TR reviews the Core i7 4770R:

http://techreport.com/review/26166/g...pro-reviewed/3

The numbers for the A8 7600 look decidedly low when compared to other reviews:

http://www.anandtech.com/show/7677/a...0-a10-7850k/12

Having said there is evidence of Intel cheating with texture filtering.

Some details of Carrizo:

So it seems the earlier SOC and DDR4 rumours are true,and the CPU will use the FCH on the motherboard in the FM2+ version,instead of the one on the chip.

why are they tesing (on TR) against an A8 and not an A10?


edit:

love this part

The Brix Pro's Core i7-4770R hits 100°C and clearly throttles its clock speed in order to avoid heating up beyond that threshold

and yet they don't prime the A8....

TH tests Thief with Mantle:

An FX4170 just about matches a Core i7 4770K!

Further tests with an A10 5800K:

I've always been skeptical about tom's hardware reviews but at least they are including results with the FX 8350 and FX 4170 to provide some pertinent comparisons in their charts for Mantle. It is alarming to see the laziness in some review sites.

Losing 8 lanes of PCIe to the graphics slots seems a bit drastic! I guess that is the penalty for the tight power budgets on modern devices, those PCIe 3 lanes are supposed to eat quite a few watts.

Just noticed looking at AM1 motherboards on http://www.anandtech.com/show/7869/a...19v-dcin-model

That the cpu only has 2 mounting holes for a heatsink & fan. Graphics card standard mounting perhaps?

Would be nice if fans like http://www.scan.co.uk/products/north...d-ati-see-info already fitted.

An interesting graph (AMD provided, pinch of salt application at the ready) on SA http://semiaccurate.com/2014/03/18/a...version-thief/



Ignore the Mantle line, look at the others. Low end CPU, the Nvidia card is clearly the one to have. On the i5, you are far better off with the AMD card. You don't normally see CPU scaling against cards, so interested me.

I wonder if Trueaudio can run on a Kaveri APU with a non-Trueaudio card present?

It seems the first Bay Trail Atom based motherboards are available in the UK:

Dual network ports with only 2 sata ports? £77, are they having a laugh?

It appears BT is not as cheap as some expected it to be!!

A chap over on Anandtech forums tests one of the Athlon 5350 APUs:

However,he is using a unknown brand 350W PSU,so power consumption is probably higher than it needs to be.

Edit!!

It seems the socket AM1 CPUs range from around £26 to £40 on Amazon:

More pictures of the CPU and the stock cooler:

Interestingly his Cinebench scores are the same as I got for a Sandy Bridge Celeron G540; 160 and 1.94 for R15 and R11.5, respectively.

Clearly based on an industrial design (note the twin serial ports). £77 for an industrial mITX board's actually pretty reasonable. The dual core one at £50, with mini-pcie and full PCIe x1 slot, plus sensible array of IO, looks quite reasonable - shame it's got the lesser chip. That board + the quad core at £60 wouldn't be a bad deal...

Interesting article on Phoronix about Linux drivers

http://www.phoronix.com/scan.php?pag...tem&px=MTY0MDY

Unless the Windows drivers are also done in Shanghai then the developer location is a bad thing. Development done right means that release notes just fall out of the process, so it sounds to me like they don't know how software quality works. Legacy driver sounds abandoned rather than I thought it was just badly lagging the main driver.

It just all sounds sloppy to me.

On the up-side, a few clicks from there was a link to the slides from that talk on making OpenGL go really fast. Lots of slides, only had a chance to read the start but seems good so far:
