its large compute array, while the RTX 3000 Mobile Ada's smaller memory pool is sufficient for mobile rendering workloads.

Clock speeds and power envelopes reflect their different deployment scenarios. The MI300 runs at a base clock of 1000 MHz and a boost clock of 1700 MHz, with a TDP of 600 W. The RTX 3000 Mobile Ada runs at a base clock of 1395 MHz and a boost clock of 1695 MHz, with a TDP of 115 W. The MI300's higher power draw enables its larger compute array, while the RTX 3000 Mobile Ada's lower power envelope suits battery-powered mobile systems.

Bus interfaces also differ. The MI300 uses PCIe 5.0 x16, while the RTX 3000 Mobile Ada uses PCIe 4.0 x16. The MI300's interface provides double the bandwidth of the older PCIe 4.0 standard. The RTX 3000 Mobile Ada is classified as an IGP (integrated graphics processor) in terms of slot width, while the MI300 has no slot width listed.

The Verdict

The recorded data indicates that the AMD Instinct MI300 is a server-grade compute accelerator with massive memory capacity, extremely high bandwidth, and dominant raw compute throughput. The NVIDIA RTX 3000 Mobile Ada Generation is a mobile workstation graphics processor with ray tracing support, tensor cores, display outputs, and full graphics API compatibility. These are not competing products in the same market segment; they serve entirely different purposes.

For workloads that demand maximum FP32 or FP16 compute throughput, the MI300's 47.87 TFLOPS in both precisions is three times the RTX 3000 Mobile Ada's 15.62 TFLOPS. For memory-intensive applications, the MI300's 128 GB HBM3 pool with 5.32 TB/s bandwidth is in a different class from the RTX 3000 Mobile Ada's 8 GB GDDR6 with 256.0 GB/s. The MI300 also has a nearly sixfold advantage in texture rate at 1,496.0 GTexel/s versus 244.1 GTexel/s.

However, the RTX 3000 Mobile Ada offers capabilities the MI300 lacks entirely. It supports ray tracing with 36 dedicated cores, includes 144 tensor cores for AI acceleration, and provides full graphics API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. It also has display outputs, albeit dependent on the portable device, and can render pixels at 81.36 GPixel/s. The MI300 has no display outputs, no graphics API support, and a pixel rate of 0 MPixel/s.

The power requirements make the deployment contexts clear. The MI300 requires 600 W and a 1000 W power supply, with two 8-pin connectors. The RTX 3000 Mobile Ada requires 115 W and no external power connectors, fitting into a mobile form factor. The MI300's physical dimensions are listed as 267 mm in length and 111 mm in height, while the RTX 3000 Mobile Ada has no listed dimensions, consistent with its IGP classification.

The MI300 was released on January 3, 2023, while the RTX 3000 Mobile Ada was released on March 20, 2023. The MI300's predecessor is the Radeon Instinct series, while the RTX 3000 Mobile Ada's predecessor is the Ampere-MW series and its successor is the Blackwell-MW series.
