New XTU version? - XTU is so much fun^^

slow mode no need

Newest XTU version for sure Websmile, and yes Max OC, slow mode no need.

New version is +30pts with 300 mhz lower?

New version is +30pts with 300 mhz lower?

I think it's much worse than that, new version seems very efficient, in comparison but much harder to pass.

Sandbags are full on this end

Wild guess, but could you check if this new XTU version uses AVX? Prime95 was updated a long time ago to support AVX, but the first version of the benchmark was developed with an older version not supporting AVX. Maybe check the version of the Prime95.exe in the XTU folder.

Switching to an AVX version would explain the increased "efficiency" as well as the increased load.

Also shot an email to Intel about this. Would be helpful if they give a heads-up or so LOL.

Ehem, this might be it

Prime95 version 28 released! Faster on Intel's latest CPUs!

 

June 1, 2014 — Version 28 is now available for download. The FFT assembly code has been optimized to use Intel's fused multiply-add instructions on Intel's Haswell CPUs (Core i3/i5/i7-4xxx models). Haswell users should see a decent performance increase. Sandy Bridge and Ivy Bridge users may also see a small speed boost due to some memory bandwidth optimizations. To upgrade, simply exit Prime95, download the new version, and unzip the new version replacing the old version.

So I assume we have to use the newest version of XTU correct? Most contests seem to specify a version which is usually the latest one, but would like to clarify for overall rankings.

Once we get the confirmation from Intel we can see how to deal with this.
