The RTX 4090, Nvidia’s latest flagship GPU, has been making waves in the gaming community, and for good reasons. Let’s delve into the specifics of this graphics powerhouse.
Design and Build: The RTX 4090, in terms of design, seems to be a continuation of Nvidia’s commitment to robust and efficient GPUs. The Founders Edition 4090 looks similar to its predecessor, the 3090, but with some noticeable changes. The most significant change is the graphics card’s width. While the 3090 measures 52mm wide, the new RTX 4090 is 17% wider at 61mm. Despite this size increase, both models weigh approximately the same at 2190 grams. Another notable change is the absence of the NVLink connector, which Nvidia has now phased out, relying instead on the PCIe 4.0 bus.
Performance: The RTX 4090 is built on the AD102 silicon, which is about 3% smaller than the GA102 used by the RTX 3080 and 3090. Nvidia transitioned from the Samsung 8N process with Ampere to TSMC’s 4N process for Ada Lovelace. This change resulted in a staggering 170% increase in the transistor count, from 28.3 billion to a whopping 76.3 billion. When compared to the RTX 3090 Ti, the RTX 4090 boasts 52% more streaming multiprocessors, CUDA cores, Tensor cores, RT cores, and texture units. The ROP count has also increased by 57%, and the boost clock has been amped up by 35%. The GPU continues to use the same 21 Gbps GDDR6X memory, with 24GB of it on a 384-bit wide memory bus, resulting in the same 1008 GB/s of memory bandwidth.
Power and Temperature: The RTX 4090 has a total graphics power rating of 450 watts, similar to the 3090 Ti. However, the maximum GPU temperature has been slightly reduced from 93C to 90C. The minimum power supply requirement for the RTX 4090 is 850 watts. One significant change is the 16-pin power input, which has been upgraded to the PCIe 5.0 spec, known as the super catch 12VHPWR power connector. This single PCIe 5.0 power connector can deliver up to 600 watts, which previously would have required four 8-pin power connectors.
Gaming Performance: The RTX 4090 is a game-changer for 4K gaming. With Nvidia’s latest update to its Deep Learning Super Sampling (DLSS), the RTX 4090 can deliver unparalleled 4K performance in games like Cyberpunk 2077, reaching nearly 140fps at 4K with all settings maxed out. At 1440p, the performance is equally impressive, nearly hitting the limit of a 240Hz monitor.
Price: The RTX 4090 comes with a premium price tag of $1,599. While this places it at the top end of the GPU market, the performance it offers justifies the cost for those seeking the best gaming experience.
Conclusion: The Nvidia GeForce RTX 4090 is a testament to Nvidia’s commitment to pushing the boundaries of PC gaming. It offers unparalleled performance, especially at 4K resolutions, making it a must-have for gamers and professionals seeking the best graphical experience. However, the premium price tag and power requirements might be a consideration for some potential buyers.
