AMD Instinct MI350P vs AMD Radeon RX 7700S Comparison

AMD Instinct MI350P is a data center compute accelerator built on CDNA 4.0, while AMD Radeon RX 7700S is a mobile gaming GPU based on RDNA 3.0. The database shows no overlapping benchmark submissions for these two parts, so the analysis below relies on their recorded specifications, the available benchmark scores for the RX 7700S, and the relative performance of that mobile GPU against its nearest rivals.

Where Each One Wins

The AMD Instinct MI350P wins in raw compute throughput, memory capacity, and memory bandwidth. Its FP32 rate is 36.04 TFLOPS, which is 76% higher than the RX 7700S’s 20.48 TFLOPS. Its FP16 rate is also 36.04 TFLOPS at a 1:1 ratio, while the RX 7700S reaches 40.96 TFLOPS at a 2:1 ratio, meaning the Instinct part sustains full-rate FP16 without the throughput penalty of the mobile chip. The MI350P carries 144 GB of HBM3e memory across an 8192-bit bus, delivering 8.19 TB/s of bandwidth. The RX 7700S has 8 GB of GDDR6 on a 128-bit bus, with 288.0 GB/s. That is a 28.4x difference in memory capacity and a 28.4x difference in bandwidth, so the MI350P is built for workloads that exceed the memory ceiling of a mobile GPU.

The AMD Radeon RX 7700S wins in graphics-oriented features and efficiency. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI350P lists no graphics APIs. The RX 7700S has 32 ray tracing cores and 64 ROPs, producing a pixel rate of 160.0 GPixel/s and a texture rate of 320.0 GTexel/s. The MI350P has 512 TMUs but 0 ROPs and a pixel rate of 0 MPixel/s, so it cannot rasterize frames. The RX 7700S also draws 100 W versus 600 W for the Instinct card, and it runs on a 6 nm node with a 204 mm² die, whereas the MI350P uses a 3 nm node with a 1190 mm² die. The mobile part is the only one of the two with display outputs, listed as portable device dependent, and it is the only one with an active production status.

In the benchmark database, the RX 7700S holds a 78th percentile ranking among all GPUs, with an average benchmark score of 33849. The MI350P has a 50th percentile ranking and an average benchmark score of 0, reflecting the absence of recorded consumer benchmark submissions. The RX 7700S’s closest rivals in the database are the AMD Radeon HD 7950 at 33951 (-0.3%), the AMD Radeon RX 480 at 33997 (-0.4%), the NVIDIA GeForce GTX 1060 5 GB at 33694 (+0.5%), and the NVIDIA RTX A5000 at 33622 (+0.7%). This places the RX 7700S in a performance band around older desktop cards, while the MI350P sits outside that comparison set entirely.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the MI350P and the RX 7700S, but their recorded specifications establish clear performance deltas. The largest gap is in memory bandwidth. The MI350P moves 8.19 TB/s, which is 28.4 times the RX 7700S’s 288.0 GB/s. Memory capacity follows the same ratio at 144 GB versus 8 GB. For data center workloads that stream large datasets, this is the defining difference between the two products.

Compute throughput also favors the Instinct card. FP32 performance is 36.04 TFLOPS versus 20.48 TFLOPS, a 76% advantage. FP16 performance is nominally higher on the RX 7700S at 40.96 TFLOPS, but that figure relies on a 2:1 packed rate, meaning it executes two FP16 operations per clock. The MI350P achieves 36.04 TFLOPS FP16 at a true 1:1 ratio, so its FP16 throughput is not a halved workload. Texture rate favors the MI350P at 1,126.4 GTexel/s versus 320.0 GTexel/s, a 3.5x difference, while pixel rate is the one graphics metric where the RX 7700S wins outright at 160.0 GPixel/s against 0 MPixel/s.

Clock speeds show a different trade-off. The RX 7700S runs at a 1500 MHz base and 2500 MHz boost, with a 2200 MHz game clock. The MI350P runs at a 1000 MHz base and 2200 MHz boost. The mobile chip operates at higher frequencies, but the Instinct card’s massive 8192 shading units, 512 TMUs, and 8192-bit memory bus compensate for the lower clocks. The MI350P has 8192 shading units versus 2048 for the RX 7700S, a 4x difference, and 512 TMUs versus 128, also a 4x difference. The RX 7700S counters with 32 ray tracing cores, a feature the MI350P does not list.

The RX 7700S’s recorded benchmark scores confirm its position relative to older desktop GPUs. Its Geekbench OpenCL score is 62983, its Geekbench Vulkan score is 36380, and its 3DMark Steel Nomad DX12 score is 2185. These results feed into an average score of 33849, which places it 0.3% below the HD 7950 and 0.4% below the RX 480. The MI350P has no equivalent benchmark entries, so its compute advantages are derived from specification data rather than measured workloads.

Specification Differences

Process node and die size separate the two GPUs sharply. The MI350P uses a 3 nm TSMC process with 73,000 million transistors on a 1190 mm² die, giving a transistor density of 61.3M per mm². The RX 7700S uses a 6 nm TSMC process with 13,300 million transistors on a 204 mm² die, giving a density of 65.2M per mm². The Instinct card is 5.5x larger in die area and holds 5.5x more transistors, but the mobile chip achieves a slightly higher transistor density.

Memory configuration differs across every field. The MI350P uses 144 GB of HBM3e with an 8192-bit bus and 8.19 TB/s bandwidth. The RX 7700S uses 8 GB of GDDR6 with a 128-bit bus and 288.0 GB/s bandwidth. Memory clock is 2000 MHz with 8 Gbps effective on the MI350P, while the RX 7700S runs at 2250 MHz with 18 Gbps effective.

Compute unit layout differs by a factor of four in shading units and TMUs. The MI350P has 8192 shading units and 512 TMUs. The RX 7700S has 2048 shading units and 128 TMUs. The RX 7700S has 64 ROPs and 32 ray tracing cores; the MI350P has 0 ROPs and no listed ray tracing cores. Pixel rate is 0 MPixel/s for the MI350P and 160.0 GPixel/s for the RX 7700S. Texture rate is 1,126.4 GTexel/s for the MI350P and 320.0 GTexel/s for the RX 7700S.

Power and physical design also diverge. The MI350P has a 600 W TDP, a dual-slot cooler, a single 16-pin power connector, and a suggested 1000 W power supply. The RX 7700S has a 100 W TDP, an IGP form factor, no power connectors, and no suggested PSU. The MI350P connects via PCIe 5.0 x16, while the RX 7700S uses PCIe 4.0 x16. The MI350P measures 267 mm by 111 mm by 40 mm; the RX 7700S has no recorded dimensions. The MI350P has no display outputs, while the RX 7700S outputs are portable device dependent. Release dates also differ: the MI350P is dated 2026-05-06, and the RX 7700S is dated 2023-01-03.

Architecture Differences

The MI350P is built on CDNA 4.0, AMD’s compute-focused architecture for the Instinct line, with a chip design labeled MI350 128CU. The RX 7700S is built on RDNA 3.0, the graphics architecture for the Radeon RX 7000 series, with a Navi 33 chip and the codename Hotpink Bonefish. These are different architecture families with different priorities: CDNA 4.0 targets data center compute without graphics output, while RDNA 3.0 targets mobile gaming with full rasterization and ray tracing support.

The MI350P belongs to the Instinct (MIx) generation and lists its predecessor as Radeon Instinct. The RX 7700S belongs to the Navi Mobile (RX 7000M) generation and lists its predecessor as Polaris Mobile. The MI350P’s production status is not recorded, while the RX 7700S is marked active. The MI350P has no DirectX, OpenGL, or Vulkan API support, while the RX 7700S supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 7700S’s 32 ray tracing cores are the only hardware ray tracing capability listed in either product’s specification set; the MI350P has no such field populated.

The two architectures also differ in FP16 handling. CDNA 4.0 on the MI350P runs FP16 at a 1:1 ratio with FP32, meaning both reach 36.04 TFLOPS. RDNA 3.0 on the RX 7700S runs FP16 at a 2:1 ratio, reaching 40.96 TFLOPS while FP32 sits at 20.48 TFLOPS. The smaller process node of the MI350P, 3 nm versus 6 nm, enables the larger transistor count and the 8192-bit HBM3e interface. The RX 7700S compensates with higher clock speeds and a smaller die, but its 128-bit memory bus limits bandwidth to 288.0 GB/s, a fraction of the Instinct card’s 8.19 TB/s.
