These AMD processor revisions are being released against a backdrop of Intel domination. AMD’s aging K10 architecture, clock for clock, simply can’t compete with Intel’s current range of Core i3, i5 and i7 CPUs. It’s with a degree of trepidation, then, that we take a look at AMD’s new flagship Phenom II X6 1100T Black Edition CPU. As our more canny readers may be able to tell, the 1100T BE is a revision of the Phenom II X6 1090T Black Edition, meaning the 1100T is a 6-core chip based on AMD’s Thuban design. This design is still rooted in the K10 architecture, but has a number of improvements over AMD’s previous CPUs, most notable of which is AMD’s Turbo Core technology. The 1100T BE doesn’t suffer from a lack of raw speed, though, as it’s clocked at a zippy 3.3GHz. With Turbo Core enabled AMD claims the 1100T BE should hit speeds of up to 3.7GHz in single-threaded applications. We saw the CPU attain these speeds when we loaded a single core with Prime95, though it only managed to hold the speed for about 15 seconds at a time. This is presumably because other background Windows applications demanded some CPU time, meaning more than one core was being used. Our previous overclocking experiences with AMD’s 6-core chips have been pretty variable. Our look at the AMD Phenom II X6 1090T Black Edition showed the CPU to be a competent, rather than spectacular overclocker, reaching a final clock speed of 3.87GHz. We were hopeful of being able to push the 1100T BE a little further, as AMD’s Thuban die is now more mature, which hopefully means that there should be more overclocking headroom. Thankfully, the 1100T BE didn’t disappoint, as we were able to push our test chip all the way up to an impressive 4.2GHz. This represents a healthy 900MHz overclock, which is significantly better than the 670MHz overclock that our 1090T BE managed. To achieve this overclock we raised the HTT to 300MHz and set the CPU multiplier to 14x, but to keep these settings stable we had pump a beefy 1.512V through the CPU. We also raised the CPU/NB voltage to 1.35V and the HT voltage to 1.35V while supplying the Northbridge with 1.3V and the Southbridge with 1.2V. Performance Analysis The Phenom II X6 1100T Black Edition started strongly in our raft of CPU tests, though we were expecting this as the first few tests we run are heavily multi-threaded. The chip excelled in Cinebench R10 for example, scoring 18,821 at stock speed which is just a whisker behind the 314.81€ (£230) Intel Core i7-950. It also performed well at stock speeds in WPrime, though curiously the CPU that the 1100T BE is due to replace, the slower 1090T BE, was slightly quicker in this test. Naturally our 4.2GHz overclock bumped these scores up a fair amount too - the 23,624 the 1100T BE scored in Cinebench when overclocked represents a 25 per cent improvement which is a great result. WPrime saw similar improvements, with the 1100T BE skipping ahead of even the i7-950 when overclocked. Unfortunately, results were a little less spectacular in our Media Benchmarks. The 1100T BE’s score of 1,181 in our image editing test was behind even mid-range Intel chips such as the 191.62€ (£140) 2.8GHz Intel Core i5-760. The 1100T BE was a fair way up the performance table in the heavily multi-threaded video encoding test, but it was poor in the multi-tasking test. These results combined to give the 1100T BE an overall stock speed score of 1,442. While this is faster than its forbear, the 1090T BE, it was way behind similarly priced Intel chips such as the Core i7-930. The 1100T BE’s relatively impressive overclock helped matters, but given that the Intel CPUs it compets with also overclock very well, it was always going to struggle to overhaul the gap. The Overall Media Benchmark score of 1,727 is an impressive 20 per cent improvement over its stock-speed score, but even this improvement was eclipsed by the Intel chips. The i5-760, for example, saw a 40 per cent increase in its overall score when overclocked. Power consumption figures for the 1100T BE were broadly in line with our expectations. The chip consumed a little more power than its slower sibling, the 1090T BE, at stock speeds but significantly more when overclocked. This isn’t such a surprising result given that we applied a little more vcore to the 1100T BE than to the 1090T BE. If we were judging the 1100T BE in isolation you’d probably be seeing a big shiny gold circle just a few inches below this paragraph. The CPU improves on the previous 1090T BE at stock speeds due to its slight clock bump, and it also proved to be a lot more overclockable than the older chip.Vollständige Rezension lesen

Läuft stabil, ist schnell unterwegs mit den richtigen Komponenten. Vor allem zum übertakten gemacht. Mit dem Turbo Boost ist einiges rauszuholen.
Bestätigter Kauf: Nein
Perfekt. 😀
Bestätigter Kauf: Ja | Artikelzustand: Gebraucht
very good

Der Prozessur hat wirklich gute Eigenschaften. Meiner hat sich Automatisch auf 3,7 GHZ Eingestellt mit guter Temperatur. Natürlich kriegt man für 100-120 Euro auch etwas Bessere nur muß man dann auch noch 100 Euro für ein neues Board ausgeben.
