       | Well, the article is a bit of a mess.
       | 
       | ... so, what exactly makes it ambitious?
       | 
       | The article itself brands AMD as afterthoughts in "GPU" (note:
       | virtually no references to actual graphics, I get it, AI pushes
       | all the investment these days), and then plops down performance
       | graphs that generally show AMD to be better.
       | 
       | It talks about "compromised" gaming as the stated bar in the
       | opening paragraph.
       | 
       | I understand that Intel has shown near-complete managerial
       | incompetence in discrete graphics despite trying every five years
       | or so. So maybe "not totally failing" is "ambitious".
       | 
       | Maybe at some point, GPUs are "good enough", once you can 4k
       | 120FPS enough aa textured triangles, it's more about art design,
       | modelling, etc (something I actually think AI will be really
       | beneficial for)
       | 
       | Alas the tantalizing prospect of real time raytracing seems to be
       | backburnered under the AI hype onslaught.
       | 
       | So maybe the "lesser" iGPU will be a new sweet spot for a couple
       | generations. Maybe having all the high end cards swooped up for
       | LLM training will have the PC gaming market take a breather and
       | work on optimizing for a somewhat stable hardware capability.

         | 
         | Can you elaborate on this? Is that because ray tracing needs
         | only simple vector units, while AI is driving tensor-type
         | architectures?

           | Not OP, but to provide some historical perspective, RTX

           | the way of PhysX, 3D Vision, and EAX audio. Cool, but
           | complicated and not worth the effort to game devs. Game
           | designers have to make all the lighting twice to fully
           | implement RT, and it's just not worth the effort to them.
           | 
           | Nvidia's own site[1] lists a total of 8 Full RT compatible
           | games, half of which they themselves helped port. There are
           | far more games that "use" it, but only in additional to
           | traditional lighting at the same time to minimize dev costs.
           | Based on that and past trends, I would personally predict it
           | to be dropped after a generation or two unless they can reuse
           | the RT cores for something else and keep it around as a
           | vestigial feature.

             | "Full RT" means the game uses 100% raytracing for rendering
             | (in some mode), which currently needs still far too much
             | power to be a mainstream thing and is only added in a few
             | games to show the prowess of the engine (IIRC a review of
             | the Cyberpunk 2077 Full RT mode only a 4090 is really able
             | to provide the power needed). The important entry is "yes",
             | which shows far more entries and means there's Raytracing
             | enhancements in addition to rasterization.
             | 
             | So, no, it's quite the opposite of what you stated: RT gets
             | more important all the time, is not a gimmick and there's
             | zero reason to assume it will be dropped in the future.

               | It is a gimmick in that you have to sacrifice far too

               | 
               | No thank you, I'll take buttery smooth real 120 FPS at
               | 4K. Especially because games have gotten so good at
               | faking good lighting.

         | "what exactly makes it ambitious?" I thought I outlined that it
         | was much more powerful than Intel's prior (RPL) iGPUs both in
         | the first paragraph, and in the conclusion. It competes with
         | the powerful iGPUs AMD has been getting into handhelds.
         | 
         | "AMD as afterthoughts" - Can you explain how you got that
         | impression? I opened by noting how AMD's APUs are extremely
         | competitive if not downright dominant in handhelds (Steam Deck
         | and ROG Ally called out as specific examples) and threatens
         | Intel in the laptop scene too.
         | 
         | "4K 120 FPS" - uh no, you're not getting that on an iGPU unless
         | it's a game from 15 years ago. I suggest checking the very wide
         | variety of other reviewers who run game benchmarks on devices
         | like the Steam Deck or ROG Ally. 1080P or 720P 30 FPS is a good
         | target, and you might need medium or low graphics to get there.
         | That's what I mean by compromised gaming. It's not the same
         | experience as say, gaming on a desktop with a midrange discrete
         | card.
         | 
         | "lesser" iGPUs imo aren't a new sweet spot, the sweet spot is
         | just holding on to older cards that still deliver better
         | performance than these iGPUs. For example check Steam's
         | hardware survey
         | (https://store.steampowered.com/hwsurvey/videocard/). There are
         | more people with a GTX 1080 than a RTX 4080. And PC games _are_
         | optimizing for stable hardware capability. The latest games are
         | usually playable on Pascal.

           | Well, 4k 120 from an iGPU ... you're saying THAT is

           | 
           | So if I hear Intel being "ambitious" and then read an article
           | that basically pretends (I'm not accusing you of anything)

           | so massively failed/squandered opportunity at smartphone
           | chips, SSDs, memory, graphics, and then finally screwed the
           | pooch in process tech and CPUs. So clearly an engineering
           | company that was hijacked by finance MBAs are driven into the
           | ground, and it is _HARD_ for companies to come back from that
           | poison, especially when they had about 30 years of near-
           | unchallenged monopoly dominance in the marketplace.
           | 
           | I didn't want to imply "author sux Lol" the article was
           | pretty in-depth and information depth, but it remains the
           | basic premise is flawed, because the source marketing/press
