AMD Confirms Radeon RX 7900 Series Clocks, Direct Competition with RTX 4080
AMD in its technical presentation confirmed the reference clock speeds of the Radeon RX 7900 XTX and RX 7900 XT RDNA3 graphics cards. The company also made its first reference to a GeForce RTX 40-series "Ada" product, the RTX 4080 (16 GB), which is going to launch later today. The RX 7900 XTX maxes out the "Navi 31" silicon, featuring all 96 RDNA3 compute units or 6,144 stream processors; while the RX 7900 XT is configured with 84 compute units, or 5,376 stream processors. The two cards also differ with memory configuration. While the RX 7900 XTX gets 24 GB of 20 Gbps GDDR6 across a 384-bit memory interface (960 GB/s); the RX 7900 XT gets 20 GB of 20 Gbps GDDR6 across 320-bit (800 GB/s).
The RX 7900 XTX comes with a Game Clocks frequency of 2300 MHz, and 2500 MHz boost clocks, whereas the RX 7900 XT comes with 2000 MHz Game Clocks, and 2400 MHz boost clocks. The Game Clocks frequency is more relevant between the two. AMD achieves 20 GB memory on the RX 7900 XT by using ten 16 Gbit GDDR6 memory chips across a 320-bit wide memory bus created by disabling one of the six 64-bit MCDs, which also subtracts 16 MB from the GPU's 96 MB Infinity Cache memory, leaving the RX 7900 XT with 80 MB of it. The slide describing the specs of the two cards compares them to the GeForce RTX 4080, which is what the two could compete more against, especially given their pricing. The RX 7900 XTX is 16% cheaper than the RTX 4080, and the RX 7900 XT is 25% cheaper.

To be fair you did it right. I know DDR5 is still a bit expensive but for such a CPU ddr4 is a waste of performance. DDR5 is the only way.
for a GPU you can use a used card or is that not your thing?
If I was still using 1440p I'd probably keep my 1080 for a while longer, but now I want to play at 4k preferably at 60-120 fps without breaking the bank since cards have more than doubled in price since I last bought one lol
Heck, we used to be good with pen&paper :)
I still am...
I really wonder what this whole evolution of games in the digital space is like if you haven't seen it grow naturally into games. I mean, lots of concepts we have in gaming originate from simple board games and stuff like the above D&D. The whole RPG-lite we have today... came straight from tabletop. Lots of recent games also try to move 'back to tabletop experiences', mostly turn-based strategy and stuff like that, being essentially digital games of chess with many more layers on top. Look at the continuous succcess of Total War Warhammer; it works because it really does mimic the tabletop experience in a fantastic way, even adding progression to your army build in the campaign. In that sense, its easy to understand the renaissance of 'old games' lately, and why they work, its like opening back up to games that are so much closer to the 'source' than all of their sequels.
And it happens vice versa. A card game like Munchkin actively takes digital-inspired roleplay elements and progression ideas and runs with it; gear up, smash monsters. When you can decouple the game from the visual aspect, a whole world opens up indeed ;)
I had an argument with a friend about gaming not long ago. I started it by saying that TV series and movies from big Hollywood studios are all the same crap nowadays. His (strawman) counter-argument was that games are all the same - you just kill things, sometimes with guns, sometimes with swords, etc. Then I sent him links for the trailers of Abzu, Deliver us the Moon, Spintires, The Last Tree, Cities: Skylines, Ori and the Blind Forest, and Stray and asked him to show me the part where you kill things. This argument made me realize how versatile gaming really is, especially when you compare it to films and TV series that come from a handful of studios, sharing the same view and message. AAA titles easily disappoint, just like Hollywood blockbusters do, but we, gamers, at least have a wide variety of choice. :)
This likely happens because a lot of "hardware RT" is actually good old shader code. (preparing/maintaining BTG structure etc)You mean, given that 7900XTX is faster than 3090Ti at RT? :D
Yeah. Will struggle, of course.
But you can always buy a 2060 or 3050 as a spare card to play RT games. While it will be several times slower than on the latest AMD cards, you will get more features, such as fancy DLSS upscaling sprinkled with AI and all... :roll:
The meta review had the 3090Ti at 83.2% of the 4080 in 4K RT performance.
AMDs slides showed that the geomean gain for the 7900XTX over the 6950XT in RT was 66% so applying that to the 6950XT 52.9% average in the meta review puts the 7900XTX at around 87.8% of a 4080.
Funnily enough that means the $1,000 price tag is about inline with the RT performance scaling because the 4080 MSRP give you $12 per index point and the 7900XTX is $11.39
Just let this sink in: RX 6800 XT is closer in performance to the RX 6900 XT than the RX 7900 XT is to the RX 7900 XTX(acording to amd own slides). Think about it really hard xD. THe price of the 7900 XT should be $650 MAX.
they did the same thing with 6900XT , RUSHING the production , release a fonctionnal GPU and do the real thing after.
