AMD Instinct MI325X vs NVIDIA RTX 3500 Embedded Ada Generation Comparison

The Verdict

The database comparison between the AMD Instinct MI325X and the NVIDIA RTX 3500 Embedded Ada Generation reveals two devices built for entirely different segments of the computing market. The AMD Instinct MI325X is a massive accelerator oriented toward high-throughput compute workloads, while the NVIDIA RTX 3500 Embedded Ada Generation is a compact, power-efficient embedded solution. The recorded data shows no head-to-head benchmark wins for either side, and both devices occupy the 50th percentile among all GPUs in the database. This means the two products do not directly compete in the same performance class, and the choice between them depends strictly on the deployment environment and workload requirements.

For data center operators and researchers running large-scale AI or high-performance computing tasks, the AMD Instinct MI325X is the appropriate selection. Its enormous memory capacity, extremely wide memory bus, and high FP32 throughput place it in a category where the RTX 3500 Embedded Ada Generation cannot meaningfully participate. For system integrators and embedded developers needing a low-power, feature-complete GPU with modern API support and a small physical footprint, the NVIDIA RTX 3500 Embedded Ada Generation is the practical option. Its 100 W power envelope and IGP slot width make it suitable for compact systems where the 1000 W OAM module of the AMD part would be impossible to accommodate.

Where Each One Wins

The AMD Instinct MI325X wins decisively in raw compute throughput. Its FP32 performance of 81.72 TFLOPS is more than 3.5 times the 23.04 TFLOPS delivered by the NVIDIA RTX 3500 Embedded Ada Generation. The texture rate of 2,553.6 GTexel/s dwarfs the 360.0 GTexel/s of the NVIDIA part. Memory bandwidth is another dominant area: the AMD accelerator provides 6.14 TB/s, compared to 432.0 GB/s for the NVIDIA device. This represents a bandwidth advantage of more than an order of magnitude, which directly benefits memory-bound workloads such as large model inference, scientific simulations, and data-intensive processing.

The NVIDIA RTX 3500 Embedded Ada Generation wins in areas related to graphics capability, API compatibility, and power efficiency. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, whereas the AMD Instinct MI325X reports N/A for all three APIs. The NVIDIA part has 64 ROPs and a pixel rate of 144.0 GPixel/s, while the AMD accelerator reports 0 ROPs and 0 MPixel/s pixel rate, indicating the latter is not designed for rasterization workloads. The RTX 3500 also includes 40 RT cores and 160 tensor cores, features entirely absent from the AMD specification. Power consumption differs drastically: the NVIDIA device operates at 100 W with a suggested PSU of 300 W, while the AMD module draws 1000 W and requires a 1400 W suggested PSU.

Architecture Differences

The two devices come from different architectural lineages. The AMD Instinct MI325X uses the CDNA 3.0 architecture built on the Aqua Vanjaram chip, fabricated on a 5 nm process at TSMC. The NVIDIA RTX 3500 Embedded Ada Generation uses the Ada Lovelace architecture with the AD104 chip, also fabricated on a 5 nm process at TSMC. Both share the same process node and foundry, but their transistor counts and die sizes diverge substantially.

The AMD chip integrates 153,000 million transistors on a die size of 1017 mm², yielding a transistor density of 150.4M per mm². The NVIDIA chip contains 35,800 million transistors on a 294 mm² die, giving a density of 121.8M per mm². The AMD die is more than three times larger and holds more than four times the transistor count. The AMD accelerator features 19,456 shading units and 1,216 TMUs, while the NVIDIA part has 5,120 shading units and 160 TMUs. The AMD device reports no ROPs, RT cores, or tensor cores, whereas the NVIDIA part includes 64 ROPs, 40 RT cores, and 160 tensor cores.

Memory architecture differs fundamentally. The AMD Instinct MI325X uses 256 GB of HBM3e across an 8192 bit bus, while the NVIDIA RTX 3500 uses 12 GB of GDDR6 across a 192 bit bus. Clock behavior also differs: the AMD part has a base clock of 1000 MHz and boost clock of 2100 MHz, with memory running at 1500 MHz (6 Gbps effective). The NVIDIA part has a base clock of 1725 MHz and boost clock of 2250 MHz, with memory at 2250 MHz (18 Gbps effective). The NVIDIA device boosts higher, but the AMD device relies on its massive memory bus and shader count for throughput.

The AMD accelerator uses a PCIe 5.0 x16 bus interface and an OAM Module slot width with no power connectors. The NVIDIA device uses a PCIe 4.0 x16 bus interface and an IGP slot width, also with no power connectors. Neither device offers display outputs, reflecting their non-display compute or embedded orientations. The AMD part reports no production status, while the NVIDIA part is listed as Active. The AMD device has no launch MSRP, and neither product has a recorded launch price.

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparisons, and the win counts for both devices are zero. This absence of measured benchmarks means the comparison relies entirely on the specification data. The most significant performance indicators come from the compute and memory figures.

In FP32 throughput, the AMD Instinct MI325X reaches 81.72 TFLOPS, compared to the NVIDIA RTX 3500's 23.04 TFLOPS. The AMD part leads by a factor of roughly 3.5. FP16 performance follows the same pattern, with both devices reporting a 1:1 ratio, meaning the AMD part again delivers 81.72 TFLOPS versus 23.04 TFLOPS for the NVIDIA part. Texture rate shows a similar gap: the AMD device processes 2,553.6 GTexel/s, while the NVIDIA device processes 360.0 GTexel/s.

Memory bandwidth is the largest differentiator. The AMD Instinct MI325X provides 6.14 TB/s across an 8192 bit bus, while the NVIDIA RTX 3500 provides 432.0 GB/s across a 192 bit bus. This difference represents a bandwidth advantage of approximately 14.2 times for the AMD part. Memory capacity also favors the AMD device heavily: 256 GB versus 12 GB, a 21.3 times difference.

The NVIDIA RTX 3500 leads in pixel rate. It achieves 144.0 GPixel/s, while the AMD part reports 0 MPixel/s. This is consistent with the AMD device having zero ROPs, confirming it is not intended for rasterization. The NVIDIA part also has a higher boost clock at 2250 MHz versus 2100 MHz for the AMD part, and a higher base clock at 1725 MHz versus 1000 MHz.

The AMD Instinct MI325X uses the CDNA 3.0 architecture with the Aqua Vanjaram chip, while the NVIDIA RTX 3500 uses Ada Lovelace with the AD104 chip. Both use 5 nm TSMC fabrication, but the AMD die is 1017 mm² versus 294 mm² for the NVIDIA die. Transistor counts are 153,000 million versus 35,800 million, with transistor densities of 150.4M per mm² versus 121.8M per mm².

Shader resources differ: the AMD part has 19,456 shading units and 1,216 TMUs, while the NVIDIA part has 5,120 shading units and 160 TMUs. The AMD part has 0 ROPs, while the NVIDIA part has 64 ROPs. The NVIDIA part includes 40 RT cores and 160 tensor cores; the AMD part has none. Pixel rates are 0 MPixel/s for the AMD part versus 144.0 GPixel/s for the NVIDIA part. Texture rates are 2,553.6 GTexel/s versus 360.0 GTexel/s.

Memory configurations diverge completely: the AMD part uses 256 GB of HBM3e with an 8192 bit bus and 6.14 TB/s bandwidth, while the NVIDIA part uses 12 GB of GDDR6 with a 192 bit bus and 432.0 GB/s bandwidth. Clock speeds differ, with the AMD base at 1000 MHz and boost at 2100 MHz, and the NVIDIA base at 1725 MHz and boost at 2250 MHz. Memory clocks are 1500 MHz (6 Gbps effective) for the AMD part versus 2250 MHz (18 Gbps effective) for the NVIDIA part.

Power and physical specifications also diverge. The AMD TDP is 1000 W with a 1400 W suggested PSU and an OAM Module slot width. The NVIDIA TDP is 100 W with a 300 W suggested PSU and an IGP slot width. Neither device uses power connectors. The AMD part uses PCIe 5.0 x16, while the NVIDIA part uses PCIe 4.0 x16.
