AMD Instinct MI350P vs NVIDIA GeForce RTX 4070 Max-Q Comparison

FAQ

Q: What are the architectural generations of these two processors?

A: The AMD Instinct MI350P uses CDNA 4.0 architecture, while the NVIDIA GeForce RTX 4070 Max-Q is built on Ada Lovelace. The MI350P is part of AMD's Instinct (MIx) generation, and the RTX 4070 Max-Q belongs to the GeForce 40 Mobile series.

Q: How do the memory configurations differ between the two?

A: The MI350P carries 144 GB of HBM3e memory on an 8192-bit bus with 8.19 TB/s bandwidth. The RTX 4070 Max-Q has 8 GB of GDDR6 on a 128-bit bus with 256.0 GB/s bandwidth. The MI350P's memory capacity is 18 times larger, and its bandwidth is roughly 32 times higher.

Q: Which processor has higher raw FP32 compute throughput?

A: The MI350P delivers 36.04 TFLOPS FP32, compared to 11.34 TFLOPS for the RTX 4070 Max-Q. The AMD part is approximately 3.2 times higher in FP32 performance.

Q: What is the power envelope of each processor?

A: The MI350P has a TDP of 600 W and requires a 1000 W suggested PSU with a 1x 16-pin power connector. The RTX 4070 Max-Q has a TDP of 35 W and uses no power connectors, being an integrated graphics package.

Q: Do both processors support standard graphics APIs?

A: No. The MI350P lists DirectX, OpenGL, and Vulkan as N/A. The RTX 4070 Max-Q supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Q: What are the physical form factors?

A: The MI350P is a dual-slot card measuring 267 mm in length, 111 mm in height, and 40 mm in width, with no display outputs. The RTX 4070 Max-Q is an IGP (integrated graphics processor) with no listed dimensions and portable-device-dependent display outputs.

Architecture Differences

The AMD Instinct MI350P is built on TSMC's 3 nm process node and contains 73,000 million transistors on a 1190 mm² die, yielding a transistor density of 61.3M per mm². It uses a chip labeled MI350 128CU, indicating a 128 compute unit design. The architecture is CDNA 4.0, which is AMD's compute-optimized line, and it features 8192 shading units, 512 texture mapping units, and 0 ROPs. The pixel rate is recorded as 0 MPixel/s, consistent with a part that has no display outputs and is not designed for rasterization. The texture rate is 1,126.4 GTexel/s, and FP16 performance is identical to FP32 at 36.04 TFLOPS (1:1).

The NVIDIA GeForce RTX 4070 Max-Q uses TSMC's 5 nm process node with 22,900 million transistors on a 188 mm² die, giving a transistor density of 121.8M per mm². The chip is AD106, part of the Ada Lovelace architecture. It has 4608 shading units, 144 TMUs, 48 ROPs, 36 ray tracing cores, and 144 tensor cores. The pixel rate is 59.04 GPixel/s, and the texture rate is 177.1 GTexel/s. FP16 is again 1:1 with FP32 at 11.34 TFLOPS.

The fundamental split is compute versus graphics. The MI350P strips out display and rasterization hardware entirely, while the RTX 4070 Max-Q includes ray tracing cores, tensor cores, and a full graphics pipeline with DirectX 12 Ultimate support. The MI350P's transistor count is about 3.2 times higher, and its die is roughly 6.3 times larger. The RTX 4070 Max-Q uses a denser process layout, however, packing more transistors per square millimeter.

Clock behavior differs sharply. The MI350P has a base clock of 1000 MHz and a boost of 2200 MHz. The RTX 4070 Max-Q runs a 735 MHz base and 1230 MHz boost, reflecting its low-power mobile design. The MI350P's memory clock is listed as 2000 MHz with 8 Gbps effective, while the RTX 4070 Max-Q also uses a 2000 MHz memory clock but with 16 Gbps effective.

Where Each One Wins

The MI350P wins in any scenario demanding massive memory capacity or extreme bandwidth. Its 144 GB HBM3e pool and 8.19 TB/s bandwidth serve workloads that hold large datasets on-chip, such as large model inference or high-performance computing tasks. The 8192-bit bus width is the enabler here, and the FP32 throughput of 36.04 TFLOPS gives it a clear edge in dense compute. The 1:1 FP16 ratio also means half-precision workloads run at the same 36.04 TFLOPS, which suits compute tasks that mix precision levels.

The RTX 4070 Max-Q wins in graphics and mobile integration. It has 48 ROPs and a 59.04 GPixel/s pixel rate, so it can drive displays, while the MI350P has no display outputs at all. The 36 ray tracing cores and 144 tensor cores give it hardware support for ray-traced rendering and AI-accelerated graphics features. Its 35 W TDP and IGP form factor let it operate in portable devices without external power connectors. The MI350P requires a 600 W TDP and a 1000 W suggested PSU, which places it firmly in server or workstation installations.

The RTX 4070 Max-Q also wins on API compatibility. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI350P lists N/A for all three, so it is not suited to gaming or general graphics applications. The PCIe interface also differs: the MI350P uses PCIe 5.0 x16, while the RTX 4070 Max-Q uses PCIe 4.0 x8, which is more typical of a mobile part.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark scores between these two parts, and both have an average benchmark score of 0 with a 50th percentile ranking across all GPUs. The comparison therefore rests on the specification deltas.

The largest win for the MI350P is memory bandwidth. At 8.19 TB/s, it is roughly 32 times the RTX 4070 Max-Q's 256.0 GB/s. Memory capacity follows a similar pattern: 144 GB versus 8 GB is an 18-fold difference. For workloads that scale with memory size or bandwidth, such as large model training or simulation datasets, the MI350P holds an overwhelming advantage. The 8192-bit bus versus 128-bit bus explains most of this gap.

FP32 compute also favors the MI350P decisively. At 36.04 TFLOPS, it delivers about 3.2 times the RTX 4070 Max-Q's 11.34 TFLOPS. FP16 performance matches the FP32 figures on both parts, so the ratio stays the same in half-precision. The MI350P's texture rate of 1,126.4 GTexel/s is about 6.4 times the RTX 4070 Max-Q's 177.1 GTexel/s, which reflects the much higher TMU count of 512 versus 144.

The RTX 4070 Max-Q wins in pixel throughput. Its 59.04 GPixel/s is meaningful because the MI350P records 0 MPixel/s, a direct consequence of having no ROPs. The NVIDIA part also has 48 ROPs against none, 36 ray tracing cores against none listed, and 144 tensor cores against none listed. These features make the RTX 4070 Max-Q functional as a graphics processor, whereas the MI350P cannot output video at all.

Power efficiency is another clear win for the RTX 4070 Max-Q. Its 35 W TDP is a fraction of the MI350P's 600 W. The MI350P needs a 1000 W suggested PSU and a 16-pin connector, while the RTX 4070 Max-Q draws power from the portable device itself with no external connectors. The mobile part also runs at lower clocks, 735 MHz base and 1230 MHz boost, which keeps thermal output low enough for an IGP form factor.

Process technology splits the two in an interesting way. The RTX 4070 Max-Q has a higher transistor density at 121.8M per mm², despite using a larger 5 nm node. The MI350P's 3 nm node yields 61.3M per mm², but the massive die area of 1190 mm² allows it to pack over three times the total transistors. The MI350P is also newer, with a release date of 2026-05-06, while the RTX 4070 Max-Q launched on 2023-01-02.

The MI350P uses a dual-slot cooler profile and measures 267 mm in length, 111 mm in height, and 40 mm in width. The RTX 4070 Max-Q has no listed dimensions, consistent with an integrated part soldered into a laptop motherboard. The MI350P's PCIe 5.0 x16 interface provides more host bandwidth than the RTX 4070 Max-Q's PCIe 4.0 x8 link, which matters for data transfer in compute servers.

In summary, the recorded data shows two processors designed for opposite ends of the computing spectrum. The MI350P is a high-power, high-memory compute accelerator with no graphics capability. The RTX 4070 Max-Q is a low-power mobile graphics processor with full API support and hardware ray tracing. Each leads in the categories that define its intended use.
