[Tech-Radar]AMD on the PS4: We gave it the hardware Nvidia couldn't - Page 12

post #111 of 146
PS4 is ~15-16x more powerful than PS3, which is in line with what we got in the previous gen. Of course these days we have 300W GPUs that weren't standard back when previous console gen was released. The limiting factor of consoles is the cost and power consumption. They don't want to make a 500W heater unit that costs 1000$. You can only get so much power into a unit with 200W power limit and <500$ price tag. For that purpose the AMD APU is the best choice. It's cheap and power efficient. Sure Kepler is power efficient too, and Intel low voltage CPUs, but you can't put them on the same chip like the AMD APU and the total costs would be far higher. Nvidia doesn't do x86 CPUs and Intels HD Graphics is just laughably underpowered. It doesn't take a rocket scientist to figure out that AMD had the best perf/W/$ combo with their APU.

But there are laptops, tablets and smartphones with soldered DDR3. GDDR5 is a variation of DDR3, has been a very proven tech in GPU cards, and AMD can swap the DDR3 controller out for a GDDR5 controller used in their GPUs.

No compatibility issues, though the only restriction is that GDDR5 must be soldered to maintain signal integrity. But what console has replaceable system memory anyways?

How is that N64 can have memory upgrade explain me...

Also why are there no updated SKU's on consoles with a bit stronger hardware to improve frames per second and resolution in games... If this generation of consoles will last 7-8 years like current generation then in the mid way a SKU update that has higher clocked hardware...

Its possible if you have same hardware just slightly improved...

Modular code has a slight overhead, so to save some resources you go with a more static route. Look at embedded devices, the kernels/software for them is very set. You don't build a kernel for an android phone that supports other hardware, it adds overhead. Things like that really become noticeable on smaller devices, we traditionally treat consoles the same. That performance increase you get from using more linear code (static) might help you get the extra boost to do something as simple as FXAA.

I do think we could do some form of upgrades. Memory upgrades would be pretty simple, loading higher res textures with extended vram might be nice. These new consoles look to accommodate for the future, my home rig only has 8GB ram. I don't look to upgrade for a while, these consoles are using as much as I am. Faster too, so it looks very promising. The only thing I think is a downside would be the GPU they chose, I would have rather seen a more beefy solution. it'll get the job done, games will look pretty good and towards the end it'll shine like the Xbox. I just don't like the idea of waiting 5+ years to see the "true" potential of the hardware. Rather have them release a console with hardware that will go stale in 5 years, release a new console with similar specs and better hardware. I think a 6-8 yr lifespan is pretty excessive in the electronics world. But that won't happen, neither will I be buying a new console. =P

They sold a small cartridge called the expansion pack that you jammed into the console that would double the memory, but it was poorly thought out and only a few games took advantage of it.

You will NEVER see a console with new tech. NEVER. As a company - if that new tech fails, do you really want to deal with the repercussions? Of course not.

but they did and failed

PS3's Cell Broadband with 7PPE and XDR memory was very new tech with niche supercomputing in mind which kinda screwed them when it came to developing 3rd party games.

What makes you say PS4 is 15x more powerful then PS3? lol.

The jump from PS1 to PS2 and PS2 to PS3 is far larger than PS3 to PS4 will be...the saving grace really is the unified 8GB GDDR5 though which I can see them going for 7+ year console cycles again.

That was their initial issue, which got smoothed out in the end. Though your main point stands, the cell tech was never designed to be used in the way they used it. The biggest problem they had wasn't quite the cell, it was using the cell with a really crappy graphics chip. Oh whatever it was, as they had to end up using the cells to do some of the GPU bound work. This limited them in other areas that could have drastically expanded the ability of the platform. Just like the Xbox ran a tri-core, it's major downfall was when HT was on the chip apparently down clocked. I believe to keep energy requirements within spec, still at half the performance cost.

To put it bluntly, both consoles had hardware limitations that weren't originally foreseen. Even to the point where one company ignored a hardware flaw until a class action was brought to their attention, both companies basically lost a lot of money. So we saw them milk their product, because of their own failure. Which I think is absurd, we pay for their blunder, anyways. After both blunders, we see both companies move to traditional tried and true hardware. This time they don't want to waste the money on R&D, and they won't.

Strange, that history tought Sony nothing. They scored big time with PS1, cause it had simple and efficient architecture with easier development tools. The games looked very hi-end at the time (Crash Bandicoot for example). There was N64 with SGI GPU, Sega Saturn with dual-CPU, Atari Jaguar with semi-64-bit architecture... But they all were tough to program and utilize their full potential (and the tech didn't perform as expected, it was so new at the time). The console makers now finally realized that and stopped fumbling in the dark and playing e-peen game with hardware.
