crosspost from the predict thread
True but from Sebbi's posts, I mean you dont exactly NEED all your RAM every frame.
And most games will be 30 FPS next gen again, so you can access 2GB per frame with durango.
I can argue the Orbis is over engineered. It can access over 6GB per frame at 30 FPS, yet it's total RAM is only 3.5GB. Now what? Only thing you can do is go back and hit the hard disk or worse, blu ray disk and load more in. Good luck with that.
192 gb/s might be good on pc, where my game might need to go up to anywhere to 200 fps and my resolution up to 4k, but is it good for a console?
In other words over say 3 frames, Durango might be able to do more. It can use 2GB/2GB/1GB of unique data. Orbis will be like 3.5GB/uh-oh/uh-oh
RAM speed is not a substitute for quantity. Both are important.
It actually sounds to me like the PS4 might be really good at 60 FPS games. I mean literally the majority of games might be 60 on it cause it's got so damn much bandwidth. But, they probably wont look much better than 30 FPS Durango counterparts.
For the article, the main thing to come out of it is Orbis using 8 Jag cores supposedly. It was generally thought it would switch to Jag cores by me, but that it's 8 of them and all..
It just removes one more point of differentiation to Durango. However, vs 4 Steamroller cores, it's likely a downgrade realistically.
Also interesting DF says its an SOC and even has a code name. In that case I guess it's true both should be doing SOC's for cost reasons. I was skeptical of SOC's in either, especially PS4, but it's looking more and more likely.
At the end of the day anyway, you may get most multiplatform games optimized for 1.2 teraflops and 3.5GB RAM. Lowest common denominator.
What?
RAM isn't just for reading.
Just look at Xenos Daughter die which has 256GB/s. What for you ask? The peak bandwidth supports the 8 ROPs @ 500MHz uncompressed with 4xMSAA at FP8. Common sense tells you 12 (or 16 or 24 or 32) ROPs at 800MHz is going to require more bandwidth that the 256GB/s Xenos had for Fillrate. Modern GPUs have good compression (hence why we don't need 1TB/s VRAMs) but the point is Fillrate alone can suck up a ton of bandwidth if you want your ROPs to be unfettered by bandwidth stalling your GPU.
As for your PC comment... no, you don't need 192GB/s "just for 200fps". If that were the case PC GPUs could have stopped at 100GB/s (100Hz) and called it a day! No, the problem is FILLRATE can suck up VRAM bandwidth; likewise larger textures, more texture readers, more detailed geometry, etc all take up more VRAM footprint and require more bandwidth to shuffle in and out of the GPU.
Don't believe me? Take a higher end game, throw it on a 7970 or 680 and max out the settings. See it struggle to get close to 60Hz? Now use a GPU app to downclock the GPU memory. Ta da! Watch the framerate drop.
I know you are presenting yourself as a self fashioned "
Durango fanboy defender" but this is starting to sound a LOT like the FUD MS/Sony/ATI/NV reps channeled via PM in these forums in 2005/2006. I mean we have Proelite, getting quoted all over the place, and his punchline is the defense of a shrunk die investment is a closed box system bests the PC so "just wait for the games!" (which is a total PR side step of the point: roll back of silicon budgets).
Oh, and for
giggles:
Those people saying the mainstream rumors are still wrong have a hard time reconciling with lherre.
But I have to roll my eyes because the big specs a couple of you keep PMing me about Iherre specifically left as open:
But then again, coming from a source that thinks mid-level GPUs like Pitcairn are over-engineered with 192GB/s of bandwidth
And I must chuckle also that if Orbis has 8 CPU cores that is 2x what most of you were ranting about just months ago.
I have not seen any humble pie eaten over getting the CPU count wrong by such a *huge* margin. That would be like ignoring saying "Orbis has 18 CUs" and then it comes out with 36CUs! But I have not seen any blinking about the integrity of rumors or leaks.
Sorry, it must be nice to have MS leakers giving you information but the Durango Defense Force is already out in full strength. It is probably time to have the leaks vetted before they are posted before we end up circa 2005 all over again.
