Intel did some preliminary testing of Intel Celeron E1600 and compared it to Celeron E3300 series, and as you could expect, the new 45nm Celeron with 1MB cache and 100MHz faster clock speed ended up faster.
Both E1600 clocked at 2.4GHz and E3300 clocked at 2.5GHz and
FSB800 were tested on G31 motherboard with 1GB memory.
In HD Video Encoding in DivX 6.7 and VirtualDub 1.7.2 E3300
ends up nine percent faster than E1600. In Mpeg DivX conversion new Celeron can
do things 10 percent faster. In Audio MP3 Encoding in ITunes 7.4.2.1 new
Celeron scores 11 percent better score while in Game Physics and AI test from
3Dmark06 Intel claims 14 percent better scores.
The winner of the test is WebPhoto resizing test in Adobe Photoshop
Lightroom where the new CPU, thanks to 1MB of cache does things 34 percent
faster. Since these are Intel's internal data, always take them as the best
case scenario and weird test choice such as Game Physics test from outdated
3Dmark06 were there simply to make things look better for Intel.
The new E3300 and E3200 Celerons are expected in Q3 2009.
