Sony PS4 Pro Held Back by The Outdated Jaguar CPU?
Sony recently announced the 4K-ready PS4 Pro with the most powerful GPU that offers double the performance over the predecessor. But it seems like the next-gen console could be held back by its outdated CPU and RAM bandwidth.
The PS4 Pro packs AMD’s latest Polaris GPU technology capable of 4.2 TFLOPS that is on par with a Radeon RX 470 in terms of power. This allows for upscaled 4K gaming and native 1080p @ 60fps. However, there are concerns over the 8-core Jaguar CPU which is the same piece of hardware inside the original PS4.
Although Sony has overclocked the CPU from its previous 1.6GHz to 2.1GHz, the component is essentially still the same that could bottleneck the GPU.
For the matter of fact, when Digital Foundry ran Rise of the Tomb Raider on PS4 Pro, the game couldn’t hit a consistent native 1080p 60FPS. Apparently, this is down to CPU bottlenecks, but Digital Foundry also notes that the console’s 8GB of GDDR5 system memory doesn’t seem enough and could compromise upscaled 4K textures.
On the one hand, this highlights a fundamental weakness with PlayStation 4 Pro. Even though developers have access to another 512MB of RAM (presumably swiped for the vast 3GB system reservation), it’s not enough to accommodate the 4K texture options that developers are increasingly offering with their titles.
So in the case of Rise of the Tomb Raider then, it’s no surprise that the PS4 Pro version offers assets in line with the existing Xbox One game, equivalent to the high texture quality setting on the PC build. It’s a definite limitation–but on the plus side, in terms of this title at least, the downgrade is only really an issue in cut-scenes.
This is disappointing for potential buyers of the PS4 Pro that are hoping to achieve native 1080p 60fps in AAA titles after all. They’ll have to wait for a year or two until the company reveals the PlayStation 5, or whatever it would be called, that could support native 4K gaming–just like Microsoft’s upcoming Xbox Scorpio.
Sony PS4 Pro is set to launche on November 10 for $399.
