Re: Xbox One

While they have the same base APU(AMD Jaguar), the APUs are modified in a different way for each console. MS went with eSRAM(on board memory), while PS4 kept the more compute units(I think it's like 18 to 12 in favor of PS4). that gives the PS4 more potential in terms of performance. It still all comes down to developer implementation though.

your right, it will come down to developers, still imo, I think both will fair just fine.



Hope to own both by spring, but the One is my first choice.

Re: Xbox One

The explanation I tend to get is always the same tired one that explains nothing. "GDDR5 is 10x faster than DDR3". That's all they say.

Which is a terribly, oversimplified answer. They both have their uses, nor is one "inherently better" than the other.

GDDR5 is based off the DDR3 SDRAM. It is a high-latency, high bandwidth RAM that is capable of read/write on the same cycle where as DDR3 can only either read or write on a given cycle.

The easy answer is in terms of pure gaming application, GDDR5 outpaces DDR 3 heavily. The easy answer in terms of system performance (say for... a PC or XBone which emphasizes multitasking and random push/pulls) is that DDR3 is much better for those applications due to the way everything works.

For gaming performance, though, GDDR5 has no equal. There's a reason all graphics cards use it as their choice. Granted, these are specifics for AMDs graphics cards, but the point still stands.

512MB GDDR5 v. 1GB DDR3

1GB GDDR5 v. 2GB DDR3

Also, the 10 times number is pretty incorrect if people say it's "10x" faster. That number is closer to 3x. The PS4 will have around 176.0 GB/s for it's system memory bandwidth. The XBone's DDR3 will provide about 68.3 GB/s for it's system memory bandwidth. The eSRAM the XBone uses will have a bandwidth of ... who knows. It's 32 MB. Somewhere between 102 GB/s to 192 GB/s. I've seen varying numbers everywhere.

Re: Xbox One

This is what I dont get, both systems are basically identical, accept for Sony going with DDR5 opposed to MS DDR3, thats it. So can someone explain to me how based on different memory how that makes the PS4 surpierer?? Cause working in the technical field the last 14 years, the difference between DDR5 and 3 is not going to make a system that much more powerful.

Let's toss some numbers around.

PS4 has 176 gig/sec of RAM bandwidth. Xbox One has 68, not counting the eSRAM. Now, this is unified memory, so it can't all be used for graphics. The CPU is going to want a bite. Let's say it wants 15 gigs/second. That's a reasonable guess, but it will vary from game to game. So, taking away 15, we're looking GPU bandwidth of 161 on PS4 and 53 on XBone. The PS4 is 3 times faster. The simple design of it also makes it very efficient. That's what the eSRAM has to compete with.

The eSRAM is also going to be limiting for games targeting 1080p, since there's only 32MB to fit the render targets and framebuffers. Killzone Shadow Fall used something ridiculous like 500MB of render targets at the February press conference, and using triple buffering to remove screen tearing requires three frame buffers rather than two, so they might not be able to do that without dropping the resolution.

This is with just the difference in RAM between the two systems, as the PS4 has a big advantage over the Xbox One with the GPU. The PS4's GPU is also set up to handle GPGPU better than the Xbox One's, and some developers have already said that GPGPU is the future in gaming, especially when the CPU of both consoles is kind of underwhelming.

Xbox One GPU
1.18 TFLOPS (available for games)
12 Compute Units (768 ALUs/Shaders)
48 Texture units -> 40.9 GTexels/s
16 ROPS -> 13.6 GPixels/s
2 ACE, 16 queues

PS4 GPU
1.84 TFLOPS
18 CUs (1152 ALUs/Shaders)
72 TMUs -> 57.6 GTexels/s (Texture Fill Rates)
32 ROPS -> 25.6 GPixels/s (Pixel Fill Rate)
8 ACE, 64 queues

The PS4's GPU has a pixel fill rate of 25.600 GPixels/s. If Microsoft wanted to match that with their 16 ROPs, they would need to increase clock speed of the Xbox One's GPU to about 1500-1600Mhz (it's currently at 853mHz). To match PS4's texture fill rate of 57.600 GTexels/s and theoretical FLOPS power of 1.84 TFLOPS, they would need a clock speed of around ~1200Mhz. And this is without taking PS4's bandwidth advantage into account.

Edit: The presence of eSRAM also makes the Xbox One more difficult to develop for than the PS4.

Re: Xbox One

I knew trap would be in here in a heartbeat to put up those numbers lol.

Go ahead and throw out the cpu numbers as well while you're at it. You kinda just dismissed them saying they're underwhelming. You also mentioned the future being gpgpu.

I honestly don't know the cpu numbers on the two consoles.

Re: Xbox One

Most likely we will only notices difference in graphics for exclusives right ? Not third party's ?

I mean even if COD is 720p Xbone compared to 1080p ps4 will it look that different?

They both have essentially the same CPU, but the Xbox One's is upclocked to 1.75Ghz, while the PS4's is (I'm guessing here, because it was never officially stated) only at 1.6Ghz. I believe that both systems reserve 2 of their 8 CPU cores for the OS, so this would mean that the Xbox One's CPU is around ~6-7 GFLOPS more powerful.

Edit: The reason that they're underwhelming is because they are comparable to low end laptop CPUs. The Cell was theoretically more powerful (~230 GFLOPS) than the Jaguar CPU (~100 GFLOPS) and the Jaguar isn't much of an upgrade over the 360's Xenon CPU (~78 GFLOPS).

Completely depends on the person. I see some say 720p isn't a big deal to them, but I know to me it's a huge deal and I can easily tell the difference between the two.

Put it this way. 720p puts 921,600 pixels on the screen. 1080p puts 2,073,600 pixels on the screen. More than double. If you can't see why that's a huge plus in gaming and graphics quality, I don't really know how to explain it.

Re: Xbox One

Its times like this that I wish I understood all the lingo and what not.... but I don't.

I think Microsoft just needs to sell it for 350. Seems crazy to sell it more than the ps4. Just from a common sense perspective after looking at all the numbers as a whole.

But I understand why they are rolling the dice. Their brand is strong in North America, most people don't care about the specs. At least parents don't. They just know Xbox. Who knows though. Like someone else said in this thread anything can happen during a launch window.

Edit: Nevermind I forgot that it comes with kinect. That is why it is more expensive. My bad.

They have owned North America and, though I don't know the effective cost, bundling the Kinect in with it (which they seem to really want to push for some reason) and selling for 350 seems like it'd be quite a steep loss to take.

I don't see them dropping far behind the PS4 in NA. They won't match last gens sales numbers, I don't think, but I can still see the two consoles being close in North America. XBone will get blown away overseas though.

I can see the Xbox One possibly winning in North America at launch. Like previously stated, in NA when people think of gaming, they see Xbox. I don't see them blowing the PS4 out of the water, but I do see it being very close.

Now, I think it's fair to say that the Xbox doesn't stand a fair chance in beating the PS4 overseas.

I'm excited for both. I don't know if we'll ever see this big of a launch, when two big consoles release in a matter of one week.

According to polls and preorders the PS4 has much more of a chance of outselling xbox One at launch, even here in the U.S. I think, not the other way around.

I read an article last week that the PS4 had 725,000 orders here I the U.S. Versus Xbones 525,000.

Re: Xbox One

Inevitably will be photoshopped into "This is a pre-rendered commercial, not a game"

Edit: misread and thought it said 'this is innovation'

Love that commercial though.

Re: Xbox One

People are making waaaayy too big of a deal out of the hardware differences. I know it's part of the console wars and all, but anyone who is using the small differences in hardware to justify their decision (unless you literally could not care less about 1st part games) is way off, IMO.

http://www.thesixthaxis.com/2013/10/...ost-identical/

“We only need one console. Why do I have to make two versions of a game? And when Xbox One was first announced it had lower specs than PS4, but now they’re almost identical.

“So either will do.”
