Did TPU review the "old" APU's? I don't remember.

But more CPU power would be nice, but on the whole I think these things are pretty well balanced for appropiate tasks. Like in HTPCs, desktops for avarage users etc.
I dont think TPU reviewed the old APUs:(
-----------------

I found this interesting review / preview/ leak? of the new Trinity APU.

The Trinity 4 core APU (4.2GHZ) faster clock for clock against Bulldozer FX 8 core (4.2GHz), which is good for a low end APU.

post #5

Sadly the guy from the original source has his calculated % in a strange way (not one of correct right ways, or maybe those numbers are for something else?)

Integer It is actually clock for clock 17% better than bulldozer (5800K vs 8150), and that is without L3 cache.


FP is 13% better.


Worked out by (numbers for 8150 vs 5800K, clock for clock):

INT: 1978.6/100 = 19.786
2327.4/19.786 = 117.6
117.6 - 100 = 17.6%

FP: 619.5/100 = 6.195
701.2/6.19 = 113.18
113.2 - 100 = 13.2 %

Which is actually really impressive, wow, if this performance comes true ill probably be looking to upgrade.

Two comments:

1: Dual GPU on a laptop is a dumb idea. The power usage of APU + retarded discrete GPU (rdGPU) is the same as pwoer usage of CPU (with no iGPU) + decent discrete GPU. The performance of ddGPU is much better and unlike rdGPU there are no CrossFire issues with driver support, weird performance drops, microstuttering etc. On top of that it is easier to cool two distinct components that both use roughly as much power, than to chill an unbalanced pair. Besides ddGPUs of today use astonishingly low amounts of power in 2D mode so there are no upsides to using APU + rdGPU in a laptop, only downsides.

It might be a different matter on a desktop where one might want to risk the small amount of money in hopes of getting better graphics performacne but not going all the way and splurging for a HD7750, but this article is about laptops.

2: Since Trinity dumped the braindead L3 cache of Bulldozer I take it's going to use less power for same performance level and suffer less from context switches due to "dumb schedulers" (it's always somebody else's fault when one's product doesn't perform well, right AMD ?). Is this a reasonable assumption or does the increased memory latency outweigh the benefits of getting rid of L3 ?

ummm have you used a APU laptop ever?
1. No the power cosumption is still less since you can switch off the discrete completely.
how less? an 6550G + 7450 on dirt 3 will last around 2hrs.
i played dirt 3 on that combo and it drained 20% of the battery after a little more than 20mins of play.

True the microstuttering is existent, but thats only a driver issue that needs time to be solved.

and power consumption is soooo low you will be amazed.

also contrary to what you think, its easier to cool an APU than two discrete things, since you need only one heat collection area, thereby making the laptop a lot lighter by eliminating heatsink weight.

i can use the apu powered lappy and game/stress on it, with it on my lap, without burning my thighs. Contrary an Atom gave me 1st degree burns while i was reinstalling its OS


true their CPU performance sucks, but the graphics and the cheap is more than good enough for most people.

The have capability of Crossfire or SLI with A75 Chipset

he just wants to bitch about it aka be the troll he is like a few other users here. APUs design was a good Media CPU and a stronger graphics core

^Got the Passmark stuff for A10-4600M 7660G graphics only though before it was deleted

A8-3870K GPU had 2 GB @ 1333 MHz
A10-4600M GPU had 1 GB @ 800 MHz
(both were 128 bit)

How to activate the Turbo Cores? I've recently bought a Toshiba S855D laptop and even when pushing the cores using prime95, the core speed never goes higher than 2.3ghz? Does anybody know how to activate the 3.2ghz speed on this APU?

I just realize that my Bus Speed never goes higher than 100mhz, my multipler goes to 23 that has no issues, but it's the Bus Speed that won't go to 200mhz, any ideas why?

thanks in advance
