A4-5000 vs T2500 Core Duo?

How's the A4-5000 CPU in an x140e compare to the T2500 Core Duo in performance? I know they're about 7 years apart and the latter is only 32bit. But just as far as snappiness in browsing and basic tasks, what might I expect?

Based on what I could remember about Kabini, it is approximately around the speed of an equally clocked Clawhammer. That isn't too bad, but a Dothan could easily keep pace with a Clawhammer, clock-for-clock.

On the Intel side, the Yonah Core Duo is essentially 2 die-shrunken Dothans in 1 die on a substrate with their L2 caches unified. Some minor additions such as SSE3 were also included, but that does not affect the overall instructions-per-clock in comparison to Dothan. Unless that specific application heavily uses SSE3 instructions.

As for the A4-5000 vs Core Duo T2500 comparison, I am afraid that I can't give a very accurate answer. I can only roughly guess that the A4-5000 would be no match for the T2500 in single-threaded operations, but the A4-5000 will be far exceeding the multi-threaded capabilities of the T2500. As in, something like a approximate two-fold boost in multi-threaded performance.

In basic tasks, such as what you mentioned, would be far more suitable and responsive for the A4-5000. This is only assuming that the latest features (4 cores are used properly) of the A4-5000 are used, though. However, in specific tasks that require better single-threaded performance, expect the T2500 to be slightly quicker.

Thanks, Screamer. I put in an eBay order for an x140e. I'm anxious to see how it does when I get it. No matter what, I'm sure it'll at least run cooler than my T2500 T60. :)

If the OS you use is like Windows 10 that has a nasty habit of running programs behind your back (downloading and installing updates), then a quad-core like the A4-5000 might be a better idea. Had Win 10 installed on an X61T (with 1.8GHz Core 2 Duo L7700) and the background tasks ate up an entire CPU core. :x Having a quad-core means losing only 25% of your CPU power, as opposed to half on a dual-core CPU.

Also, an SSD is highly recommended-- my mom has a quad-core Celeron N3160 laptop, which was slow as molasses with Windows 10 and HDD; upgrading the HDD to a budget SSD (WD Green 120GB) made it much better.

Well, the x140e arrived. I upgraded it to 8GB and put a 256GB Samsung 850Pro SSD in it. It's snappier than I thought it would be. Battery life pretty amazing, too. Although I much prefer the 1400x1050 screen on the T60, I'm still pretty happy with this unit.
