Well, one could hope, however, here is what I am seeing:
My computer is a Hp pavilion dv7 4144ea.
ATI Mobility Radeon HD 5470
with 512 MB dedicated memory
2.20 GHz AMD Athlon II P340 (2 cores)
4 Gb RAM
17.3 inch Glossy LCD (LED-lit) (1600x900 px / 16:9)
IDT audio HD. With altec lansing speakers and dolby advanced audio
Windows 7 Home premium 64 bit.
AMD Athlon II P340 2.2GHz processor... This is derivative from the Phenom series AMD. If we look at this chart: PassMark CPU Lookup
My old Intel Core 2 Duo (E6600 @ 2.4 GHz) processor rated around 1506, the P340 rated around 1304.
And yes, this could be skewed, however, one of the things is, my Core 2 Duo was suffering some serious stuttering on some of the newer games, such as Call of Duty: Black Ops, Medal of Honor 2010 and, strangely enough, in World of Warcraft, due to CPU spiking. Of course, part of it was also due to background programs running such as Web browser connected to mail services and facebook or a lightweight feedreader trying to do RSS feed gathering.
The problem is, that some of the newer games are now pushing the limits of some of the older processors, hell, my old system was 4 years old and I was seeing FPS drops and stuttering. I used a Logitech G15 Keyboard and the SirReal LCD to show me what the CPU and mem usage and seeing the CPU literally max out during the times system was a bit laggy or stuttering.
Hence my suggestion to use a G510/G15 Gaming keyboard and using the performance monitoring while playing and look down at the screen to see what it shows for CPU usage.
Also, looking at the wiki for the Athlon II, it states:
The Athlon II series is based on the AMD K10
architecture and derived from the Phenom II series. However, unlike its Phenom
siblings, it does not contain any L3 Cache
. There are two principal Athlon II dies: the dual-core Regor die with 1 MB L2 Cache
per core and the four-core Propus with 512 KB per core. Regor is a native dual-core design with lower TDP
and additional L2 to offset the removal of L3 cache.
One thing to note is that the processor architecture is important to note. The lack of a fast L3 Cache and the lower processor speed will affect how well it will perform over all. Intel chips also have a much better 'brute force' method which is why they tend to do better than the AMDs and also why Intel charges more than AMD on a performance level.
Again, I mentioned my older Intel Core 2 Duo chip and citing the CPUmark rating to iterate that there is a possibility that the CPU could be the limiting factor. If my ailing Core 2 Duo which is benched slight better than the mentioned CPU was encountering the problems in question due to capping of the CPU, there is a chance that may be the culprit... HOWEVER, this cannot be confirmed unless you do empirical observations with a CPU Performance monitor while it is happening on his system.
