Does this help with working out GDDR5 costs?

4350 doesnt have gddr5. Look at a 6850 or something with gddr5 at a reasonable speed.

Granted that chart shows old prices, but surely the price wouldn't have dropped by 50%, would it? And also the double density would raise cost too.

The AMD 6970 has 176 Gb/s memory bandwidth using 1375MHz Memory Clock (5.5 Gbps GDDR5)
4 * $48.57 (2GB 6970) = $194.28

8 * $18.45 (1GB 6670/6850/6870) = $147.60
4 * $36.90 (2GB 6950) = $147.60

The AMD 6950 has 160 Gb/s 1250MHz Memory Clock (5.0 Gbps GDDR5)
The AMD 6870 has 134.4 Gb/s 1050MHz Memory Clock (GDDR5)
The AMD 6850 has 128 Gb/s 1000 MHz Memory Clock (GDDR5)
 
I guess my only question is, how feasible will it really be for developers to really use all that memory? I mean.. That's a ton of RAM.

Will the CPU and GPU even be capable of using that much effectively? Novice question I'm sure, but it just seems like developers have so much room to spread their legs out..

According to that chart, 8GB of GDDR5 would cost them like $70.

4.35 (512MB) x 16 (8GB) = $69.60

Uhh no. According to the chart, the same speed of GDDR5 is almost $50 for 2GB. $48.57 to be exact. So 8GB would be almost $200, $194.28 to be exact. Of course, that list is a year and a half old I think, so maybe its come down, but I'd still guess $150 or so.

Edit: Bah, one upped by BRit. ;)
 
Instead, the cost as of that sheet (which is probably well over a year old) is $147.62 for 8GB of GDDR5.

Sony will probably get a better deal, they are going to buy that stuff for at least 60-80 million units.

Although I wouldn't be surprised if this gen would turn out to be like, 100-100-40 million between Sony/MS/Nintendo...
 
You also need to take into account they will need double the density so that will make for more expensive ram parts as well.
 
搭載されている18個のコンピュートユニットは全体で1.84テラフロップスの演算能
力を有し、その性能をグラフィック機能やコンピューティング機能、またはその二つに自由に割り当てることが可能です。

Translate: 18 CUs free to dedicate to graphics or compute efforts as devs like.

14+4 seems to be out the window.

In the paper it also says that live streaming is not limited to Ustream.
Expected, twitch and ustream and other stuff all take FMLE/Xsplit/OBS so I wouldn't be surprised.

It would be absolutely ingenious if Sony put out the fake specs to make MS think they were only going with 4GBs of RAM and 14CUs + a separate 4 CUs (with limited graphics ability). only to change at the last minute when there was nothing MS could do.

Would Sony even include the concept of 14+4 in a press release or in this presentation though? It could still be 14+4 and doesn't make anything they've said today a lie.
 
I'm guessing the only reason they didn't announce the price is kaz didn't want a bruised ego again from becoming an internet meme, aka "$599 US Dollars." :p

I got that chart from this recent Anandtech thread, don't know how old the chart is though:

The official documents say that theres all 18CU's available for rendering or compute, kinda kills 14+4 imo.
 
I doubt it, those prices are bulk already from card production companies that buy in the millions.

Well, it certainly is a complex issue.

If they were playing catch-up to MS, and the 3GB reserved for the Xbox OS is true, then Sony could've gone with about 6GB and still get even or maybe ahead a little.

They wouldn't need the advantage of 2GBs more memory if they already have a faster GPU and more bandwidth, as it would just inflate their costs without any benefit noticeable for the majority of the market.

The most likely reason for 8 gigs is that it was easier and more cost effective to do hw wise compared to 6GB.

So it only makes sense to have that amount of memory if they were able to get a relatively good deal on it. If it would really cost them $200 then it'd be financial suicide.
 
Actually the quantities that Sony (or Microsoft for that matter) would order for consoles really don't amount to a hill of beans to most foundries. Heard an interesting stat from Paul Thurrott last week. Xbox 360 has LIFETIME console sales of some 76 million in the last 7+ years. The PC market, in the last 3 months, widely considered the worst PC quarter in over a decade; moved 90 million PC's. That's 3 months. And the tablet + smartphone market dwarfs even that. So as much as we love our consoles, relatively speaking, it's a small market. And I'm both impressed and concerned that Sony is investing so heavily trying to win back marketshare of such a constrained ecosystem.

Because for all that was shown, it's still clearly a gaming system, and not "designed" to expand the market in any significant way. And IF, other platforms, whether that be a competing console, tablets, smartphones, or some other new device, continues to erode at the existing base; they are going to be in a lot of financial trouble. And as much as I like Sony, and would like to see them succeed. A situation like that could cause them to faulter on many of the promised made today, as has happened in the past with some of the ideas they initially promoted.

Thank you for the posts, really helpful, I'm not even sure I followed what you did, but great input!
 
Sure there might be 90 million PCs, but how much of them have a graphics card with GDDR5 memory?

Not to mention tablets or smart phones, they are using pretty basic parts because of the very limited battery capacity, form factor, and retail prices.

I doubt that GDDR5 equipped video cards could sell more than, say, 5-10 million units at this time. An order from a console vendor with 60-100 million units will stand out, no doubt about that.
 
Really liked the new Infamous, KZ demo felt 'not ready' with placeholder animations and sounds, really wish Evolution had stayed with arcade racing and MMolecule ruled as usual ! Good show, but i missed the inital part where they showed the actual ps4 stuff.
