AMD’s latest, greatest Radeon graphics card $600 cheaper than Nvidia’s top RTX 4090 AMD has come out swinging at Nvidia with new flagship Radeon graphics cards that are cheaper than its rival's fresh GeForce RTX products. Calling its latest products the "world's most advanced" gaming cards, the Silicon Valley-based chip designer said on Thursday that the 24GB Radeon RX 7900 XTX and 20GB Radeon RX 7900 XT will …
New platform, means new drivers, means new bugs to work out - sorta excited at the price to performance (though, obviously, will wait for real world testing to validate) but been burned many a time by ATI's drivers that I will reign in that decision.
At worst, it could mean a bit of price pressure on nVidia cards.
I thought that it will be the compute dies that will be in chiplets, turns out that it's not the case.
It's the cache that is in chiplets, I don't expect much issues from this, or requiring vastly different behaviour from drivers.
Still, will wait for independent benchmarks before pulling the trigger.
The engineer in me thinks: hmm, this is fascinating stuff.
The green but of me thinks: uses a lot of power but it'll save on heating.
The Yorkshireman in me thinks: how much? I'll stick with ex lease laptops, at a fifth of the price...
Obviously I'm not the target market.
--> the nice warm coat, obviously.
Indeed.
I think we were told, way back when color monitors existed and the first high-end graphics cards were born, that 16.8 million is "True Color".
This is the important bit for those who can't follow the link :
"For a display to fool the eye into seeing full colour, 256 shades of red, green and blue are required; that is 8 bits for each of the three primary colours, hence 24 bits in total. However, some graphics cards actually require 32 bits for each pixel to display true colour, due to the way in which they use the video memory – the extra 8 bits generally being used for an alpha channel (transparencies)."
So now I get it. The graphics card is no longer bothering with just 256 shades + transparency. Instead of using 8 bits per RGB value, it is now using 12 bits for every color.
12 bits gives up to 4095 values, raise that to the third power and you get 68 billion.
I doubt the eye is going to see much difference though.
Bravo sir. And now I need a new keyboard.
Re the colour range though: lots of research when TV started using digits suggested that 8 bits for each of red green and blue was sufficient to fool even the critical eye on real world scenes, and that obviously fitted to byte sizes at the time.
But even so, there are certain pathological images which can still show quantization steps; dark blue skies gradually fading are one.
I'm actually more interested in the fans, ever since I had to share an office with a coworker who had a slightly off fan on his videocard ...
it's a bit like Vetinari's clock ... the annoying tick would be regular, and just as you were gettingused to it, the fan would change speed (or whatever it is) and the tick would be different ....
Not really sure, with the advent of Steam Proton support for Linux gaming, I suddenly care to game again 20 years later, but pretty absurd being re-introduced to this when people were scalping gpu's for 3x the cost, ie several thousands of dollars, as apparently they generated gold or something. Suddenly they don't, and I just want some pretty graphics maan, but really - starting at 1000 dollars? I remember buying my first voodoo2 that broke me at $200 bucks, so perhaps I'm jaded.
This card is not a competitor for the 4090 but a competitor for the 4080 and 4080ti.
Rumor has it this card could clock to 3Ghz, some AIBs may bring out cards with 3x 8 pin power connectors.
The race will be interesting, given we all have to tighten our belts I think AMD are going for bang per buck rather
than best performance, but given the chiplett design they could quite easily come out with a faster chip
