The Open-Source Linux Graphics Card Showdown

[smitty3268]

Hmm, can someone (preferably an Intel dev) confirm that? If I'm wrong, I'd like to know, so that I won't be saying wrong stuff in the future anymore.

No, i'm pretty sure starting with Sandy Bridge it's 1 chip on 1 package.

There is just a pipe between the 2 sections of the chip, so communication between the 2 is exactly the same as if it was on a different chip, but it's built as one.

AMD iGPUs are the same. Actually, not quite - Sandy/Ivy Bridge share the L3 cache with the GPU, while AMD doesn't have that ability. Unless Trinity adds that, which it might.

Eventually they will get better integrated, and you'll probably see things like the CPU transferring floating point operations onto the GPU hardware, but i don't know how far out that is.

could we have comparison between Ivybridge OGL linux and Windows drivers? Some time back there was such comparison provided on phoronix for sandybridge and it was very helpful. Thanks!

I found info here on geeks3d.com that Ivybridge Windows driver supports OGL3.3. Do you see same result?

Thanks again!

I think only SNB shared the 3rd level cache, IVB does not.

Obligatory post making fun of some random typo in the article that will never be corrected:

Holy thermo-nuclear GPU Batman!! The Radeon HD 4670 idles at 766 Watts??? Surely it must produce a truckload of heat

Colors are funny things to work with mathematically. The main thing you need to keep in mind is that you have to treat colors as THREE numbers, not just ONE.

It's worth remembering that there are different ways to represent colour: the way you are describing is the RGB colour space, and should be treated as 3 separate numbers for (hopefully) obvious reasons. If you use the HSV (Hue, Saturation, Value: https://en.wikipedia.org/wiki/HSV_color_space) colour space then it is reasonable to fix the saturations and values and choose equidistant values for the hue.

Well I guess this almost Finalizes my next build sorry AMD looks like I am going with intel .. that on-board GPU does what I need ( VA API)
and runs doom3 as a bonus to boot
which means any game I would play .. should work ( UT2004 ect )

but I will still wait for AMD A10-5800K release .. but it doesn't look good for AMD with their driver support

I hope their will be another good linux test i7-3770K vs A10-5800K

looking for lowest power with full support as HTPC

and something that can do my media encoding

Nice test, but I think it's near impossible to tell which curve corresponds to which graphics card in those graphs. The colors are way too similar.

If you move the mouse over any line, it shows which card it corresponds to. If you have fairly modern browser and get SVG served, of course.

I stumble over this typo and found your report in the forum.
Which power supply can handle such an idle power?
The cooling system must be hot as a hair-dryer as loud as a plane.
