Question

Will AMD A10-6800K bottleneck MSI Radeon R9 390 Gaming 8GB G

by Nov 25, 2015 7:02AM PST

Hi! I have AMD A10 A10-6800K black edition.
I need a new GPU to power the consumer Oculus Rift.
Found this card, MSI Radeon R9 390 Gaming 8GB GDDR5. It looks very beast. But, is my CPU too bad? Do I need to upgrade it?
Oculus says i need an Intel i5-4590 equivalent or greater. How is my CPU compared to the i5-4590?

Please help, I really want a good gaming/VR setup but I dont want to upgrade both CPU and GPU because the Rift is also expensive Grin

Hit CPUBOSS.com to compare the CPUs. It's not just the CPU that matters but the bridges.

Let me try that again

As per benchmarks your cpu is a little light.
How will that effect Rift?......beats me.

Ram.
It might be best to have a 2x8GB@2133 kit installed and set up for dual channel.
That will help move things along.

Cpu.
If you stay with the APU series there is no great upgrade path.

Specs

I am currently running 2x4GB RAM, but according to Oculus that should be enough. But if I go for an r9 290 4gb, would that give me the same results? It is a lot cheaper because I can get it used.

My A10 is a bit weaker than the i5, but do you think it will still be powerful enough for the Rift? If I need to change CPU I would like an Intel so I need to change MOBO and RAM, so it gets a lot more expensive to do that....

What is your opinion?

This one

ASUS Radeon R9 290 4GB GDDR5
Is this one better?

My opinion

The specs that Rift is putting out are the 'minimum' required.
The 290 meets the specs.
The 8GB of ram meets the specs.
Your A10 is light.

How well that package will run VR is unknown to me.

Your right about a switch to Intel being expensive.
Also consider your talking about a total reload.
Have some good backups of your stuff.

How light?

You can help this along by sharing your comparison at CPUBOSS.

If you want to compare GPU's, nod to GPUBOSS.

Might be OK.
by r. proffitt Forum moderator Nov 25, 2015 11:16PM PST

My bet is it will run OK. Why?

1. http://cpuboss.com/cpus/Intel-Core-i5-2500-vs-AMD-A10-6800K
2. "Our tests demonstrate fairly little difference between a $225 LGA 1155 Core i5-2500K and a $1000 LGA 2011 Core i7-3960X, even when three-way graphics card configurations are involved. It turns out that memory bandwidth and PCIe throughput don't hold back the performance of existing Sandy Bridge-based machines. "

So the old i5 I noted was driving 3 GPUs. You'll only be installing 1.
