You always seem to be on the market, or maybe it's just my imagination
In any case, Trinity is supposed to be Q2.

Pentium G620 vs Liano...

I'm comparing the Intel G540 and it looks only slightly slower than the G620 which looks like the next step up.
For processing power, it beats the A6-3500 on practically anything so my question is how much power would a 'silent' video card add?

Originally posted by devius View PostWell, the Sandy Bridge Pentiums are in reality 35W TDP parts, although for marketing reasons (so they can sell more expensive "low-power" CPUs), they are branded as 65W. There are several sites out there that investigated the actual power consumption of these parts under full load and the results were between 31-37W. This means they don't get very hot and you can probably even underclock them, lowering power consumption even further and consequently noise as well.

Yes, it is a Lenovo IdeaCentre H420. I will try the full load test shortly.
I a completely silent room, you can hear the fan a bit, but the HDD is louder when it reads/writes
If you have any bit of background noise (TV, radio, people talking in next room, street behind window), you will probably hear nothing.

Any of you with Athlon IIs, is there much lag in p-state switching? (i.e. takes a noticeable amount of time for the cores to change clock speed in response to a computational load)
Intel CPUs since Core 2 Duo I believe have very minimal latency in changing p-states, as do AMD CPUs since the original Phenom. The old Athlons up to the 65nm X2s took about 200ms to clock up in response to a load, which was noticeable in general usage. That *may* explain the difference between an Athlon II X4 and a Sandy Bridge Pentium on the desktop..

Well, don't go for branded PC. It's more expensive.
Go for AMD X4 640 or G620. X4 if you want to maximize the core work (like VM, rip DVD, transcode, render, etc). Else, G620.
Agree with Devius. the open source radeon still no match for intel open source driver, for now. If you've spare money and go X4 630 route, take an cheap nvidia VGA card and you'll good to go.

@devplus: Thanks, your response is really helpful. If you imagine that on my PC the main problem is the desktop experience, (since the VM is a completely different thing), I think you helped me the most, as well as aceman.

I may be able to help you in the decision I hope. I have two systems that have some resemblance to what you're looking for.
One of those system is equipped with Athlon II X4 630, which basically has the same performance as the cpu part of A8-3800, installed on a 785G motherboard with 8GB ram and I'm using the HD4200 IGP. The other system is built around a Pentium G840 on a H61 motherboard and 4GB ram. Both of them are running Ubuntu 11.10. The Pentium is much more pleasant to work with mainly due to the better desktop experience provided by the GPU. For some reason (probably driver related) the composited desktop experience on the AMD system is terrible although the GPU is more than capable of handling it (I have to use Unity 2D to have a usable system). This is with both the open source and catalyst drivers. On proper fullscreen 3D applications the performance is as expected.
The Pentium is a totally different thing, with the desktop responding very smoothly and with very low latency. In terms of CPU power I don't really notice a difference because most applications are not well threaded enough. Even if they were it would only matter for certain workloads like 3D rendering. The problem here is not the CPU at all, but the GPU (and associated drivers).
For the type of workload you're describing, the Pentium will probably be the best choice. On top of the better experience you'll also be using open source graphics drivers so that should please the open source fanatics. Or not...
PS: The GPU on Llano is much more powerful than the HD4200 of my system, so the experience might be a bit better.Last edited by devius; 11 February 2012, 06:13 PM.
