$399.

I really don't have a good guess. It's coming out in a year and a half, so I can see it being anywhere from 500-650.

Not a penny over $399.

It's likely just a custom Polaris 10, which is a $200 *retail* GPU this summer. To be honest if MS wanted to push it they probably could sell it for $350 even. 18 months is a long time for the GPU tech to mature and drop further in price.

The GPU is worth around $200 alone (in production cost) and you need to add an X1, so $599 is realistic, not less than $499 by the end of next year.

lol, not a chance in hell MS is paying anything close to that. They are not some rinky dink little kid buying one GPU at a time from Best Buy, they order for multiple years in a volume of millions, they will get a price probably half that, if not less. The GPU itself will be cheaper in 18 months anyway. 

The PS4/XB1 equivalent (roughly) GPUs were the 7850-7870 AMD, and they were about $300 when they launched in summer 2012 (pretty much the exact same time line the Polaris 10 is on relative to the Scorpio launch). 

So the PS4/XB1 GPUs were actually more expensive for their time. Polaris 10 is a nice piece of kit which is dirt cheap, MS is smart to jump on it. 

By controller I meant, the actual game controller, as it seems odd to sell something like Scorpio without the Elite controller.



Also Tflops is an objective measurement between architectures.  It is literally a measure of computing performance counting the amount of instructions it can perform per second. I will conceed to your other points but that one is just plain incorrect.

Rendering a game is more than just the floating point math.

Let's use the Radeon 5870 as an example here, based on the Terascale 2 architecture, aka. VLIW5 (Very Long Instruction Word-5 way.)
It had 2.720 Teraflops.

It's successor the Radeon 6950 is based on Terascale 3, Aka. VLIW4. (Very Long Instruction Word-4 Way.)
It had 2.253 Teraflops.
Now despite the fact that the Radeon 6950 was almost 450Gflop's slower than than the 5870, it pretty much outperformed it in every game.

But dont take my word for it.

Let's take the Radeon 7850 then shall we? Based on Graphics Core Next 1.0, which introduced a massive change compared to AMD's prior architectures.
It has 1.761 Teraflops.
Despite the fact that it has 950Gflop (That is almost an ENTIRE Teraflop!) It actually out-performs the Radeon 5870.

But don't take my word for it.

Again I reiterate, Gflops is not a denominator for gauging the complete performance of a graphics processor, you have bandwidth, compression, caching, scheduling, geometry, texturing and more to worry about.
You could have a 9000 Petaflop graphics processor that is slower than a 1 Terfalop Graphics processor if it's design is inefficient.

Even in heavy-floating point compute scenario's (Where the use of Gflop should have some kind of importance) the 7850 will STILL beat the 5870 every single time.

Now it gets even more ironic as this is all a comparison between AMD's hardware, the difference becomes even more pronounced when you throw nVidia into the mix.

So. I ask you this. Still think your Flops is an accurate denominator for gauging performance between different graphics processing architectures? Because it's not. Never has been, just like how "Mhz" isn't a way to determine the performance of a CPU.
