If the GDDR5 set up in the ps4 is so good then why...

[QUOTE="FPSfan1985"]Bullsh!t. Look at the hd 7850 vs the 7870. Like a 50% flop advantage, yet only a 10%ish difference real world. Even smaller in more demanding games. Even with 50% more terflops the 7870 only gets like 5 more frames in games like metro or crysis. A 30% advantage in terflops isn't going to be game changing at all.Truth_Hurts_U

Maybe you don't get that PC is not a console.

Software level vs HW level.

Stop trying you sound dumb.

I sound dumb yet you're the one making the claim that 30% more gpu terflops in going to be a HUGE advantage. pfft please.FPSfan1985

It will be... It's just that simple.

[QUOTE="legalize82"][QUOTE="FPSfan1985"] That 30% is a difference in teraflops. Real world differences will be negligible. FPSfan1985

Your math is way off it should be bigger than this ^^.

The xbox one is close to a 7770 in flops period which is GCN as well,the PS4 is over a 7850 again which is GCN.

We are talking about 1.23 vs .184 some 600 Gflops of difference that is more than 2 xbox 360 in power.

No it won't. I even explained why it won't. Please explain to me why you think it will.FPSfan1985

I already did... It's not that hard to grasp.

That is what you belive on reality is something way different.

The xbox one has 1.23 TF,from those 10% is locked away from developer and are use as system resources,which mean more like 1.1 TF for games if not less.

The xbox one doesn't have a second CPU for background task,2 core are also locked away for OS as well as 3GB of memory.

The xbox one has slower memory no matter what,you cant ad bandwidth like flops period.

[QUOTE="RyviusARC"]

[QUOTE="SKaREO"] Precisely this. The Personal Computer is more of a workstation than a gaming machine. It is not until you invest a large amount of money until you transform a PC into a gaming rig. Most PC gamers are not using gaming rigs. I'd say only about 3% at most have a computer that is capable of matching the PS4 in graphics processing capability.FPSfan1985

Lol my PC I built in 2011 is more powerful than the PS4 and it's a single GPU build.

Which is a 5-10% improvement in efficiency at best for the overhead on GPUs

That can be compared to a small overclock on a video card.

Overhead on CPU is a different story though.

[QUOTE="RyviusARC"]

[QUOTE="MK-Professor"]

The ps4 CPU is getting 20GB/s with high CAS latency. get over it.

for example my CPU is getting 48GB/s with low CAS latency, and my 2 GPU's of total of 600GB/s. LOL the 156GB/s ps4 GPU have.

MK-Professor

You do know that each of those GPUs have to share the same memory pool right?

we are talking about memory bandwidth not the amount of memory.

The reads are double the speed in sli/crossfire but the writes are the same as a single card.

Whether or not you consider the bandwidth doubled depends on how you look at it.
- For each frame, the bandwidth remains the same.
- For every two frames, the bandwidth is doubled. (AFR send two frames at the same period of time as a single GPU dose for one frame, assuming SLI/CF scale perfectly)

[QUOTE="Truth_Hurts_U"]

[QUOTE="legalize82"] and 30 % is not alot ?FPSfan1985

30% is alot and anyone that says other wise don't get that both GPU's are the same. One has less processing then the other. This isn't 360 vs PS3. These are all AMD parts.

There is no special cpu the other doesn't have... It also not AMD vs Nvidia like last gen.

You'll see the differance. Maybe not at first but 3 years from now your going to see 30% gap.

teraflops came from shader cores

1152sp * 2 * 800MHz =  1843200 (1.84 TFlops)

768sp * 2 * 800MHz =  1228800 (1.22 TFlops)

lol

Forget about that number! Instead focus on the numbers which are used to calculate those numbers!

Unified memory isn't easy to do at all and the PS4's memory setup would seem to go well beyond what the Xbox 360 did there.

AMD is working on bringing something similar to PC this fall with Kaveri, but don't underestimate the amount of R&D and testing that has to go into changing how memory is allocated and shared by programs: we're talking hundreds of millions to billions of dollars here.

Nvidia is going to be doing the same thing with Maxwell.

Not sure what you guys are talking but DDR4 is coming out next year on Haswell X99 chipset.

It causes latency/bandwidth issues from what I heard and it may hurt the cpu a little since cpu don't usually use that type of ram.Sony may have designed the PS4 to prevent this issue, but it still may be present.

This shouldn't be surprising, the performance gains are very considerable and they'd be foolish to not at least try to do the same.

It's not quite the same thing though, AMD is integrating the CPU and GPU as closely as possible while Nvidia is giving their GPUs an ARM CPU as a kind of co-processor. Nvidia really can't do what AMD (and inevitably Intel) will do there because they don't have a seat at the table when it comes to desktop CPUs and they aren't exactly setting the world on fire in tablets/smartphones either.

I'm sure they would be well off. If they don't see a good future ahead. They might as well bail out now rather then later. It's going to be interesting to see how Maxwell preforms or if there is any compatibility issues with older games.

Volta is gonna be nuts with 1TB a sec memory.

It's going to be awhile before CPU/GPU combos start to take a chunk of the dedicated GPU market.

My understanding is that Nvidia is losing money in mobile right now, but they don't have a choice in the matter if they don't want to be limited to providing a small number of high-end desktop/laptop GPUs and workstation/HPC graphics parts because AMD and Intel are both slowly but surely eroding the market for low-end discrete GPUs which is where a lot of Nvidia's shipment volume comes from.

I am looking forward to seeing what happens in mobile the performance improvements there have been pretty enormous and I see AMD making a push there as well in the future with their ARM license. Qualcomm/Samsung/ST-Ericcson aren't going to stand still either.

Xbox has sdram which bridges the bandwidth gap between ddr3 and gddr5 with better latency as well. But it;s not like memory isn't going to make an real difference anyway. And a 33% difference in teraflops mean almost nothing. Like comparing any two same family gpu models. FPSfan1985

No ony the 32MB of ESRAM have a 102gb/s bandwidth the complete 8GB of DDR3 only had 68gb/s and is share with the CPU as well.

There is no 102+68+20  like MS try to do it doesn't work that way.

The difference is as big as 50% and sites who know about hardware and PC had also state this,the difference is bigger on the PS4 vs xbox one than the 7770 vs the 7850,this is undenialble and is a fact.

Trying to imply that the difference is nothing,is like trying to claim that there is no difference from the 7950 to the 7970 or the 7870 to the 7850,there is difference and it will be show,and is bigger than 7770 vs 7850.
