The RTX 4090 is based on Nvidia’s Ada Lovelace architecture. It features 16,384 cores with base / boost clocks of 2.2 / 2.5 GHz, 24 GB of memory, a 384-bit memory bus, 128 3rd gen RT cores, 512 4th gen Tensor cores, DLSS 3 and a TDP of 450W. Performance gains will vary depending on the specific game and resolution. With a 4090 tier card 1080p in-game fps will often get CPU bottlenecked which prevents the GPU from delivering higher fps.
At higher (often sub-optimal) resolutions (1440p, 4K etc) the 4090 will show increasing improvements compared to lesser cards. When fps are not CPU bottlenecked at all, such as during GPU benchmarks, the
4090 is around 75% faster than the 3090 and
60% faster than the 3090-Ti, these figures are approximate upper bounds for in-game fps improvements. The fact that the 4090 is currently the fastest performing graphics card available is reflected in its jaw-dropping MSRP of $1,600. Since PC gamers
rarely buy AMD GPUs, Nvidia only have themselves to compete with. Surprisingly, $1,600 is actually reasonable value for money, when compared to previous gen. flagship cards. Prospective buyers will need a
top of the line system to extract maximum performance from the 4090 and because of its monstrous dimensions, many will also need a new PC case. Consumers that demand value for money, should wait a few more months for the 4060 / 4070 models by which time AMD's 7900 series will also probably be heavily discounted. Alternatively, shoppers looking to buy in the near term should consider the last gen.
3060-Ti, which offers excellent real-world (1080p) performance at a fraction of the price ($400 USD).
