***AMD Kaveri APU quick look***

[stulid]

Here is a quick look and some tests of the new AMD Kaveri APU's, I have here the top end A10-7850K and lower A10-7700K.

In the box is your warranty guide, case sticker and small heatsink+fan with pre-applied paste.


Both these APU's are black editions and have an unlocked multiplier as denoted by the "K" in their model name and feature four new Steamroller cores and GCN IGP gfx.

Below are CPU screenshots of these two new APU's and a previous generation A10-5800K (Trinity) APU which uses Piledriver cores at their maximum turbo frequency..

*Ignore the 0.4v Vcore of the A10-7700K as I think I grabbed that screen as it was about to throttle down under Cool 'n' Quiet.

Test setup.

A10-5800K
A10-7700K
A10-7850K
Kingston HyperX (2x4GB) 2400MHz RAM
Gigabyte A88X Sniper
Kingston HyperX 240GB SSD (RAID0)
Catalyst 13.35 beta17 drivers.
Windows 8.1

First test is CPU-Z at stock speeds.

Next up are some games,

BattleField 4,

•1920x1080 Medium Preset​

•1680x1050 Medium Preset​

Hitman Absolution,

•1920x1080 High preset​

•1680x1050 Medium Preset​

Bioshock Infinite,

•1920x1080 High Preset​

•1680x1050 Medium Preset​

Tomb Raider,

•1920x1080 High Preset​

•1680x1050 Medium Preset​

One thing to note is that I can test Bioshock a thousand times and the max fps report varies constantly, the minimum and average fps remain constant.


Next are some synthetic benchmarks,

For Unigine Heaven4.0 and Valley I used the same settings as used in the forum threads found here,

Very stressful settings for a little APU to cope with.

Next is 3Dmark Firestrike, the full benchmark can be found here.

Next is Asus Realbench2.0 which can be found here.

X264 was ran, you can find this benchmark here.

PCMark 07,

Catzilla 1.1 was next up running at 720p from Here.

Cinebench R11.5

Cinebench R15

3D mark 11,

PC Mark08,

Overclocking.

Using the Snipers BIOS I managed to get the A10-7850K to a stable 4.4GHz by adding +0.054v to the Vcore and setting LLC to medium.

Of other note is that to get the A10-7700K to work perfectly with the RAM at 2400MHz it required +0.036v adding to the north bridge voltage, the A10-5800K and A10-7850K required no such adjustments.

Thanks to Ethermaster for the graphs and banner.

 

[stulid]

do some x264 encoding tests please.

I have, look at the charts.

 

[stulid]

i mean proper benchmarks, 720p and 1080p and compare it to haswell versions of pentium, core i3 and core i5.

You buy me haswell versions of the pentium and i3 etc then I will.

 

[stulid]

This is the cTDP function, allows you to limit the APU to 45W or 65W.

 

[stulid]

Can it get any higher for benching? Or was 4.4GHZ the max you felt comfortable with?

That's a value it passed everything at.

It can do 4.5Ghz on some tests but then freeze up during Realbench.

Maybe more Vcore may help, but I ain't putting a stupid value into the BIOS.

 

[stulid]

nice, what are cpu and gpu frequencies when you lower it to 45w?

This I can do for you,

Its switching between 3GHz,

To 3.5Ghz,

Vcore according to CPU-Z has taken a drop also.

Wonder what this does

 

[stulid]

How does it run BF4 at 720p? I'm thinking of putting one together for a mate.

I can do that, give a few mins (more like 30)

 

[stulid]

Nice, thanks. These apus are only really good for 720p really I think with the limited bandwidth they have.

This is directly comparable to the results above as I used the same test section.

**Kaveri in as fast as i7 920+GTX470 shocker**

Thats headline material right there.

 

[stulid]

I don't know if this was answered in another thread, but do we know which dedicated GPUs can be hybrid x-fired with these Kaveri APUs?

I would like to upgrade my HTPC at some point this year to something with more grunt than the 1.6GHz Atom machine I have now. I was thinking along the lines of getting an A7850k to begin with and then adding another card later to boost performance.

It's been answered, you can use a 240 or 250 GDDR3 card.

 

[stulid]

Just been playing BF4 multiplayer at 1440x900 with medium settings.

It was fine.

 

[stulid]

Impressive for the A10. Stulid, what score is achieved on the overclocked 7850k on 3DMark11?

I will get round to doing this when i put Win8 back on, currently been messing around with Win7.

 

[stulid]

Couldn't take it much longer so have fitted a R9 280X to get the in-game settings back up to what I'm use to.

 

[stulid]

Before you get to excited this is with a R9 280X added.

PC Mark08 now added.
