VGleaks: World Exclusive Orbis Unveiled!

[QUOTE="CwlHeddwyn"]Question is: if these specs are accurate finalised specs for PS4 &720 then what route are MS going down? The power advantage for the PS4 will be significant and I imagine 720 will struggle to compete when it becomes obvious to the average gamer. MS did well with the X360 because it could compete with the PS3 graphically due to the excellent combination of CPU, RAM and powerful GPU. Despite all of Sony's claims of being 2x as powerful the X360 held its own because you could see visually speaking the truth. so if these orbis and Durango specs are true then X360 will struggle to compete graphically.and PS4 could well dominate especially as it will have better looking multiples and better looking exclusives. The extra power could well encourage more exclusives.tormentos

MS and Nintendo are going in 2 completely directions. Nintendo is just trying to make something for everyone with new ways to play games, gamers and family alike. MS are just making something for the gadget whores glued to their next big social media kick. MS have been trying to be apple for a while now.

PS4 is going to be the go to console for games, maybe even more than Wii U. I'm extremely excited for PS4. I'm just thinking that if it can win developers over MS's console because of power and toolset, it might be the big break Sony needed.

[QUOTE="Mystery_Writer"]@ronvalencia Based on the rumors so far, I think it's safe to call PS4 as the winner here in terms of graphics, right?tormentos

Don't forget you need to take Sony's over the top BS into the equation! So....

NextBox leaked specs = Somewhat accurate

PS4 leaked specs = (PS4 leaked specs / 2) = Somewhat accurate :lol:

These specs are much more accurate than the dev kit specs. 8 core CPU instead of the 4 dual cores, unified 4GB fast GDDR5 instead of the 8GB DDR3 and the 2.2GB videomemory. These specs are quite good, and if the difference between the two consoles will be as big as this, the PS4 will perform quite a bit better than the next xbox.

I still have one question though, which API access yields better & faster results for developers, LibGCM or HSA? or are they about the same?

i heard that jag cores are for low power devices like tablets. so does this mean ps4 is teh weak?

[QUOTE="TheXFiles88"]

[QUOTE="tormentos"] Actually i wasn't celebrating but if you most know the PS4 one still quite faster,the 720 on is 68GB/s + 102GB/s but that doesn't mean they should be accounted like 170GB/s,go search on Beyond or Neogaf you can't combine those numbers,is 68 from one point to another and 102 from one point to another.. Unlike the PS4 176GB/s one.tormentos

You know, the DDRx DRAM has already been outclassed by a new revolutionary DRAM which called "Hybrid Memory Cube" It is a multi-chip module which works in parallel with the multi-core processors. The advantages are enormous over the DDRx. It costs less, 15x more performance, consumes less power and takes less space than a typical DDR3. If Microsoft is going to use this new HMC in its new Xbox (I don't think why they shouldn't), it will be a game changer since Microsoft is currently 1 of the 10 members of the HMC consortium. Just wait for the final specs after E3...;)

"Hybrid Memory Cube is a revolutionary innovation in DRAM memory architecture that sets a new standard for memory performance, power consumption and cost."

- HMC Combines high-speed logic process technology with a stack of through-silicon-via (TSV) bonded memory die.

- HMC delivers dramatic improvements in performance, breaking through the memory wall and enabling dramatic performance and bandwidth improvements -a single HMC can provide more than 15x the performance of a DDR3 module.

- The revolutionary architecture of HMC is exponentially more efficient than current memory, utilizing 70% less energy per bit than DDR3 DRAM technologies..

- Hybrid Memory Cube's increased density per bit and reduced form factor contribute to lower total cost of ownership, by allowing more memory into each machine and using nearly 90% less space than today's RDIMMs.

- With performance levels that break through the memory wall, Hybrid Memory Cube represents the key to extending network system performance to push through the challenges of new 100G and 400G infrastructure growth. Eventually, HMC will drive exascale CPU system performance growth for next generation HPC systems.

- Whereas DDR4 represents an evolutionary standard, HMC is a revolutionary technology that is a complete paradigm shift from current memory architectures.

- Hybrid Memory Cube will redefine memory. By advancing past the traditional DRAM system, HMC is setting a new standard of memory that can keep up with the advancements of CPUs and GPUs.

- Hybrid Memory Cube could be an absolute game changer for applications ranging from high performance computing to consumer technologies like tablets and graphics cards that value a combination of form factor, energy and bandwidth.

"Micron Readies Hybrid Memory Cube for Debut"

Hybrid Memory Cube (HMC) technology, a multi-chip module (MCM) that aims to address one of the biggest challenges in high performance computing: scaling the memory wall.

Memory architectures haven't kept pace with the bandwidth requirements of multicore processors. As microprocessor speeds out-accelerated DRAM memory speeds, a bottleneck developed that is referred to as the memory wall. Stacked memory applications, however, enable higher memory bandwidth.

The Hybrid Memory Cube (HMC) is a new memory architecture that combines a high-speed logic layer with a stack of through-silicon-via (TSV) bonded memory die that enables impressive advantages over current technology. According to company figures, a single HMC offers a 15x performance increase and uses 70 percent less energy per bit when compared to DDR3 memory, and takes up 90 percent less space than today's RDIMMs. The Cube is also scalable per application, which is not possible with DDR3 and DDR4. System designers have the option of employing the HMC as near memory for best performance or in a scalable module form factor, as far memory, for optimum power efficiency. This is a huge leap forward from a technology perspective, noted Graham, compared to DDRx and other boutique memory products that are out there.

Lol, just no.First of all the existence of the EDRAM is to help the GPU for "Free Antialiasing". Secondly for god sake, why would the design team decide to use DDR3 to begin with when there is this HMC which outperforms and costs than either the DDR3 or DDR4? I think you have to re-read what HMC is designed for:"...keeppace with the bandwidth requirements of multicore processors. As microprocessor speeds out-accelerated DRAM memory speeds, a bottleneck developed that is referred to as the memory wall".For example:

- 8G DDR3 can only achieve 68G/s (bandwidth)

- 8G HMC could achieve 480G/s(bandwidth)

The HMC will greatly improve the bandwidth which is needed for the modern multicore processors just as what is it intended to achieve.

So, the design team decided to spend $$$ for the DDR3 in order to cause bandwidth problems to begin with and then turned around the corner and saw the problems coming and decided to spend additional more $$$ just to add EDRAM? Does it really make sense to you at all? As I have mentioned before, the existence of the EDRAM is to help the GPU for its final data processing for "FREE ANTIALIASING". So you think the EDRAM in the current Xbox was designed to help the 512MB GDDR3 or was it "INTENDED" to add "FREE ANTIALIASING"?

This is the reason why some people have claim they are close. Orbis has 2 more CU than Durango,but also has 4 more CU for physics and many other stuff. ""This issue has been explained in this thread over and over and over again. This is a customization to make Orbis a monster in terms of compute. If you give any F*** about destructability, physics, animation blending/culling, lighting, or anti aliasing, you will want this to be as customized as possible. Those 4 CU's you just wrote off, are THE secret sauce. Go read it. Traditionally certain features / effects can cripple a GPU. Just look at how PhysX affects AMD cards. However, instead of letting that happen, Orbis has dedicated 4 CU's to make those certain features relatively painless and not as much of a burden. This is GPGPU or HSA."" In other words, this is a GOOD thing."" http://www.neogaf.com/forum/showpost.php?p=47029526&postcount=2392 This is not something that paint good for Durango,while it seems Orbis is just marginally more powerful because it has 2 more CU,is actually allot more,when you take any physic and other effects and ad them top the equation which will handle by the extra 4CU... What this means.? Frames,AA,physics and several other will tent to favor Orbis specially if the game is physics intense,with many explosions and stuff like that,on 720 the physics could be run on the CPU to avoid hit performance,but you are eating CPU resources those the PS4 will be use for other purposes. tormentos

On "Just look at how PhysX affects AMD cards" statement, PhysX is a proprietary realtime physics engine middleware SDK from NVIDIA.

Refer to AMD's Bullet/OpenCL physics demos.

Not too sure what you mean. Isn't the high bandwidth of EDRAM on X360 the reason for the "free antialiasing"?

And if that's the case, why would they need slower ESRAM for X720 if they're planning to have HMC (which would give them the 'free' antialiasing without the cost for ESRAM)?

Also, is HMC ready?

Since the GPU's usually bombared with lots of information, thay do need help for final data processing from the EDRAM such as the case in the Xbox 360. also pay attention to this quote: "The eDRAM holds the contents of all of the back buffers, does the resolve, and hands off the resulting image into main system memory for scan-out to the display."

"The GPU won't be using system memory itself quite as much as one might expect, because it packs 10MB of embedded DRAM right on the package....The really fascinating thing here is the design of that daughter die. Feldstein called it a continuation of the traditional graphics pipeline into memory. Basically, there's a 10MB pool of embedded DRAM, designed by NEC, in the center of the die. Around the outside is a ring of logic designed by ATI. This logic is made up of 192 component processors capable of doing the basic math necessary for multisampled antialiasing. If I have it right, the component processors should be able to process 32 pixels at once by operating on six components per pixel: red, green, blue, alpha, stencil, and depth. This logic can do the resolve pass for multisample antialiasing right there on the eDRAM die, giving the Xbox 360 the ability to do 4X antialiasing on a high-definition (1280x768) image essentially for "free"i.e., with no appreciable performance penalty. The eDRAM holds the contents of all of the back buffers, does the resolve, and hands off the resulting image into main system memory for scan-out to the display."

I don't believe the 4GB RAM part. Why would Sony send dev kits with 16GB RAM if that were true? Dev kits have always been known to have twice the memory as the console. So the PS4 would have 8GB. I truly doubt we'll know the real specs until Sony announces it. These rumors keep changing what the specs are.

eDRAM is for far more than antialiasing. A lot of games don't even use hardware AA on 360. It's for everything that requires blazing speeds, including the framebuffer. MS liked to throw around the free antialiasing shtick as an example of what you could do with it only. Even funnier they said it could handle 4xMSAA by itself, typical spreadsheet BS. Gamecube and Ps2 both have eDRAM as well, yet almost no games to my knowledge use AA.

You don't understand that even if this new RAM is infinitely better, the fact that it's new technology would cost MS more money. I've never even heard of this new ram, it's a good thing ram is finally evolving again if it's all true, but the fact remains it's brand new technology and you can't just slap that in a device all willy nilly. I'm sure these consoles are very close to being finalized.

if MS is planning to use free antialising on every title, I'll have no problem avoiding it.

Because Free Antialiasing looks like dog crap, It more often than not blurs the image and reduces overall quality.

Xbox 360's "free MSAA" only works with certain workloads and it's not optimal with deferred renderers (for cheap plenty of lights effects).

AMD's "Forward Plus" render re-enables MSAA hardware usage but with deferred render level "plenty of lights" effects.

AMD has a similar architecture which called "Interposer Stacking" in their new graphics cards and suppose to be in the next Xbox's "Oban" chip since the funding comes from Microsoft for the development of the chip and they are also a memeber of the HMC consortium.

Yeah, I agree. Even if this HMC memory is cheaper to make, it's still new tech, and it won't be cheaper for MS to use. DDR3 is mass produced and the cheapest RAM, especially if they are going for a 8GB setup. Also, they would have to get AMD to develop they're components to utilize the HMC memory aswell, and that would not be cheap, or easy.Martin_G_N

As microprocessor speeds out-accelerated DRAM memory speeds, a bottleneck developed that is referred to as the memory wall".For example:

- 8G DDR3 can only achieve 68G/s (bandwidth)

- 8G HMC could achieve 480G/s(bandwidth)

The HMC will greatly improve the bandwidth which is needed for the modern multicore processors just as what is it intended to achieve.

On Smart eDRAM's MSAA, ATI didn't factor in certain workloads which resulted in less than optimal setup.

AMD attempted to address this issue with AMD "Forward Plus" render i.e. moving the main problem from memory to compute.

Compute improvements are currently outpacing memory improvements.
