New system - which GPU
on May 30, 2014 at 10:19:35 pm

Hey All,

Building a new system now, and I can choose between my GTX 460 (768MB) and my Radeon HD 6870 GPU's. I know the 6870 is faster, but are there issues with using them with an Intel chipset?

This is the new system:
MSI Z97 PC Mate
Intel Core i7-4790 Haswell
HyperX Fury Black Series 16GB (2 chips)
SAMSUNG 840 EVO MZ-7TE120BW -SSD
and other parts

Again, mainly asking for how AMD GPU's work with Intel MB's. I have used AMD CPU's for the last 3 interations of my main system...

Thanks again for your input!!!

AMD graphics cards work perfectly fine with Intel processors. I run a Radeon HD7850 with my Intel Ivy Bridge processor and my system runs like a McLaren MP4-12C.

That was what I expected...but just wanted to confirm with several people. I vaguely remember there being issues early on....but wasn't sure at this point...

Thanks!

You have to remember that AMD bought ATI so these are ATI cards that are now labeled AMD. They have nothing to do with AMD motherboards to processors. Apple ships AMD GPU's on every Intel computer it has. I've never heard of problems with AMD GPU's with Intel CPU's or motherboards.

Perhaps you're remembering back to the SLI vs. Crossfire days? If you had a Crossfire motherboard and you bought in SLI GPU it wouldn't work in dual card mode. Even then it always worked with a single card. That's the only incompatibility I can think of.

Thanks John, that could very well be what I was thinking...Again this would have been SVP 11 when GPU was just starting to be supported.

So, you would recommend the 6870 than I supposed?

Also, is the intel 4000 and 4600 GPU an AMD chip on my Mac mini and also my Macbook Pro?

Thanks again for your input!!!

The ATI Radeon HD 6970 is the latest card that works with GPU rendering. Cards from the 7000 series and beyond will only accelerate the timeline playback but don't seem to work with the MainConcept AVC encoder which I use a lot.
[Scott Francis] "Also, is the intel 4000 and 4600 GPU an AMD chip on my Mac mini and also my Macbook Pro?"
No, the Intel chips is by Intel and has nothing to do with AMD. Vegas Pro also has support for some Intel HD chips as well. I have the Intel HD 4000 on my MacBook Pro but I don't use Bootcamp on that computer, only VMware so I don't know if Vegas Pro would recognize it under Bootcamp. I only use Bootcamp with my Mac Pro and that has an ATI Radeon HD 5870 that Vegas Pro uses under Bootcamp.

Thanks John,

My initial post was for me to pick from two cards I already have. The 6870 and the GTX 460 (768 MB). The 6870 has better specs, but wasn't sure if it always "plays nice" with Intel boards. I was just confirming that you recommend the 6870 since you said AMD is fine on Intel boards.

Apple ships AMD GPU's on every Intel computer it has
.

This confused me and I was asking if the 4000 and 4600 GPU's were NOT Intel chips, since all the Macs I have use this. Vegas DOES see the 4000 chip on my Macbook in Bootcamp. It isn't great, but it can use it.

Thanks again for all your input, I will go with the 6870, the CPU has an intel 4600 chip onboard, by the 6870 is much better than that one!!

Have a great day!

Yes, the Radeon HD 6870 is fine and will work much better than the GTX 460.
[Scott Francis] "Apple ships AMD GPU's on every Intel computer it has. This confused me and I was asking if the 4000 and 4600 GPU's were NOT Intel chips, since all the Macs I have use this."
Sorry for the confusion. That was too general a statement. Apple does ship some of it's computers with two GPU's. They use the Intel HD chips for low power consumption and they use NVIDIA and AMD for high power graphics. This changes dynamically as your peer needs change. Apple has flip flopped back and forth between including NVIDIA and AMD GPU's with their computers. Right now the most powerful Mac Pro's have AMD FirePro's in them. Earlier Mac Pro's had AMD Radeon HD 5770's and 5870's. My Mac Pro has the 5870.

Sounds like a plan.

Hi John,
I ordered that HP z420 with a Xeon 6-Core E5-1650 v2 3.50GHz I had asked about. It was 47% off, so I figured it wasn't worth waiting for a better deal.

I now want to get a GPU for it just for preview. I see lots of R7 250x and 260x cards around new for $95-110, and the 6970 for only a few dollars more. On AnandTech's Vegas rendering test the 260x and 6970 are close, the 250x is a little slower, but uses significantly less power. Power use was around 190W, 223W, 314W on those 3 cards on their FurMark test.

Since I'm only going to use the GPU for preview, is it safer to go with the lower powered card for system stability and less heat? Between the 250x and the 260x, it almost seems like I should just go for the 260x since they're about the same price, but I wonder about the wattage given the power supply is only 600W.

I would go with the 260x because there is not that much difference in power between 190W for the 250x and 223W for the 260x. The 260x does have this requirement:
500 Watt Power Supply is required.
1x75 Watt 6-pin PCI Express power connector is required.
So make sure that you have a 1x75 Watt 6-pin PCI Express power connector on your power supply before buying.
