PS Magazine 'build a PS4' with the rumoured specs
Perhaps, you remember the rumored PS4 or Orbis details. All indicates Sony wants to power their next gen console with PC parts.
The rumored specs include an AMD A8 3850 processor and AMD Radeon HD 7670 graphics card. Well, the Official PlayStation Magazine UK built a PC with some of these parts, and compared it with a 'high end' PC, which included a Core i7 2700K CPU.
The AMD A8 3850 processor belongs to AMD’s ‘Llano’ range, designed to handle both the usual CPU tasks and deal with graphics – it’s aimed at those who want to save the pennies and go without a graphics card.
As you’d expect then, it’s priced low – available at a pinch over £100, and it’s raw operating speeds aren’t that impressive. It runs at 2.9 GHz across four cores – for reference, the PS3′s six-year-old processor runs at 3.2 GHz across essentially four of its availible 6 cores.
The Llano processors are good at what they do – offer a cheap ‘all in one’ graphics and CPU solution to those on a budget, but when we’re talking about the next generation of consoles it seems odd for a chip like the A8 3850 to be in the picture at all.
Well, it didn't do too well on benchmarks:
They also tried a couple of games, like Just Cause 2, Bulletstorm and a beefed-up, super-HD texture version of Skyrim:
Cinebench R11.5 scores:
Our homemade ‘PS4′ (AMD A8 3850) 3.42
High end PC – (Intel i7 2700K) 7.02
So the high end PC recorded a much bigger score, rendering the image almost twice as fast as our PS4. It doesn’t smack of ‘next gen,’ the reported hardware powering the Orbis.
Just Cause 2 PS4 Frames Per Second: 21
With the Quasi-PS4 up and running using a complex system of rubber bands and lolly sticks, we ran some of the most demanding games (for PCs and PS3s) out there, starting with technically challenging open world liberate ‘em up Just Cause 2:
So in raw numbers, the test rig didn’t exactly knock our pants off (that’s the saying, right?). In fact with an average frame rate hovering just above twenty, the PS3 looks positively sprightly in comparison – according to Digital Foundry it renders JC2 at between 20-30 fps.
Bulletstorm PS4 frames per second: 30
Right, well this is more encouraging. 30 fps is perfectly playable, and the difference between PS3 and our test rig is really clear. The ground textures are sharper, explosions are crisper, and there’s a nice depth of field effect in the ‘PS4′. The two videos aren’t night and day, but there’s clear if subtle progress.
Even if didn't do too well using the PC versions of these games, seems that PC components in the current crop of Windows-compatible games wont give you much of an idea how a PS4 utilising those components would actually perform:
Skyrim PS4 frames per second: 27
Wow, that’s close. Frame rates look close, texture details looks close, draw distance too. One element that does set the two apart is the volumetric lighting in our ‘PS4′ video – there’s a thickness and depth to the fog and cloud, giving the sky a realistic quality. You can also see more of a sheen to the carriage driver’s leather garments in the ‘PS4′ version. It’s practically a photo finish in terms of detail, but it’s a bit disappointing to see the frame rates ducking below 30.
Also, the final hardware could change:
Coding on closed-platform devices, like consoles, means you can squeeze every last drop of performance out of the hardware because you know that every one of those devices will be exactly the same.”
So we could have done the same thing with the PS3′s equivalent PC components, run some benchmarks, and yielded much lower results, simply because the mass-market PC parts aren’t designed to work together and with nothing else, James says:
“On such an open platform as the PC that means coding in redundencies for myriad different components. So as much as us tech geeks like to talk about the slick bits of silicon inside the machines so much of the final product is dependent on the software that is created and actioned on it.”
You can check the full article below, which is pretty interesting and includes a few video comparisons. Well, at least it gives us an idea on what we should expect next-gen!
“There is also the possibility that the rumoured specs are based on the builds for the PS4 development kits which might have gone out. The final PS4 itself might contain more up to date iterations of that hardware further down the line.It should be possible to code with that current spec knowing that things are set to be x times faster by the time the final machines are released.
