The RTX 4080 is based on Nvidia’s Ada Lovelace architecture. It features 9,728 cores with base / boost clocks of 2.2 / 2.5 GHz, 16 GB of memory, a 256-bit memory bus, 76 3rd gen RT cores, 304 4th gen Tensor cores, DLSS 3 and a TDP of 320W. Performance gains will vary depending on the specific game and resolution. With a 4080 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 4080 will show increasing improvements compared to lesser cards. When fps are not CPU bottlenecked at all, such as during GPU benchmarks, the 4080 is around 50% faster than the 3080 and 25% faster than the 3090-Ti, these figures are approximate upper bounds for in-game fps improvements. The 4080 has an MSRP of $1,200 USD. Since PC gamers rarely buy AMD GPUs, Nvidia only have themselves to compete with. AMD continue to burn their credibility with PC gamers. Following a series of over-hyped releases which were heavily promoted on youtube, forums, reddit and twitter, consumers have little interest in the Radeon brand. As time goes on, AMD’s “Advanced Marketing” has a decreasing impact on consumers. Meanwhile, Nvidia remains focused on novel goals such as better graphics (RT/DLSS), frame consistency, game compatibility and driver stability. Consumers looking for better value 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).

The Radeon RX Vega 56 is the weakest member of AMD's Vega GPU family. The Vega architecture is built on 14 nm silicon and contains next-generation compute units (nCUs). Each NCU houses 64 steam processors, of which the Vega 56 has 3584 vs. 4096 in the Vega 64. The new architecture employs 8GB of second generation high-bandwidth memory (HBM2). In terms of compatibility all of the games we tested were fine apart from GTAV where enabling reflection MSAA resulted in very poor, almost matt, reflection fidelity (the same bug appeared on several Navi and Vega cards). Although the Vega 56 has 12.5% less processing units, users have found that by flashing an RX 64 BIOS into an RX 56 card allows a 10% increase in OC headroom which effectively brings a BIOS flashed RX 56 onto par with a stock RX 64 and just 12.5% slower than a fully overclocked RX 64. All of this OC headroom is great on paper but in the real world the reference Vega 56 is far too noisy. Hair dryer levels of noise at stock clocks are unacceptable for most users. Provided you are partially deaf or happy to use noise canceling headphones the Vega 56 “can” deliver levels of performance that approach an RTX 2060 but prices need to drop below $200 before the Vega 56 is competitive.
