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).

Out of the box the reference 5700 XT has high burst speeds but under load it overheats and therefore drops frames to the extent that it is more or less unusable for demanding games like PUBG. In order to settle the card it was under volted by 120 mV and the maximum clock was lowered to 1,980 MHz (the stock BIOS and 19.9.1 driver defaulted the card to 2,030 MHz). The fan curve also had to be turned up to around 50% power at 75 degrees (which is a lot noisier than stock). After making these changes the card delivered far more consistent performance albeit with a reduced top speed and unacceptable (hair dryer) levels of noise. There were also incompatibilities with GTAV: enabling reflection MSAA resulted in very poor, almost matt, reflection fidelity (the same bug appeared on several Navi and Vega cards). The reference 5700 XT is great for beating cherry picked benchmarks, but it is not so great for playing games. Thousands of people, duped by sponsored marketing material, purchased the reference card expecting flagship performance, instead they got a shopping trolley with a V6 engine. It appears that the same marketing tactics were employed for the reference Vega 56 and 64 series of graphics cards which we will purchase for our gaming lab and generate effective Fps gaming metrics as soon as possible (results here). AMD appear to have very short term marketing strategists at the helm, they seem more concerned with this years bonuses than the longevity of the brand. [Jul '19GPUPro]
