Recent PS4 SDK update unlocked 7th CPU core for gaming

What cellphone do you have that has a better CPU than PS4?

Well, I already notice varying home screen performance depending on which game I run.
For example, when I'm playing Arkham Knight or MGSV, I notice that the home screen runs quite a bit more sluggish. Not so with other games.

All that power
isnt used only while stand by mode?
Sleep mode functions I believe.
That thing is just weird. It was supposed to handle background downloads. But then it turned out too be to weak even for that. How can you find a processor with 256MB RAM that cannot even handle a HTTP download. As a result, the APU has to run with the fan running at low RPMs for background downloads of games and patches.
This generation is pretty weird, yeah. Everything gets a PC version and sites exist dedicated to testing the console versions in depth to see how they compare to the PC version. Games and game consoles have never been under such widespread scrutiny.

Note 6 has a 1.9GHz processor. PS4 only has 1.7ghz
My old Pentium 4 from 2004 is more powerful then the PS4 CPU.
This is totally how CPU's work right?
The actual die is bigger afair because of the esram.
You missed completely the sarcasm and I found the comparison really stupid.
Yeah that's not my read. The only thing I imagine that's comparable is the iPad Pro, Air 2, and The nVidia K1/X1. But those have a lot bigger form factor to dissipate heat and provide for a larger chipset and battery to power it. Not to mention I'd imagine the costs are much higher though I'm too lazy to check out and compare teardowns. Even then I'd imagine they would drop off quickly once they throttle down what with being passively cooled and all.
Security, DRM, secure boot and the recording stuff nobody talks about anymore.
I almost thought you was serious lol.

yes but the Pentium is only a single core n? PS4 has 8 cores in tandem. But your phone definitely outclasses it and future phones will at least be 2x-5x more powerful before even mid-gen.

Apple's Twister CPU cores offer over 2x the performance of AMD's Jaguar.
Wait, what? So the per core power is twice what the jaguar is capable of? I mean yes, the cores are shit but not that bad.
Any proof for this?

So does this equal to a CPU performance increase of 16.6% or is the math not that easy?
It is called playing safe. This just means that the software ripes when it arrives at the customer. Optimizing the os and other software can happen later but at first you have to offer a working system.

Going off of geekbench which isn't the end-all obviously, but yeah Jaguar was a decently impressive mobile cpu architecture in 2013 and Twister is a really impressive mobile cpu architecture in 2015.
Batman Arkham Knight
Witcher 3 (after latest patch)
Assassin's Creed Syndicate
All already running with better framerate on PS4, so I'm not sure why it needed any help for open worlds in the first place.

It is indeed not linear. The actual end gain depends on many factors.

Out of curiosity, how do you compare the performance of two processors using a simple fact sheet?
Clock speed, number of cores and...?
Not even remotely. These resources are to be seen in context with other resources in a system with many components. These this don't just add up.

YES!!!!
Not that easy. We don't know how much of that core performance is avaiable to the devs.
7th Xbone core is shared between games and OS services [game gets more].
The IPC is totally different so Ghz values aren't really relevant when comparing across different chip architectures. Especially designs that are separated by more than a decade of efficiencies and manufacturing advancement. Comparing an early 2000s CPU to anything sold today by using that metric is about rational as arguing that my cordless home phone is faster than the PS4 because it transmits on the 2.4Ghz spectrum.
Ok... not quite that bad... but still 
Uh...they aren't just 'locking away' cores. They were allocated toward OS just incase they needed them. You don't just get resources from nothing. Optimization is shuffling things around, removing and streamlining.
For PS4's CPU, they just moved the one of the CPU cores dedicated to OS to gaming instead.
Is it 100% of the core? That would be better utilization than MS's seventh core, which is only partially available, although clocked slightly higher. Although i think the partial utilization was due to the snap and kinect functions, whereas Sony has no such functions to hold back 100% utilization

You can never have enough memory. Especially for a closed platform, where you know exactly how much you can use. And even more so when it's graphics memory.
Again, I want to see actual data. There has to be something wrong, no matter how impressive the twister is.
I'd like to see me too because I'm not quite convinced of such comparison.
Why thinking competitive? Better doesn't mean good. AC still still drops, doesn't it?
Not really, that core is what? 1.6ghz?

Looked it up after not believing myself. It's it's actually in striking distance of some low-mid range Intel CPUs like in the entry level Surface.
Here's a page that lists them by device and uses 2500 as a baseline simulating roughly an Intel i5-2520m. The iPhone 6s+ and 6s score about 4300.
Ability to perform a given task. You really can't compare processors without knowing the task at hand.

A9X can certainly hold its own in benchmarks, especially considering the constraints of a slim tablet packaging. That said, it's just GeekBench, it'd like to see some real-world comparisons before making that declaration.

The A4-5100 has 2MB L2 cache and runs at 1.55 GHz, the PS4 has 2MB L2 cache (x2 between the 2 4core modules) and runs at 1.6GHz so if you look at single-core benchmark results for that chip and round up a little bit you should be getting a pretty decent idea of what the PS4 cpu is capable of. Then you can compare that single-core performance with various other CPUs out there to get a general ball-park comparison. The Jaguar cores tend to hover around the mid 800s where as Twister cores tend to hover around 2500.

Not exactly scientific definitive measurement, but it's a start.
Do you have a phone with 4 Twister cores?
