AMD Instinct MI300X vs NVIDIA RTX 3500 Embedded Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data for these two accelerators is heavily one-sided in terms of benchmark availability. The AMD Instinct MI300X has a single recorded OpenCL benchmark score of 317,994 points in the Geekbench OpenCL test. The NVIDIA RTX 3500 Embedded Ada Generation has no benchmark entries in the database, resulting in an average benchmark score of zero and a percentile rank of 50 among all GPUs.

The MI300X sits at the 100th percentile of all GPUs in the database, meaning it outperforms every other recorded GPU in that specific OpenCL workload. Its nearest rivals provide useful context for interpreting this score. The NVIDIA H200 NVL posts an average score of 334,891, which is 5% higher than the MI300X. The NVIDIA B200 reaches 345,482, an 8% advantage over the MI300X. Conversely, the MI300X leads the NVIDIA L40S by 7.5% (295,763 versus 317,994) and the NVIDIA RTX 6000 Ada Generation by 10.7% (287,237 versus 317,994).

The RTX 3500 Embedded Ada Generation cannot be compared directly on any benchmark because it has no recorded scores. The database shows zero wins for either side in head-to-head comparisons, reflecting the absence of matched test data rather than any performance equivalence. The MI300X delivers a massive raw compute result, but the RTX 3500 Embedded presents no measured data for the database to analyze.

Architecture Differences

The AMD Instinct MI300X uses the Aqua Vanjaram chip built on CDNA 3.0 architecture, manufactured by TSMC on a 5 nm process. It integrates 153,000 million transistors across a die size of 1017 mm², yielding a transistor density of 150.4 million per square millimeter. The NVIDIA RTX 3500 Embedded Ada Generation uses the AD104 chip with Ada Lovelace architecture, also on TSMC 5 nm, but with 35,800 million transistors on a 294 mm² die, for a density of 121.8 million per square millimeter.

The MI300X carries 19,456 shading units, 1,216 texture mapping units, and no ROPs or ray tracing cores. Its pixel rate is recorded as 0 MPixel/s, and its texture rate reaches 2,553.6 GTexel/s. The RTX 3500 Embedded has 5,120 shading units, 160 TMUs, 64 ROPs, 40 ray tracing cores, and 160 tensor cores. Its pixel rate is 144.0 GPixel/s, and its texture rate is 360.0 GTexel/s.

Memory configurations diverge sharply. The MI300X uses 192 GB of HBM3 on an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The RTX 3500 Embedded uses 12 GB of GDDR6 on a 192-bit bus, with 432.0 GB/s of bandwidth. Clock behavior also differs: the MI300X runs at a base of 1000 MHz and a boost of 2100 MHz, with memory at 1300 MHz (5.2 Gbps effective). The RTX 3500 Embedded runs at a base of 1725 MHz and a boost of 2250 MHz, with memory at 2250 MHz (18 Gbps effective).

Compute throughput shows the MI300X at 81.72 TFLOPS for both FP32 and FP16 (1:1 ratio). The RTX 3500 Embedded delivers 23.04 TFLOPS for both FP32 and FP16 (1:1 ratio). The MI300X uses a PCIe 5.0 x16 interface, while the RTX 3500 Embedded uses PCIe 4.0 x16. The MI300X is an OAM module with no power connectors and no display outputs. The RTX 3500 Embedded is an IGP with no power connectors and no display outputs.

API support differs completely. The MI300X reports N/A for DirectX, OpenGL, and Vulkan. The RTX 3500 Embedded supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI300X draws a TDP of 750 W with a suggested PSU of 1150 W. The RTX 3500 Embedded draws 100 W with a suggested PSU of 300 W.

Where Each One Wins

The AMD Instinct MI300X wins in raw compute performance based on the only benchmark score available. Its 317,994 OpenCL result places it at the top of the database, ahead of the L40S by 7.5% and the RTX 6000 Ada Generation by 10.7%. The MI300X also wins on memory capacity, bandwidth, shading units, texture rate, FP32 and FP16 throughput, and transistor count. It uses a larger die, higher transistor density, and newer PCIe generation. Its architecture targets high-throughput compute workloads without any graphics API support, which matches its OAM form factor and lack of display outputs.

The NVIDIA RTX 3500 Embedded Ada Generation wins on power efficiency metrics within the recorded data. It operates at 100 W TDP compared to the MI300X's 750 W, and its suggested PSU is 300 W versus 1150 W. It has a higher base clock (1725 MHz versus 1000 MHz) and a higher boost clock (2250 MHz versus 2100 MHz). It includes ROPs, ray tracing cores, tensor cores, and full graphics API support. It also has a higher memory clock at 18 Gbps effective versus 5.2 Gbps effective, although with a much narrower bus and less total memory.

The RTX 3500 Embedded wins on feature completeness for graphics-oriented tasks. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the MI300X has no graphics API support. The RTX 3500 Embedded has a pixel rate of 144.0 GPixel/s, whereas the MI300X records 0 MPixel/s. The RTX 3500 Embedded has 40 ray tracing cores and 160 tensor cores, features entirely absent from the MI300X's specifications.

The MI300X wins on memory scalability. Its 192 GB HBM3 pool dwarfs the 12 GB GDDR6 on the RTX 3500 Embedded. The bandwidth difference is similarly lopsided: 5.32 TB/s versus 432.0 GB/s. The 8192-bit bus on the MI300X provides 42.7 times the bus width of the RTX 3500 Embedded's 192-bit bus, based on the recorded figures.
