Nvidia announced the next generation of its graphics cards and also released three new cards based on its next generation graphics architecture. The new RTX 40 series is officially here, and it starts at €899 or Rs 72,000 converted.
At the top of the stack is the new RTX 4090. This massive new GPU features 16384 CUDA cores with boosted clocks of up to 2.52 GHz. The card comes with 24GB of GDDR6X memory and a 384-bit memory interface. Nvidia claims it’s 2-4x faster than the RTX 3090 Ti. The RTX 4090 is rated at 450W and operates on a single 16-pin PCIe Gen 5 cable or 3 x 8-pin PCIe cables. It is priced at €1,599 or Rs 1.28,000 converted and will be available from October 12.
Then we have the RTX 4080, which comes in two variants. The most premium variant features 9728 CUDA cores and a boost clock of 2.51 GHz. It has 16 GB of GDDR6X memory with a 256-bit interface. Nvidia claims it’s 2-4x faster than the RTX 3080 Ti.
Then there is also a second variant with 12 GB of GDDR6X memory and a 192-bit memory interface. This version has 7680 CUDA cores and a boost clock of 2.61 GHz.
The 16GB model is rated at 320W and the 12GB at 285W. They are priced at €1,199 or Rs 96,000 converted and €899 or Rs 72,000 converted respectively and will be available in November.
At the heart of these new graphics cards is the new GPU. Based on Nvidia’s new TSMC 4nm Ada Lovelace architecture, the new GPU includes 3rd Gen RT Cores, 4th Gen Tensor Cores, and support for new features such as DLSS 3 and AV1 encoder.
Compared to the 40 shaders-TFLOPs of the RTX 3090 Ti, the RTX 4090 has 83-TFLOPS. Thanks to the new revamp of shader execution, shader performance is said to improve by 2x and in-game frame rates by 25%. Nvidia also claims that RT performance on the RTX 4090 is around 191-TFLOPS while the RTX 3090 Ti was capable of 78-TFLOPS. The new 4th Gen Tensor Cores are said to have 5x throughput on the RTX 4090.
One of the most impactful features announced was DLSS 3, which will be exclusive to 40-series graphics cards. The new version uses an optical flow accelerator and data from sequential frames to create new frames on the GPU itself. -same (rather than in-game) to improve frame rates up to 4x. This method also bypasses all CPU bottlenecks that plague traditional methods of oversampling and image reconstruction as the frame rate increases.
The new 40-series models will replace the 3090 series of cards but will join the existing 3060, 3070, and 3080 series of cards, which will continue to be sold until at least 2023. Lower variants of the 40-series, such as the 4060 and the 4070 will be much cheaper but vastly improved over existing 30-series cards.
Nvidia will sell its own Founders Edition cards for the 16GB RTX 4090 and RTX 4080, alongside models from AIB partners, such as Asus, Colorful, Gainward, Galaxy, Gigabyte, Inno3D, MSI, Palit, PNY, and Zotac. Most of these cards feature a 3- or 4-slot design as well as large power requirements. The cards will have HDMI 2.1 and DisplayPort 1.4 connectivity.
