Is the PS4's GDDR5 cause for concern?

post #1 of 20
Thread Starter 
I was seriously thinking about getting a PS4 for Batman and Watch Dogs. But going over it in my head, I can't justify spending $400 on a system that plays the same games as my PC. Then I keep thinking about the GDDR5 RAM. Is the PS4's GDDR5 RAM cause for concern for PC gaming?

I figure it isn't because GDDR5 is basically DDR3 with different methods of doing things, plus my video card has 2 GB GDDR5 on it as well. My 8 GB DDR3 is 1600 MHz and I don't think the speed increase for the GDDR5 is going to warrant spending that much money on the PS4.

But am I wrong? I feel like I am wrong.

What exact concerns would you have, aside from some vague misunderstanding?

From a GPU perspective the PS4 is still a 7850/7870ish class unit.

And the last I heard, a 7870 is not worth $400 bucks! wink.gif
Just play it on the 780 Ti's! Only issue with PC might be the CPU overhead!!
You can bet your life that Watch Dogs will perform like utter trash!

Somewhat. While the GDDR5 is used as both system memory and video memory, it's the PS4's somewhat low clock processor that is more a cause for concern for devs especially. Not to mention 2gb of that GDDR5 is already reserved for the PS4's OS.

How would GDDR5 be a cause for concern? It's way faster than DDR3, no?

And if you already have a PC capable of playing these games.. why buy a console for these games??

I'm confused on what the issue is here. lol

My rig in my sig was a joke. There is no way I can afford 4 780s. I have an fx 8350 and hd 7870. I just figured that the PS4 is more capable of playing these games since the games seem to be designed around their hardware. Watch Dogs will probably perform better on a PS4 than on my PC.

If your concern is whether you should buy a PS4 or stick with PC, stick with PC. The PS4 and Xbox one aren't even really able to play games at full 1080p a 60fps, its either 30fps or upscaled 720p-900p.

Actually the PS4 is capable of 1080p at 60 FPS as shown in the remake of Tomb Raider and Battlefield 4.

You don't have to worry about the PC CPU being slowed down by DDR3 compared to the PS4's CPU with its super high bandwidth memory. The PC CPUs are total beasts in comparison. They avoid memory issues through better caches. You can prove that to yourself by looking up what faster (overclocked) memory does on a PC for benchmarks (does not do much).

Additionally, the PS4 CPU is actually an architecture designed to be comparable to what's used in tablets or phones. The only difference is that the cores are probably clocked higher than what they would be like on a tablet because it has a good cooler and there's no worry about battery drain. That's why I mentioned the PC CPUs are "beasts" in comparison to the PS4 CPU.

And last point, the PS4 has to fuel its GPU with its fast memory and the CPU has to share.

Well you have to remember that both machines use x86 hardware. So now we can actually compare the ps4 closer to a PC than before.
