Both graphics cards use NVIDIA’s Ada Lovelace design, which came out at the end of the third quarter 2022. But there is a slight change in how the GPUs are set up. The RTX 4080 has the AD103 GPU, while the RTX 4090 has the AD102 GPU. Does that change things a lot? The answer is yes, regarding how far your graphics card can go.

AD102’s higher configurations make it the best GPU. Compared to AD102’s 608 mm2, AD103’s die size is 378.6 mm2. AD102 has more transistors than AD103. The RTX 4080 has 45,900 million transistors, whereas the RTX 4090 has 76,300 million.

Other than configurations, the two cards share the same architecture. Remember that they were launched simultaneously but for distinct audiences.

Clock Speeds And Memory

Because memory type, size, and clock rates affect graphics card performance, this is another crucial factor to consider when selecting a card. In this way, these two cards play on distinct levels.

The base and boost clocks are similar, with the RTX 4080 having a base frequency of 2205 MHz and the 4090 2235 MHz. The RTX 4080 and 4090 boost clock speeds are 2505 MHz and 2520 MHz, respectively.

Memory type, size, and speed distinguish the cards. The RTX 4090 has 24 GB of RAM, while the 4080 has 16 GB. Both contain GDDR6X memory; however, the RTX 4090’s 384-bit BUS width is roughly 50% faster than the 4080’s 256-bit.

A faster BUS and higher transmission rates make the RTX 4090 GPU powerful. The RTX 4080’s memory bandwidth is 716.8 GB/s, whereas it is 1008 GB/s.

AI And Ray Tracing

The RTX 4090 is more powerful but differs in AI and ray tracing. AI-accelerated graphics performance is unmatched with 3rd-gen DLSS and 4th-gen tensor cores. Both 4000 NVIDIA cards have Optical Flow Acceleration. Machine learning and AI augmentation will raise FPS when gaming on your GPUs.

As said, their configuration differs. The RTX 4080 has 304 tensor cores, but the 4090 has 512 tensor cores. The RTX 4080 has 76 3rd-gen RT cores, whereas the 4090 has 128 of those cores. 


NVIDIA carefully designed the RTX 4080 and 4090. Both cards use the 30-series dual-fan design. The RTX 4080 is bulkier than the 4090.

RTX 4080 is 0.2 inches longer than RTX 4090. It’s also 5.5 inches wider than the RTX 4090’s 5.4 inches. The cards are the same height. Their designs are comparable to NVIDIA’s 3080 Ti graphics card, but the RTX 4080 and 4090’s cooling fans are more extensive, indicating that the business has focused on cooling.
