I called Nvidia and AMD headquarters and told them to stop wasting their time and go back to manufacturing their graphics cards with DDR3 memory , all I got was an awkward.. huh? than followed by silence from their engineers..

I don't feel educated enough in this stuff to shoot any argument down about the speed of memory and bandwidth (you bloody geeks ;) *BUT* a few things that don't sit right with me.... I don't think i have actually seen *any* developer say that the Xbox is a powerful machine... the only comments ive seen is that the Cloud is something that could be useful (and we know all about that). The bit thats bolded (that i didnt bold but you did)... is false with *ANY* tech that starts to get used more (and GDDR5 if being used more and more now)... the cheaper it gets... so it wont stay costly. That makes me discount that argument straight away.. because if they cannot get that right, then the rest of their argument is surely up for mis-information. Finally.... we only have spec's for the PS4... Xbox have not released any specs except for 5 billion transistors. There are only two reasons for not releasing specs: 1. They are changing the specs (very very unlikely) 2. The machine isnt as powerful. That is all :) |
Sigh...
I'm not saying Xbox 1 is more powerful. It most likely isn't. I'm just saying that its built to be utilized to the best potential with the hardware included. Everyone dings it for not having GDDR5 RAM, and I am saying it isn't necessary to maximize its performance.
I find it hillarious that people here they think they know better than Microsoft and AMD R&D teams and that the design decisions Microsoft made, made the console less powerful, more constly to make, produce more heat and consume more power, and probably break the moment you turn it on.
Only on VGchartz...

I don't think people understand what the point of your post is though.

? I don't really understand what that actually means. They made it the best they could? Yes perhaps they did, but what does that actually mean... they tried their best?
Not trying to be a dick here, .. the Original post is a bit random.
Making an indie game : Dead of Day!
Keep believing that any "GAMING" system whether is a pc, consoles, tablet or any device that demands GPU performance rather than more CPU that is being built or program around DDR3 type memory and expect it would perform equal or better than one built around GDDR5 memory.. you just kidding yourself. for gaming, strictly gaming and gaming only GDDR5 is the best choice any hardware manufacture can offer. and to sweet the deal is to have a faster graphics card along with it.
Sorry to burst your bubble.

Hey at least he isn't wasting his time defending something that is blatently and obviously incorrect so that he can keep pretending that a thought he had was original and genious instead of accepting the fact that he was just thinking about things he in no way understands.
You wouldn't believe some of the posts people make here man! ;)
Prediction for console Lifetime sales:
Wii:100-120 million, PS3:80-110 million, 360:70-100 million
[Prediction Made 11/5/2009]
3DS: 65m, PSV: 22m, Wii U: 18-22m, PS4: 80-120m, X1: 35-55m
I gauruntee the PS5 comes out after only 5-6 years after the launch of the PS4.

disolitude said: Your whole post falls appart when you add memory bus bandwidth. 7770/7790 has 128 bit bus...X1 has 256. This + SRAM embed is why Xbox 1 GPU will beat both AMD GPUs in performance despite using DDR3 memory. |
The size of the buss didn't change the performance of a GPU... the bandwidth change.
HD 7770 uses a 128bits @ GDDR5 so only 72GB/s bandwidth... Xbone has a 256bits @ DDR3 so only 68GB/s bandwidth... the Xbone GPU in this scenario (not adding the console optmizations or eSRAM) will have a comparable performace if they run at the same clock but Xbone GPU runs at 200Mhz less clock but have more 2 CUs.
But we are talking ot about CUs or core speed here.
In terms of bandwidth it is really low for a GPU of 7770 power... in fact HD 7770 was a disapointed when launched due the 128bits bus... the 256bits with GDDR5 should be a killing GPU.
72GB/s bandwidth make the HD 7770 be weaker than GPU launched two year before with more bandwidth like:
Just for reference the specs of the GPUs listed.
HD 5870: GDDR5@256bits 153GB/s
GTX 560: GDDR5@256bits 128GB/s
Of course... the HD 5870 have better specs but the GTX 560 not... there are the GTX 570 and GTX 580 over the GTX 560.

disolitude said: Here you go buddy... This thread sumarized by 1 sentance. http://www.anandtech.com/show/6972/xbox-one-hardware-compared-to-playstation-4/3 "Even if Microsoft can’t deliver the same effective memory bandwidth as Sony, it also has fewer GPU execution resources - it’s entirely possible that the Xbox One’s memory bandwidth demands will be inherently lower to begin with." |
I agree... the Xbone GPU require less bandwidth than PS4 GPU because the PS4 GPU is 50% better.
But you missed something important... the PS4 memory bandwidth is 200% better... you know 68GB/s is way low for what Xbone GPU delivery.
The Xbone GPU needs at least 125Gb/s to match the bandwidth of PS4 related to GPU power.

I was trying to cheer things up as things are not making any since anymore and things were getting bitter.. LOL .. Thx man..

All this is fine and correct when it comes to PC GPUs but not how things are set up to work on Xbox One.
The Xbox One will have 68GB/sec of bandwidth between the CPU/GPU and RAM. Also the GPU will have 102GB/s of bandwidth to a local 32MB SRAM cache, and another 30GB/s of bandwidth to gamepads, Kinect, and other peripherals.
Even PS4 isn't as simple since on the PS4 side, you have 176 GB/s between CPU/GPU and everythign else. 7850/7870 have around 150 GB/s if I remember correctly, but that is only for the GPU. PS4 has to share that bandwidth between everything.
Here is an example of how Xbox 1 will work at maximum load (1080p@60 fps) - http://www.vgleaks.com/durango-memory-system-example/
There is way more shit going on here that... RAM speed + Bandwidth + GPU cores
