NVIDIA GeForce RTX 4050 Mobile vs NVIDIA GeForce RTX 5090 SE Comparison

Head-to-Head Benchmarks

The recorded data shows a stark contrast between these two NVIDIA mobile and desktop parts, but a direct score-for-score comparison is limited by the available measurements. The RTX 4050 Mobile has a full set of benchmark results, while the RTX 5090 SE currently has no recorded benchmark scores in the database, leaving its performance to be inferred from its specifications alone.

For the RTX 4050 Mobile, the strongest results come from compute-oriented tests. Its Geekbench OpenCL score is 74,748, and its Geekbench Vulkan score is 75,235, placing it in the 63rd percentile of all GPUs tracked. In the Passmark suite, the G3D score of 14,423 is the standout, while the DirectX 9 score of 184 and DirectX 11 score of 130 show legacy API performance. The DirectX 12 score is 61, the DirectX 10 score is 79, and the GPU compute score is 5,947. The 2D score of 633 is comparatively modest. The average benchmark score for the RTX 4050 Mobile is 19,049.

Relative to its nearest rivals, the RTX 4050 Mobile sits in a tight cluster. It is 0.1% ahead of the AMD Radeon RX 6600 and the NVIDIA Quadro K6000, both of which average 19,036. It is 0.5% ahead of the NVIDIA RTX 2000 Ada Generation, which averages 18,954. Against the NVIDIA Tesla K20m, the RTX 4050 Mobile trails by 0.2%, as that card averages 19,089. These deltas are within a fraction of a percent, indicating that the RTX 4050 Mobile's performance is essentially on par with these four cards in aggregate benchmarks.

The RTX 5090 SE, by contrast, has no benchmark entries and no nearest rivals in the database. Its average benchmark score is listed as zero, and its percentile is 50, which reflects the absence of measured data rather than actual performance. This means any head-to-head comparison must rely on architectural and specification differences, not on direct test results. The data available for the RTX 5090 SE is limited to its specifications, release date, and launch MSRP.

Architecture Differences

The two GPUs come from different generations and architectures. The RTX 4050 Mobile uses the AD107 chip built on the Ada Lovelace architecture, part of the GeForce 40 Mobile generation. The RTX 5090 SE uses the GB202 chip built on the Blackwell 2.0 architecture, part of the GeForce 50 generation. Both are manufactured by TSMC on a 5 nm process node, but the transistor counts diverge sharply. The RTX 4050 Mobile packs 18,900 million transistors on a 159 mm² die, giving a transistor density of 118.9 million per mm². The RTX 5090 SE contains 92,200 million transistors on a 750 mm² die, with a density of 122.9 million per mm². The RTX 5090 SE is the larger, denser chip by a substantial margin.

Clock speeds also differ. The RTX 4050 Mobile has a base clock of 1455 MHz and a boost clock of 1755 MHz. The RTX 5090 SE runs at a base clock of 1740 MHz and a boost clock of 2377 MHz. Memory clocks follow the generation split: the RTX 4050 Mobile uses 2000 MHz memory with 16 Gbps effective speed, while the RTX 5090 SE uses 1750 MHz memory with 28 Gbps effective speed.

Memory configuration is another major divider. The RTX 4050 Mobile comes with 6 GB of GDDR6 on a 96-bit bus, delivering 192.0 GB/s of bandwidth. The RTX 5090 SE offers 24 GB of GDDR7 on a 384-bit bus, with 1.34 TB/s of bandwidth. That is a sevenfold increase in capacity and roughly a sevenfold increase in bandwidth.

Compute resources follow the same pattern. The RTX 4050 Mobile has 2560 shading units, 80 texture mapping units, 48 raster output units, 20 ray tracing cores, and 80 tensor cores. The RTX 5090 SE has 14080 shading units, 440 TMUs, 160 ROPs, 110 RT cores, and 440 tensor cores. Pixel rate for the RTX 4050 Mobile is 84.24 GPixel/s, while the RTX 5090 SE reaches 380.3 GPixel/s. Texture rate is 140.4 GTexel/s versus 1,045.9 GTexel/s. FP32 and FP16 performance are both 8.986 TFLOPS on the RTX 4050 Mobile, while the RTX 5090 SE delivers 66.94 TFLOPS in both. The RTX 5090 SE offers roughly 7.4 times the FP32 throughput.

Interface and power delivery differ as well. The RTX 4050 Mobile uses a PCIe 4.0 x8 bus interface, while the RTX 5090 SE uses PCIe 5.0 x16. The RTX 4050 Mobile has no power connectors and is listed as an IGP (integrated graphics package) with a 50 W TDP. The RTX 5090 SE is a dual-slot card requiring a single 16-pin power connector, with a 500 W TDP and a suggested power supply of 900 W. The RTX 5090 SE measures 267 mm in length, 111 mm in height, and 40 mm in width. The RTX 4050 Mobile has no listed dimensions.

Display outputs also differ. The RTX 4050 Mobile's outputs are portable device dependent, while the RTX 5090 SE provides 1x HDMI 2.1b and 3x DisplayPort 2.1b. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data makes the choice straightforward for most users. The RTX 4050 Mobile is a low-power, integrated-class solution for thin-and-light laptops. Its 50 W TDP, absence of power connectors, and portable-dependent display outputs point to a design for mobility and efficiency, not raw performance. Its benchmark results show it performing on par with the AMD Radeon RX 6600 and NVIDIA Quadro K6000, with deltas of only 0.1% in aggregate scoring. That places it in the 63rd percentile of all GPUs, a solid mid-range result for its class.

The RTX 5090 SE is an entirely different product. With a 500 W TDP, dual-slot cooler, 16-pin power connector, and 900 W suggested power supply, it requires a desktop chassis with serious power delivery. Its 24 GB of GDDR7 memory and 1.34 TB/s bandwidth, along with 66.94 TFLOPS of FP32 compute, put it in a performance tier far above the RTX 4050 Mobile. The lack of benchmark scores in the database means its exact position relative to other GPUs cannot yet be confirmed, but its specifications indicate a high-end part aimed at demanding workloads.

For a laptop user who needs an efficient GPU for everyday gaming and productivity, the RTX 4050 Mobile is the only realistic choice given its form factor and power envelope. For a desktop user building a high-performance system, the RTX 5090 SE is the clear pick based on its memory, compute, and bandwidth advantages. The data does not support a single recommendation for both use cases, as the two cards occupy separate segments.

Where Each One Wins

The RTX 4050 Mobile wins in efficiency and portability. Its 50 W TDP is one-tenth of the RTX 5090 SE's 500 W TDP, and it requires no power connectors, making it suitable for integrated laptop designs. Its IGP slot width and portable-dependent display outputs confirm its role in thin, light machines. The benchmark data shows it holding its own against the AMD Radeon RX 6600, NVIDIA Quadro K6000, and NVIDIA Tesla K20m, with aggregate score deltas under 0.5%. For users who need a GPU that fits in a laptop and runs on battery power, the RTX 4050 Mobile is the only option in this comparison.

The RTX 5090 SE wins in every performance-related specification. It has a higher boost clock (2377 MHz vs 1755 MHz), more memory (24 GB vs 6 GB), more bandwidth (1.34 TB/s vs 192.0 GB/s), and roughly 7.4 times the FP32 throughput. Its 14080 shading units, 110 RT cores, and 440 tensor cores dwarf the RTX 4050 Mobile's 2560 shading units, 20 RT cores, and 80 tensor cores. The pixel rate is 380.3 GPixel/s versus 84.24 GPixel/s, and the texture rate is 1,045.9 GTexel/s versus 140.4 GTexel/s. The RTX 5090 SE also supports PCIe 5.0 x16, while the RTX 4050 Mobile is limited to PCIe 4.0 x8. For desktop builds with adequate power delivery, the RTX 5090 SE is the superior part across all measured specifications.
