AMD Instinct MI350X vs NVIDIA GeForce RTX 4070 AD103 Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark entries for the AMD Instinct MI350X against the NVIDIA GeForce RTX 4070 AD103. Both parts hold a percentile rank of 50 against all GPUs, with an average benchmark score of zero for each. This absence of direct measurements means the comparison must rely entirely on architectural and specification data.

The MI350X delivers 72.09 TFLOPS of FP32 compute, which is 2.47 times the 29.15 TFLOPS of the RTX 4070 AD103. In FP16, the ratio is identical: 72.09 TFLOPS versus 29.15 TFLOPS, with both parts running at a 1:1 ratio relative to their FP32 rates. Texture throughput shows a similar gap: 2,252.8 GTexel/s for the MI350X versus 455.4 GTexel/s for the RTX 4070 AD103, a factor of roughly 4.95.

The RTX 4070 AD103 counters in pixel processing. The NVIDIA part achieves 158.4 GPixel/s, while the MI350X is listed at 0 MPixel/s. The AMD accelerator has no ROPs, whereas the RTX 4070 AD103 has 64 ROPs. This makes the pixel-rate comparison one-sided in favor of the GeForce card.

Memory bandwidth is another decisive split. The MI350X shows 8.19 TB/s, while the RTX 4070 AD103 shows 504.2 GB/s. That is a 16.24 times difference in raw bandwidth. Memory capacity differs even more dramatically: 288 GB of HBM3e on the AMD side versus 12 GB of GDDR6X on the NVIDIA side, a 24 times capacity advantage.

Clock behavior also diverges. The RTX 4070 AD103 runs a base clock of 1920 MHz and boosts to 2475 MHz. The MI350X starts lower at 1000 MHz and boosts to 2200 MHz. Despite the lower clocks, the MI350X produces higher throughput because of its massive execution resource count: 16,384 shading units versus 5,888, and 1,024 TMUs versus 184.

Architecture Differences

The MI350X is built on CDNA 4.0 architecture, fabricated on a 3 nm process at TSMC. The RTX 4070 AD103 uses Ada Lovelace architecture on a 5 nm process, also from TSMC. The AMD chip integrates 185,000 million transistors across a die size of 2380 mm², yielding a transistor density of 77.7 million per mm². The NVIDIA chip packs 45,900 million transistors into 379 mm², achieving a higher density of 121.1 million per mm².

The MI350X is designated as an Instinct (MIx) generation part, with the chip identified as MI350 256CU. Its predecessor is listed as Radeon Instinct. The RTX 4070 AD103 belongs to the GeForce 40-series, uses the AD103 chip, and follows the GeForce 30 line as its predecessor. Production status for the MI350X is not recorded, while the RTX 4070 AD103 is marked as end-of-life.

Memory architecture highlights the fundamental divergence. The MI350X uses HBM3e with a 8192-bit bus and 288 GB capacity. The RTX 4070 AD103 uses GDDR6X with a 192-bit bus and 12 GB capacity. The memory clock figures are 2000 MHz with 8 Gbps effective on the AMD part, versus 1313 MHz with 21 Gbps effective on the NVIDIA part.

Feature sets also differ in availability. The MI350X lists no RT cores, no tensor cores, and its API support is marked as N/A for DirectX, OpenGL, and Vulkan. The RTX 4070 AD103 includes 46 RT cores, 184 tensor cores, DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD card offers no display outputs, while the NVIDIA card provides 1x HDMI 2.1 and 3x DisplayPort 1.4a.

Power and physical design separate the two further. The MI350X has a TDP of 1000 W, a suggested PSU of 1400 W, and uses an OAM Module slot width with no power connectors listed. The RTX 4070 AD103 draws 200 W, suggests a 550 W PSU, is dual-slot, and uses a single 16-pin connector. The AMD module measures 102 mm in length and 165 mm in width. The NVIDIA card measures 240 mm in length, 110 mm in height, and 40 mm in width.

Where Each One Wins

The MI350X dominates in compute-heavy workloads that scale with FP32 or FP16 throughput. Its 72.09 TFLOPS in both precisions, 2,252.8 GTexel/s texture rate, and 8.19 TB/s memory bandwidth position it for large matrix operations, data center inference, and scientific simulation. The 288 GB memory capacity allows datasets far larger than what the 12 GB RTX 4070 AD103 can hold locally. The PCIe 5.0 x16 interface on the AMD part gives it twice the link generation of the NVIDIA card's PCIe 4.0 x16.

The RTX 4070 AD103 wins in graphics-oriented workloads. Its 64 ROPs and 158.4 GPixel/s pixel rate enable traditional rasterization output that the MI350X cannot perform, since the AMD part is listed at 0 MPixel/s with no ROPs. The NVIDIA card also brings RT cores, tensor cores, and a full graphics API stack, which the MI350X lacks entirely. Display outputs on the RTX 4070 AD103 allow direct monitor connection, while the MI350X has none.

Clock speed favors the RTX 4070 AD103 in frequency-sensitive tasks. Its base clock of 1920 MHz and boost of 2475 MHz exceed the MI350X's 1000 MHz base and 2200 MHz boost. However, the MI350X compensates through sheer resource count, with nearly three times the shading units and over five times the TMUs.

Thermal and power constraints also separate use cases. The RTX 4070 AD103's 200 W TDP and 550 W suggested PSU fit conventional desktop builds. The MI350X's 1000 W TDP and 1400 W suggested PSU demand server infrastructure. The NVIDIA card's end-of-life production status suggests replacement by the GeForce 50 series, while the MI350X has no successor listed.

The Verdict

The data indicates two products built for entirely different roles. The AMD Instinct MI350X is a compute accelerator with no graphics pipeline, no display outputs, and no consumer API support. Its 288 GB HBM3e memory, 8.19 TB/s bandwidth, and 72.09 TFLOPS in FP32 and FP16 make it a server-class device for memory-bound and throughput-bound workloads. The RTX 4070 AD103 is a consumer graphics card with a full API stack, RT cores, tensor cores, display outputs, and a much lower 200 W TDP.

Anyone needing pixel output, ray tracing, or standard graphics APIs should select the RTX 4070 AD103. It is the only option of the two with ROPs, a pixel rate of 158.4 GPixel/s, and Vulkan 1.4 support. Its 599 USD launch MSRP places it in the consumer market, and its end-of-life status indicates it sits at the end of its product cycle.

Anyone needing maximum memory capacity, memory bandwidth, or raw FP32 and FP16 throughput should select the MI350X. The 16.24 times bandwidth advantage and 24 times capacity advantage cannot be offset by the NVIDIA card's higher clocks. The 1000 W TDP and 1400 W suggested PSU require data center infrastructure, but the recorded specifications show no consumer alternative with comparable memory resources. The choice follows the workload, not the raw score.
