| HollyGamer said: Remember PS5 has small compute unit than Xbox SX so the bandwidth on RAM is enough also for that, Xbox SX also has split memory for the speed , 10 GB @ 560 GB/s, 6GB @ 336 GB/s |
The number of compute units is a non issue.
If you have 16 Compute units @2ghz, then in theory they would perform the exact same as 32 Compute units @ 1ghz. It's a function of clockrate x compute units... And because of that, their bandwidth requirements would be identical.
The thing with the Playstation 5 is that in general it has about 20% less GPU capability on many fronts in an ideal perfect situation, it may even be greater than that depending on how the Playstation 5 manages clockrates when the entire system is loaded down.
The Xbox Series X doesn't actually have split memory, it's a single memory pool, it's just that a large part of that pool runs at a slower rate, so developers will need to ensure that certain parts of a game operate in the faster memory and other parts operate in the slower memory depending on how bandwidth intensive those individual tasks are... Microsoft is also using a chunk of that slower memory for the OS/background tasks, so the impact of that slower memory pool should be lessened for gaming.
Either way, without a doubt the Xbox Series X does have the bandwidth advantage... But this goes back to my point that there is more to both sides of the Playstation 5 and Xbox Series X story than the raw specification sheet numbers might imply.
| HollyGamer said: also it doesn't mean that if Xbox has more CU , PS5 cannot do simple lightning effect, the CU already powerful enough to do CG rendering for both, the problem is the more power the GPU is the more data you need. Especially if you want to make a realistic assets and high texture assets |
Not really.
The Xbox Series X should be able to include higher quality implementations of global illumination than the Playstation 5, whilst the Playstation 5 has higher quality texturing.
So whilst the Playstation 5's GPU is formidable (Remember MPixel fillrate on the PS5's GPU is better than the Xbox Series X's GPU and probably Geometry as well), the Xbox Series X does hold the overall edge.
How much is it going to matter? Like I keep saying, we need to wait on the games and see what developers do with each piece of hardware.
| HollyGamer said: Xbox will do great, it's just depend on the game engine game developer are optimizing for. |
It also depends on the type of game, for example big open world games that rely on lots of objects and geometry, will probably run best on Playstation 5.
Games that do allot of heavy scripting, physics, impressive lighting like a corridoor horror shooter... Will probably be best on Xbox Series X hardware.
Provided developers optimize for the various hardware nuances, there is never any guarantees for that.
| HollyGamer said: I never said there is no impressive games on Switch, but most third party games on switch are ported games from PS3 and PS4, so their games engine are a still a copied method from mechanical data structures, so no real time data path for assets. |
I was using it as an example that not all Switch games are built with mechanical drives in mind, in-fact I would say that any Nintendo exclusive probably doesn't as Nintendo has not ever had a mechanical hard drive in a mainstream console release before.
You had the Nintendo 64DD... But that was more a peripheral.
