Good point, I should have been clear that the XSX is not a true "split memory" configuration. I only mean the speed difference between the 10GB and the additional 6. You're absolutely right that shared memory isn't magic either. I was just addressing mostly why the memory configuration is ONE thing that people are speculating on that might be causing the XSX to lag behind or at least not show that numerical superiority over the PS5. Thanks!
You also bring up another thing that supports the point I was making. The original post I replied to was implying that because MS has so much money they MUST have designed superior hardware and wouldn't be held back by making compromises just to hit a certain price point. I was pointing out that Sony in fact had much more experience in designing and selling electronic hardware. But you bring up another reason it's silly to go with pseudo logic like this. Because you're right about the API's used by each system not being the same. Despite Microsoft being the "Software company" Sony his historically done better with their own software API's for their products.
You know, it's almost like the smaller company with more experience, does a better job of designing hardware and pairing it with effective software! How can that be? They don't have as much money!
I try to put the effort of my past experience to provide valuable input, I vastly prefer Microsoft way due to various reasons, however being at the development team, provided me with some additional knowledge, which I like to put, when I am not trolling. I enjoy banter, however I do not enjoy, when people claim that they have knowledge about something which they read on the internet or heard from grifters like Moore law is dead.
I also believe that the GDK has long way to go, when people are saying that tools will improve over time with both manufactures, I tend to not agree, you cannot get closer to HW than what Sony is doing, they can put effort with talented team, like ICE in PS3 era to developm some efficient algorythm to help devs, however I you someone wants to draw pixels directly from debug console, only options is PS5. You cannot do that on Xbox tricks like this, you have to go through layers of Direct X APIs (they are tailored to console, it's not like on PC....but maybe it was, I haven't looked on GDK yet), however I know for a fact that espeically with X1X coming, the SDK/Tools etc was mess in the background, it did things which was not suppose to. There is a whole layers which you cannot influence, if you try MS will reject it.
Also another fact is that with Hypervisor the whole game is bundle with Title OS (small kernel with approved APIs which you can use to talk to HW) and that system OS is in another buble, they are communicating basically like webpage with server. And that Title OS had long way to go and now I have no reason to believe it, that they are even close to being done. Skip-alpha of new OS kernle is full of bugs, games are shutting down consoles, which works on Alpha > builds. So as much as "tools" are good meme for laughs, I stand with what I said and I belive that XSX has it's strength, few days ago in this thread there was some info about MS finally allowing draw calls to be managed just by GPU and that's a HUGE news. However in MS fashion, there could be additional complexities, which going to take years to get advantage of. Specially big engines are developed slowly, they don't react fast to new features in SDK/GDK/TOOLS.
I think VRS, SFS and so on are great things to have, I also am not sure if Sony is having same-ish things in their toolkit. For me is confusing to hear that Geometry engine will fill the void on PS5 for these functions, I don't see connection. HOWEVER, it would be foolish to expect that Sony didn't do anything on the efficiency front.
Also it's fact that Sony is doing their own drivers for the APU, AMD providing just a bpart of bios, with MS they have driver from AMD, they are treating more like a PC, so there is a posibilities for huge gains.
Definitive and verifiable advantage which Sony have right now is ability to compress games (better put, to do this with HW logic, not SW) with Kraken and OODLE, it's probably temporary win, because BCPack is still in development, so we could possibly see some improvement, but I don't expect MS to catch with Sony, because one think for sure, MS is not that open using open-source software in their close environment.
There is tons of valuable talk to have, however if someone is throwing PR stuff around and don't even understand how is that suppose to work, it's a
tough job.
Hope someone appreciate my input.
