Hey, that's what they said, not me!

To be honest, I hope they get this new ZRAM going with 2MB of cache for every core!

On the AM2 platform cache amounts to nearly no performance boost. Maybe 2% difference.

But heres something..
Quote:
For example, AMD told us that 65 nm X2 processors consumes only 7.5 watt when idle, while a Core 2 Duo chip runs at about 14.3 watts.
This is also AMD's first 65nm chip, and 65W is the base power consumption, instead of the 89W of 90nm. As 65nm ramps up in production more so im sure 35W variants and below will become available.

Edit:
Quote:
5400+ (2.8 GHz), 5600+ (2.8 GHz), 5800+ (3.0 GHz) and 6000+ (3.0 GHz). The 5200+ and 5400+ will also be offered as 65 nm processors with a TDP of 76 watts.
Not quite as low as the 65W Core 2 Duo or the slower AMD chips, but Thats a helluva lot lower than the current FX-7#'s. If they could implement them in 4x4 enough it might actually be worth it for the money... But that probably wont happen for months, if at all.

There is no reason for AMD to put more L2 cache when it doesn't really affect performance, more cache is better when talking about the C2D, for K8 it doesn't make as much of a difference, so I don't see why some people are so hung up on the 512kb part o_O

Yorkfield will have 12mb of shared L2, K8L will have 4x512kb... and you know why K8L will only 512kb? because it doesn't "need" more (surprise!)

Saying that AMD doesn't need more than 512kb of cache is ignorant. That's like saying that since I have a 5ghz Conroe, I dont need more than 512MB of RAM. The CPU physically cannot hold items over 512kb in the cache of an AMD CPU. AMD really needs to quit cheaping out and make 2x1MB L2 standard on all of their chips. Who wants to spend their money on a crippled chip?

So basically, the new AMD chips still put out more heat than a Conroe. I seem to remember people making fun of Intel 65nm tech saying that AMD 90nm still runs cooler. It looks like the tables have turned.

I still don't understand why AMD is wasting their time with 4x4. Why would anybody go out and spend $1000 or more on a pair of CPUs when they can buy a QX6700 for $1100 which runs cooler, performs better, uses less power, and is quad core? It just doesn't make any sense to me... People act like 4x4 is innovative. How? Intel already has something that is much better. 2x Clovertown anyone? 8 cores.

EDIT

Adding cache to the AMDs doesnt effect performance? So what happened to them saying that the added 512KB of L2 added about 200mhz of performance? If what you guys are saying is true, the Venice and the San Diego should perform the same. Think about it.

The decreased latency provided by the IMC pretty much makes up for the lack of cache, no analogy is needed to show that. No analogy involving a 5GHz C2D and 512mb of RAM or even a 2.5GHz C2D with 1GB of RAM, just the IMC and decreased latency

http://www.phoronix.com/scan.php?pag...item=219&num=2

Quote:
In conclusion, for average users, we found that the San Diego offers an average of 3% higher return than its counter part, Venice, when running at the same clock speed.
=D

Quote:
The performance advantage is close to 10% in compiling LAME.
There is also that... =x

As 4x4 comment,you're partly right, it's a complete waste of money today but in 6-8 months it could be totally different scenario than what we're currently seeing

EDIT: There is definitely few more reasons as to why cache doesn't as large an effect on K8 as it does on the C2D but the IMC is a major one, so it's the only one I included

I did not say cache made no difference. Where do you get that?

On the AM2 platform ONLY does the cache offer menial perfromance boosts.

4x4 As of right now is only the beginning. All FX-line processors are going to be on 4x4. Like I said, if AMD puts out the 76W FX's since essentially the 76W Brisbane's are clocked at FX speeds I dont see a reason why they couldnt do that.

But ill quote again

Quote:
For example, AMD told us that 65 nm X2 processors consumes only 7.5 watt when idle, while a Core 2 Duo chip runs at about 14.3 watts.
Once AMD 65nm tech has matured a little im sure the Wattage will go down even further, and if theres any success the 35W variants will be more prevalent and cheaper, which beat the Core 2 Duo in power consumption.

And Clovertown is for servers, you'd have to be running a server style setup for that 8 cores. On the other hand 4x4 with K8L quad core will offer 8 cores for enthusiasts, as far as I know Intel doesnt have any plans for 8 cores for the consumer at least in 2007.

That's nice that they're finally getting these chips out but what's up with the half multis? Isn't that going to affect the speed of the memory? I think it's kinda lame to release speed grades with differences of only 100mhz.
