AMD Instinct MI350P vs NVIDIA GeForce RTX 4050 Mobile Comparison

Where Each One Wins

The AMD Instinct MI350P and NVIDIA GeForce RTX 4050 Mobile occupy opposite ends of the GPU spectrum. The MI350P is a datacenter compute accelerator with no display outputs, no graphics API support, and no benchmark entries in the database. The RTX 4050 Mobile is an active laptop part with nine recorded benchmark scores and a full graphics API stack. The division of wins is therefore stark: the MI350P records zero benchmark wins, while the RTX 4050 Mobile records zero losses only because the head-to-head benchmark array is empty.

The RTX 4050 Mobile's recorded data comes from Geekbench and Passmark tests. Its highest raw score is 75,235 in Geekbench Vulkan, followed closely by 74,748 in Geekbench OpenCL. Passmark results are more varied: the G3D score reaches 14,423, while G2D sits at 633. Compute-oriented tests show 5,947 in Passmark GPU Compute, with DirectX 9 at 184, DirectX 11 at 130, DirectX 10 at 79, and DirectX 12 at 61. These numbers position the mobile part in the 63rd percentile of all GPUs in the database, with an average benchmark score of 19,049.

For the MI350P, the absence of benchmark data means the database records a 50th percentile placement and an average score of zero. That percentile reflects the lack of measured results rather than a performance judgment. The accelerator's purpose is compute, not graphics, so the absence of DirectX, OpenGL, and Vulkan support aligns with its design. No display outputs further confirm this role.

The use-case split is clear from the data: the RTX 4050 Mobile is for graphics and general compute workloads in portable devices, while the MI350P is for datacenter-scale compute where display and graphics APIs are irrelevant.

Architecture Differences

The two chips share a foundry but diverge in every other architectural respect. Both use TSMC fabrication, but the MI350P is built on a 3 nm process while the RTX 4050 Mobile uses 5 nm. The MI350P's chip is labeled "MI350 128CU" and uses the CDNA 4.0 architecture, belonging to the Instinct (MIx) generation. The RTX 4050 Mobile uses the AD107 chip with Ada Lovelace architecture, part of the GeForce 40 Mobile series.

Transistor counts differ by a factor of nearly four. The MI350P packs 73,000 million transistors on a 1190 mm² die, yielding a density of 61.3M per mm². The RTX 4050 Mobile has 18,900 million transistors on a 159 mm² die, giving a much higher density of 118.9M per mm². The density advantage reflects the smaller, denser design of the laptop chip, while the MI350P's massive die prioritizes raw compute resources.

Memory configurations could not be more different. The MI350P uses 144 GB of HBM3e across an 8192-bit bus, producing 8.19 TB/s of bandwidth. The RTX 4050 Mobile uses 6 GB of GDDR6 on a 96-bit bus with 192.0 GB/s. The memory clock is listed at 2000 MHz for both, with 8 Gbps effective for the MI350P and 16 Gbps effective for the RTX 4050 Mobile.

Compute resources also diverge sharply. The MI350P has 8,192 shading units and 512 texture mapping units, but zero ROPs and a pixel rate of 0 MPixel/s. The RTX 4050 Mobile has 2,560 shading units, 80 TMUs, and 48 ROPs, with a pixel rate of 84.24 GPixel/s. The MI350P has no ray tracing or tensor cores listed, while the RTX 4050 Mobile includes 20 RT cores and 80 tensor cores.

Clock speeds favor the mobile chip. The RTX 4050 Mobile runs at a 1455 MHz base and 1755 MHz boost, while the MI350P runs at 1000 MHz base and 2200 MHz boost. The MI350P's higher boost clock partially compensates for its massive core count, resulting in 36.04 TFLOPS FP32 and FP16 (1:1). The RTX 4050 Mobile delivers 8.986 TFLOPS in both precision formats.

Power and physical design reflect their intended environments. The MI350P draws 600 W, uses a dual-slot cooler, requires a single 16-pin connector, and suggests a 1000 W power supply. It measures 267 mm by 111 mm by 40 mm. The RTX 4050 Mobile is an IGP-class part at 50 W, with no power connectors, no suggested PSU, and dimensions dependent on the portable device. The MI350P uses PCIe 5.0 x16, while the RTX 4050 Mobile uses PCIe 4.0 x8.

API support separates them completely. The MI350P lists N/A for DirectX, OpenGL, and Vulkan. The RTX 4050 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for this pair, and the MI350P has no individual benchmark scores at all. The only measured performance data belongs to the RTX 4050 Mobile. Its Geekbench OpenCL score of 74,748 and Vulkan score of 75,235 indicate strong compute and graphics throughput for a mobile part. Passmark G3D at 14,423 places it in the mid-range of the database, while G2D at 633 reflects typical 2D performance.

The RTX 4050 Mobile's nearest rivals in the database provide context. The AMD Radeon RX 6600 scores 19,036, a delta of 0.1 percent above the RTX 4050 Mobile's average. The NVIDIA Quadro K6000 matches at 19,030, also 0.1 percent higher. The NVIDIA Tesla K20m scores 19,089, which is 0.2 percent lower than the RTX 4050 Mobile. The NVIDIA RTX 2000 Ada Generation scores 18,954, 0.5 percent below. These deltas are all within half a percent, indicating the RTX 4050 Mobile's average score sits in a tight cluster with these four products.

The MI350P cannot be compared on these terms because it has no measured scores. Its architectural specifications, however, show a compute capability that dwarfs the mobile part. The 36.04 TFLOPS FP32 figure is roughly four times the RTX 4050 Mobile's 8.986 TFLOPS. Memory bandwidth of 8.19 TB/s is over 42 times the 192.0 GB/s available to the RTX 4050 Mobile. The MI350P also has 144 GB of memory versus 6 GB, a 24-fold capacity advantage.

Texture rates tell a similar story. The MI350P reaches 1,126.4 GTexel/s, while the RTX 4050 Mobile manages 140.4 GTexel/s. The MI350P's 512 TMUs against 80 TMUs explains most of this gap. Pixel rate goes the other way: the RTX 4050 Mobile produces 84.24 GPixel/s, while the MI350P produces 0 because it has no ROPs.

The release dates in the database place the RTX 4050 Mobile in early 2023, with the MI350P scheduled for mid-2026. The RTX 4050 Mobile's predecessor is the GeForce 30 Mobile series, and its successor is the GeForce 50 Mobile series. The MI350P's predecessor is the Radeon Instinct line, with no successor listed.
