The ROP count isn't just a solid number, the clock-speed affects ROPs. So let's break this down.
32 at 911mhz = 218gb/s
32 at 1172 = Xgb/s
Theoretical maximum the ROP units can have in Memory bandwidth, it does not work that way, but since AnandTech assumes it does, we'll do it too. As there is overhead, and you'd never want to use your entire bandwidth just for the rasterizer output pipeline alone. The CPU also wants some of that juicy bandwith you know . But let's just say for the sake of Anandtech it does fill it up completely, and we do know that the ROPs are affected by clockspeed of the GPU.
the 32's we can stripe away as they are the same for either system. So we can just solve for X.
X = (1172/911)*218 = 280.456641 or 281gb/s
So if we keep the constants we come at a 281gb/s bandwidth for the Scorpio. Which is correct considering it is clocked about 28% faster.
Now if we subtract this value from the 326gb/s number.
326gb/s - 281gb/s = 45gb/s.
So the "crossbar" is 45gb/s and probably reserved for the CPU to access the memory without bothering the rasterizer operations pipeline. It can also probably be used by the GPU itself (As it goes through the GPU) for other tasks than graphical (for instance physics calculations. This actually is a smart design, as it would allow the CPU to access and manage it's memory via it's own dedicated controller/path while having plenty of bandwith for itself to keep it fed. 45gb/s is plenty even more than enough for a Jaguar. In fact AMD chips are notorious for performing better with higher clocked memory/more bandwith, unlike Intel where it matters less usually, on am AMD it can give you a nice boost. So if it is indeed a dedicated 45gb/s for the Jaguar + (as the power management stuff is something I really want to learn more about, it seems very interesting and novel and unlike the normal Jaguar/Puma chips), then we might have found the reason why it punches above it's weight.
So yes, by just going "OMG it's 218 just like the Pro", Anandtech doesn't do itself any favours and is actively spreading FUD. They of all people should know that ROP is more than just their number alone and that clock speed affects the ROP speed. That is assuming that MS put 32 ROPs on there (that isn't even certain yet). It could be more, and it could be less. I expect MS to cheap out on these things. , they've done that too much as of late. (One Drive and Windows phones are recent examples. ).
PS: With ROP's we are talking about fillrate, not bandwith . But since AnandTech chooses to go this route, I found it funny to stick with it. The ROP fillrate should align with the memory controller's bandwith. So you can't just say it has <x> bandiwth and since it is 32 in both they are teh same speed. No with a higher clockspeed the fillrate increases but with a higher clockspeed also the Memory controller's speed increases. It just isn't as simple as "32 = 32", there are a lot more factors to compare.
The power difference between these consoles is sort of a bad arguing point for the loyal here on union. It's similar to the ps4/xb1 scenario but amplified even more, so its like all the people arguing FOR the power difference then are now arguing against lmao.
Works both ways, the only difference is the disparity is more this time.
If it were that important, most Xbox gamers in this forum would have done most of their gaming on PS4. Even MS realizes this.
I'm a little bit jealous of the xbox loyal who have stuck with XB1 and are jumping to scorpio. They're literally going from near the bottom of the pack all the way to top by a huge margin.
Thinking about their plans with the 360 games being enhanced, you have one of the best generations of games being "Remastered" to 4K 60fps with better anti-aliasing and better texture rendering without having to rebuy them.
900p vs 1080p is bigger than 30% its over 40%GPU performance (higher frame rate and/or pixel count).
Examples:
A game which runs at 900p (X1) vs 1080p (PS4) with the same frame rate is getting about 30% more performance from the GPU.
A game which runs at 40FPS vs. 30 FPS in the same scenario is getting about 30% better perf from the GPU, if the perf gap is due to being GPU bound.
For context, kb said that my claim that CPU and GPU performance is on X1 is proportionately better than PS4's was unsubstantiated, but it's demonstrably not:
Raw CPU power is 10% better on X1.
The only game we know of which is CPU bound runs on average 15% better on X1 under CPU bound conditions.
Therefore, X1's CPU real-world performance (+15%) is BETTER than the raw hardware gap (+10%). This means the software runs better/more efficiently on X1.
This tells us that X1 gets better than 10% CPU performance in the only case we know that's measurably CPU bound in a shipped title.
Raw GPU power is 50% better on PS4.
Across the gamut of comparables, however, the general performance gap is only around 30%-35%.
Therefore, X1's GPU real-world performance (-30%) is BETTER than the raw hardware gap (-50%). This means the software runs better/more efficiently on X1 with regards to the GPU.
In the VAST majority of DF comparisons I've seen, PS4 regularly gets about 30%-35% better performance than Xbox 1. This tells me that, even though the PS4 has a superior GPU by 50% (it has roughly 50% better TF performance), PS4 games aren't seeing that full performance advantage over Xbox One. This tells me that Xbox One games get better performance per clock than PS4 titles, which would make sense, given the heavy investment in DX12.
Therefore, kb was wrong/incorrect. My statement was very well substantiated, if not demonstrably provable.
I win the common sense that 4.2 and 6TF's isn't enough to do 4K in every game.Just Val attempting to show he is correct and Scorpio's bump in performance over pro as negligible. If 100% of Scorpio titles aren't 4K he wins something in life.
You can get a adapter to use the XB Elite controller...This is me. Actually I wouldn't call myself a Xbox loyalist. More of the Xbox controller loyalist. Lol Since getting the Elite controller, I won't consider multiplats on anything else. My Pro is only for exclusives even now. So yeah...buying a nice HDR 4K tv and Scorpio in the fall should feel like a significant step. Can't wait to see Forza 7.
This would be pretty decent if true.Thinking about their plans with the 360 games being enhanced, you have one of the best generations of games being "Remastered" to 4K 60fps with better anti-aliasing and better texture rendering without having to rebuy them.

Its a losing argument Scorpio is more powerful across the board.The power difference between these consoles is sort of a bad arguing point for the loyal here on union. It's similar to the ps4/xb1 scenario but amplified even more, so its like all the people arguing FOR the power difference then are now arguing against lmao.

Not every one and some have fw updates to resolve this(no i don't remember which ones)Except the adapter has issues including frequent disconnects. I looked into this extensively.
I win the common sense that 4.2 and 6TF's isn't enough to do 4K in every game.
I said this when both were announced yeah me!
I think 1080p to 4K is more likely as the 900p games take more to run hence the lower resolution.Microsoft seems confident that 900p &1080p games can run natively at 4K on Scorpio. We'll see.
I would mind checkerboard if a dev chose to do that.
Not true the elite controller have an app to do a lot of settings for profile games.You can get a adapter to use the XB Elite controller...
win win
Some semi work aroundsNot true the elite controller have an app to do a lot of settings for profile games.
None on the on the ps4 plus how the rumble works which is still ahead of the duel shock controller is written for the xbox platform.
Wasting money to get nothi g when you spent that much money on a controller.
Some semi work arounds
Yup! Every game is automatically improved - system wide.Is this confirmed? I still have about 60 games for 360.
Sing it with me...I win the common sense that 4.2 and 6TF's isn't enough to do 4K in every game.
