*** The AMD RDNA 4 Rumour Mill ***

That's because the 4070 doesn't have the power to sustain a minimum of 60fps pre-FG (DLSS3), so the input latency is considerably higher and the experience is poorer. A minimum of a 4080 is necessary to mitigate this which would then result in a 60fps baseline at 1440p when path tracing, so a post-FG framerate of 90+ and input latency that's actually acceptable but not 100% perfect. Only a 4090 or above is capable of fully acceptable input latency with FG enabled on a path traced game at 1440p - That is of course unless DLSS upscaling is set to Performance. Before dll version 3.7, Performance mode at 1440p would introduce some signs of distance shimmering on specular highlights, this may not be the case any more but I haven't personally checked for this yet.

So if that 4070 can use DLSS Performance with tweaked settings and then get at least 60fps in CP with PT/RR (DLSS 3.5) enabled then the post-FG experience should be mostly excellent. Assuming dll version 3.7 is being used for FG, Upscaling and now RR (3.5) too.

The 4070 is the 1080p RTX solution, 4080@1440p, 4090@@k is the daddy

We've already discussed this somewhere when I pointed that your RTX experience is not representative of 407/ti/80(s) capabilities some time back as other 407/ti/80 users were claiming all sorts of omg FG fps is a gamechanger@1440p/4K and explained why-when it clearly can't in my son and my experience with the 4070*.



*Technically my 4070 can hit PT'ing@ 1440p but it's scene dependant so it isn't consistent enough for a smooth experience when the fps plummet.:)

Have we ,how many posts have you rtm’ed. Each thread gets opposing views and it is a fine balance between deleting and letting it run its course.

Some of us don't bother RTM, but as @eeii and others have pointed out it's the RDNA 4 Rumour Mill, it's turned into another @mrks modded CP Screenshot YT thread.:p

It depends what you're used to and what you can tolerate.

AMD Radeon RX 8000 (RDNA4) GPUs rumored to use 18 Gbps GDDR6 memory - VideoCardz.com

Radeon RX 8000 rumors point towards slower GDDR6 memory According to respected hardware leaker Kepler_L2, the RDNA4 generation may be sticking to slower memory. Kepler was among the first to reveal that AMD is scrapping its plans for big Navi4 GPUs, and this information is slowly being...

RDNA4 GPUs RX 8600 and RX 8700 will not feature GDDR7 but it will use same 18 Gbps GDDR6 memory featured on both RDNA3 GPUs RX 7600 and RX 7700.

Nvidia Blackwell RTX 5000 will be the only one that will use next generation GDDR7 memory.

18 GB/s? I get sticking with GDDR6 for now but 18 GB/s? up it to 21 if not 23, even the 7800 XT comes with 20 GB/s IC's.
 
that's being the point since rdna3, put budget into cache, and due to extra cache, get savings by using slow vram.

AMD must believe they can achieve the same performance with a lower cost by having cache with cheap memory

Not even the advantage of beating Nvidia in release schedule with the mid-range. How can they be even MORE pathetic than the RDNA 3 release? Sigh.

It's not that I expected them to hustle and do much in the first place but in this way they just gave up entirely on dGPU until at least 2026 (more like 2028). At that point it's still no more than a meagre hope that what they will have prepped for next-gen consoles will be competitive and Nvidia won't slap them even further into irrelevance. Hell, they're even giving Intel space & time to catch up.

I just don't understand how the Radeon division is only ever getting worse and today they don't even have the looming threat of bankruptcy and extremely limited resources to excuse this poor performance. Luckily for them at least that Nvidia can only see this development and think: time to push profit margins to 80% on desktop; just sell them scraps.

Honestly, it feels like they are trying to see what price gauging they can get away with.
 
My guess is that RTG is the poorest performing when it comes to profit overall within AMD, and the piece of the pie AMD is allocated in regards to chip production they have to play it smart and give priority to the segments that make the most. Wouldn't surprise me to see AMD just produce mid-range and lower-end dGPU's from now onwards...
