Introduction
Selecting a brand new graphics card is all the time a sophisticated enterprise. On the one hand all of us need the quickest, shiniest, most succesful graphics card round, however on the opposite we have all bought fiscal limitations that make shopping for the one you desire a uncommon occurance.
The first deciding issue, past cash, is what you truly plan to do with it. It behoves you to be sincere with your self on this division, because it can’t solely prevent cash in the long term, but additionally go away you extra fulfilled. The massive two producers have all the time produced playing cards which goal a selected section of the viewers, and the newest two additions to the AMD Radeon 7000 vary are not any exception. There’s the RX 7700 XT which is geared toward these of you who sport at 1440 or 1080, and the RX 7800 XT which can also be 1440/1080 based mostly, however with a bit extra oomph for under a bit additional money.
While AMD themselves do not do a model of the RX 7700 XT – examine our XFX overview additionally going dwell at the moment – each playing cards are so equally featured and priced that their audience is similar. What actually separates them, and is probably key to pondering of them as an idea, is the additional structure occurring below the hood. We observe the market intently and we’re conscious that many individuals have chosen to speculate, even now, in a 6000 collection Radeon card as a approach of attempting to maximise their value per efficiency reward.
With a value level under £500 for each playing cards, the inclusion of AI Accelerators, and far greater fill-rates than the 6000 playing cards, you owe it to your self to get on board the RDNA 3 prepare. Greater than nearly every other {hardware}, the architectural adjustments of the newest graphic card generations deliver advantages that uncooked horsepower can not match, and it is best to all the time personal the latest model when you’re searching for an improve. All of which is okay, however everyone knows the actual acid take a look at is how effectively they carry out in video games. Fear not, we’ll come to our take a look at outcomes quickly, and we’re positive that these of you who’ve been eager on a RX 6800 will probably be pleasantly shocked.
Technical Specs
Though AMD are solely producing their very own RX 7800 XT playing cards, and you have to go to the distributors to get a RX 7700 XT, we thought it was attention-grabbing how intently matched the 2 playing cards are, and positively how a lot additional {hardware} horsepower they’ve as compared to those who have come earlier than. It is perhaps tempting to avoid wasting just a few kilos and go for an older card, however very similar to the step from the GTX to RTX Nvidia playing cards, the step from RDNA 2 to RDNA 3 is important and totally worthy of your funding.
