This video is funny:

It seems a lot of people(especially those owning Core i5 CPUs),were having a go at them for the review. Hence,they have redone it with a GTX670:

It is really funny!!

Good watch aswell really and it does highlight the fanboyism thats out there. Makes me want to keep my AM3 board and have 2PCs

That was the one I was meaning to link to!!

He really does that the piss out of them:

"Oh my gawd! Its bottlenecking....!"

"Hey guys(in dorky voice) lets run at 800X600 so we can...NO! NO! NO!"

"You can buy an AMD and save a couple of dollars but are going to spend a BILLION dollars over a three year period in electrical charges..BILLS!....the KW hours are going to EXPLODE OUT OF YOUR EARS!! NO! NO!"

Good watch, makes me not too sad I went to an AMD FX 8 core CPU.

Interesting they mentioned the hot fixes for the task scheduler. I did get them from MS for Win 7 but when I went to Win 8 I thought it was already fixed but they mentioned it still might need some fixes? Anyone know for sure?

Thanks for the link, I was thinking of getting the I5 but will go for the FX8350 now

Vishera based FX4130 is released:

Edit!!

AMD says that they have packaged a better cooler and the chip should be better for overclocking:

However,with a 125W TDP I would expect a better cooler??

[scaryjim]

Curious - presumably they're using FX4300 silicon that requires slightly higher voltages to hit 3.8GHz stably.

Ebuyer have stock, but at £87. The FX-4100 was only £81, so they've put a premium on the new part - then they've price-hacked the 4100 back to £75. Problem is, a Phenom II X4 965 is only £75, and is probably a better bet for many uses. Plus the FX4300 is only £96, with the same base clock, a higher turbo clock, and a lower TDP. There are better options both above and below the FX-4130. After all, a 5800k is only £94, and essentially provides the same CPU (although without L3 cache), plus a mid-range graphics card, in a lower overall TDP.

The 4130 will need some serious overclocking headroom to be worth more than a cursory glance...

AMD's CPU range is just too full in the < £100 range for this chip, really - they need to write off some Phenom II costs to clear inventory which will drive more people towards the FX quad-cores...

[CAT-THE-FIFTH]

The Vishera based FX4000 models also only have half the L3 cache of the Bulldozer based ones. The problem is the FX6300 can be had for around £100,which not only has the full 8MB of L3 cache but another two threads too. The FX6300 is better than the FX6200 and probably the FX4170 too I suspect.

The FX4130 would only make a good buy if it can overclock a lot on the provided stock cooler.

The thing is though,the provided FX6300 is meant to be an improvement over the existing cooler for 95W TDP AMD CPUs,as the fan is different,however,if they can provide a heatpipe cooler with the cheaper FX4130,I don't understand why they don't do so with the FX6300??

It would provide some overclocking headroom with the CPU and that would be a good point to advertise against the similarly priced Core i3 CPUs.

I have just finished a new build with 8350 well impressed so far not over clocked yet as i am deciding which cooler to go for but at stock speeds its very quick using my regular software i do a lot of video work and it does what it says on the tin saying of which the new packaging is great

It looks like the GT3 version of Haswell is delayed:

[scaryjim]

Bad for Intel - could end up launching alongside - or at least close to - Kaveri, which means GCN and possibly more cores (any rumours on the number of cores we can expect in Kaveri? Might be wishful thinking but I'd like to see a 7750-matching 512 )...

[CAT-THE-FIFTH]

It most likely uses the following core:

[mickyjim]

Hi Guys do any of you use AMD,s overdrive software for overclocking and would you recommend it ?

[scaryjim]

It most likely uses the following core:

384 GCN cores - I hope not - that'd show a real lack of ambitition. Even if they could clock it up to 1GHz on 28nm, it'd wouldn't be much of a step forward for their APU graphics.

I suspect you're right though, and I don't think GCN provides an awful lot of extra oomph over VLIW4 for graphics (although it's a much more compute oriented architecture, of course). Although maybe the thinking is that, while they're stuck on FM2, bandwidth limitations will be much more important than compute limitations as far as graphics capability goes, and adding a more powerful GPU would be a waste of silicon when you can't feed it enough memory bandwidth to operate effectively.

[watercooled]

Is Kaveri still meant to be on FM2? It would be nice if they could add some fast local memory on an interposer or something, and they should have experience with something similar considering the eDRAM, or whatever it's called now, used on the next Xbox?

As for GCN, from what I've read it seems it's more efficient than VLIW4, but not necessarily by a huge amount - it's essentially a RISC architecture and like you say, largely aimed at enabling more compute applications. VLIW, especially VLIW4, was already very efficient for graphics use.

[CAT-THE-FIFTH]

IIRC,a Chinese website compared the HD6930 and HD7870 at the same clockspeeds,and IIRC GCN was like 10% to 15% faster.

However,there is noise that since Kaveri is the first HSA enabled APU,there might be tighter integration between the CPU and IGP.
