AMD Instinct MI300 vs NVIDIA RTX 3500 Embedded Ada Generation Comparison

Head-to-Head Benchmarks

The database holds no recorded benchmark scores for either the AMD Instinct MI300 or the NVIDIA RTX 3500 Embedded Ada Generation. Both entries report an avgBenchmarkScore of 0 and a percentileVsAllGpus of 50, with no head-to-head benchmark entries and zero wins attributed to either side. This means there is no direct performance comparison data available in the database, and any inference about relative speed must come from raw specification analysis rather than measured results.

The MI300 delivers an FP32 compute rating of 47.87 TFLOPS, while the RTX 3500 Embedded Ada Generation provides 23.04 TFLOPS. That places the AMD part at roughly double the raw single-precision throughput on paper. Similarly, FP16 performance follows the same 1:1 ratio pattern, with the MI300 at 47.87 TFLOPS and the RTX 3500 at 23.04 TFLOPS. Texture rate also favors the MI300, which records 1,496.0 GTexel/s against 360.0 GTexel/s for the NVIDIA part, a margin of more than four times. The MI300 lists a pixel rate of 0 MPixel/s, while the RTX 3500 manages 144.0 GPixel/s, so the NVIDIA chip holds a clear advantage in rasterization throughput where pixel output matters.

Memory bandwidth is another area of large divergence. The MI300 carries 128 GB of HBM3 across an 8192-bit bus, yielding 5.32 TB/s. The RTX 3500 uses 12 GB of GDDR6 on a 192-bit interface, producing 432.0 GB/s. That means the AMD accelerator provides over twelve times the memory bandwidth of the NVIDIA embedded part. Clock speeds also differ substantially: the MI300 runs a base of 1000 MHz and boosts to 1700 MHz, while the RTX 3500 starts at 1725 MHz and boosts to 2250 MHz. The NVIDIA chip operates at higher frequencies, but its much smaller memory bus and lower core counts limit its aggregate throughput.

Architecture Differences

The AMD Instinct MI300 uses the CDNA 3.0 architecture on a 5 nm TSMC process, with the chip codenamed Aqua Vanjaram. The NVIDIA RTX 3500 Embedded Ada Generation also uses a 5 nm TSMC process but adopts the Ada Lovelace architecture, built around the AD104 chip. Both parts come from TSMC, and both are on the same process node, but the transistor counts differ enormously. The MI300 integrates 153,000 million transistors across a die size of 1017 mm², while the RTX 3500 packs 35,800 million transistors onto a 294 mm² die. The resulting transistor density is 150.4M per mm² for the AMD part and 121.8M per mm² for the NVIDIA part, meaning the MI300 uses its silicon area more densely.

Core configuration separates the two further. The MI300 has 14,080 shading units, 880 texture mapping units, and no ROPs listed. The RTX 3500 contains 5,120 shading units, 160 TMUs, and 64 ROPs. The NVIDIA chip also includes 40 RT cores and 160 tensor cores, while the MI300 entry shows no RT core or tensor core counts, consistent with its compute-focused CDNA design that omits dedicated ray tracing hardware. The MI300 lists no API support for DirectX, OpenGL, or Vulkan, while the RTX 3500 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. That difference reflects the MI300's role as a datacenter accelerator without display or graphics APIs, versus the RTX 3500's embedded graphics capability, even though both parts report no display outputs.

Memory architecture also diverges completely. The MI300 uses HBM3 with a bus width of 8192 bits and a memory clock of 1300 MHz, delivering 5.32 TB/s. The RTX 3500 uses GDDR6 with a 192-bit bus and a memory clock of 2250 MHz, achieving 432.0 GB/s. The MI300's power envelope is 600 W with a suggested PSU of 1000 W and two 8-pin power connectors. The RTX 3500 consumes only 100 W, requires no external power connectors, and suggests a 300 W PSU. The MI300's physical dimensions are 267 mm in length and 111 mm in height, while the RTX 3500 is an IGP form factor with no listed dimensions.

Where Each One Wins

The AMD Instinct MI300 wins decisively in raw compute throughput. Its 47.87 TFLOPS FP32 rating doubles the RTX 3500's 23.04 TFLOPS, and its texture rate of 1,496.0 GTexel/s exceeds the NVIDIA part by a factor of roughly four. The MI300 also dominates in memory capacity and bandwidth: 128 GB versus 12 GB, and 5.32 TB/s versus 432.0 GB/s. This configuration suits workloads that demand large datasets resident in memory and sustained high-bandwidth access, such as training large models or processing massive matrices. The MI300's 8192-bit bus and HBM3 memory deliver bandwidth that the GDDR6-based RTX 3500 cannot approach.

The NVIDIA RTX 3500 Embedded Ada Generation wins on power efficiency and compactness. It draws only 100 W against the MI300's 600 W, requires no external power connectors, and suggests a 300 W PSU instead of 1000 W. The RTX 3500 also runs at higher clock speeds, 1725 MHz base and 2250 MHz boost, and includes 40 RT cores and 160 tensor cores, features absent from the MI300's specification list. Its 144.0 GPixel/s pixel rate indicates strong rasterization capability, and its support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 makes it usable in graphics contexts where the MI300 offers no API compatibility. The IGP form factor and PCIe 4.0 x16 interface suit embedded deployments where space and power are constrained.

The MI300's PCIe 5.0 x16 interface provides twice the generation bandwidth of the RTX 3500's PCIe 4.0 x16, but that advantage matters only in systems with compatible host controllers. The MI300's 267 mm length and 111 mm height indicate a full-sized accelerator, while the RTX 3500's IGP design suggests a much smaller footprint, though the database records no exact dimensions for the NVIDIA part. The MI300 also lacks display outputs, as does the RTX 3500, so neither card targets direct video output.

For compute-centric datacenter tasks, the MI300 shows clear specification superiority in every throughput metric recorded. For embedded graphics, ray tracing, or power-limited environments, the RTX 3500 provides the only viable path given its RT cores, graphics API support, and much lower power draw. The RTX 3500 also holds an edge in production status, listed as Active, while the MI300's production status remains unrecorded. The RTX 3500 has a defined successor in Blackwell-MW, while the MI300 lists no successor. Release dates sit close together, with the MI300 arriving on 2023-01-03 and the RTX 3500 on 2023-03-20, but their intended markets diverge sharply based on the recorded specifications.
