New 7900 part numbers - Page 10

Good news for those of you that have a 9400. I found a thread about someone that owned 9400 for a couple of months and successfully got Dell to take back their laptop with full refund and free shipping back to them.

So those of you with a 9400/X1400 or integrated and want a 9400/7900 or M1710 you have a chance still to return you laptops.

Hey all,

Been reading the forum for a while, and decided to chirp in.

I see two listings for bare 7900GTX 512MB Go's over on eBay. Can't vouch for the seller or anything... but it must be a sign that these are coming into the pipeline (search 7900, under Laptop Parts/Video & Sound for Laptop).

Anyone brave enough? (I'm not )

This is indeed .

I dont recommend everyone who is not satisified with there choice of GPU go back and try to get Dell to give you a new or upgraded laptop. This practice will only serve to raise prices and lower the ability for those with a real replacement need to get one. Just my .02 Cents.

Those are for Laptops, but not Dell version. SLI ONLY!! Sorry, I was almost ready to bid.

Hey aibal,

I don't know enough to agree or disagree... non-Dell, or sli?

But there's some questioning of the eBay selling going on already... I think I'll ask the guy myself

Well you might be right. I asked the seller to post an actual picture of the card. The one he has pictured will NEVER fit into any Dell notebook. Just because he says it will might not mean that he knows what he's talking about. Hopefully he will respond to my request. Also 0 feedback? That makes me a little uncertain as to the legitimacy of his auction(s).

This thread proves you have no idea what you are talking about.

The Merom is a fricking BEAST!!!!!!!!!!!!!!!!!!!!!!!!!

He said games and he's right. Most games are GPU limited so the Merom won't make any difference at all at high resolutions.

So I can run a P3 and a 7800GTX and a Yonah with a 7800 GTX and there will be no difference whatever.

The 3DMark scores don't lie.

that is a lame comparision and obviously not what was meant. Obviously you can take anything to the extreme. However here they are refering like to p4s running at same speeds. Then likely no real difference.

My example is I have a desktop with a amd64 single core and a 7900gt. Going dual core gave no advanatage in gaming. I know as I purchased tested and returned the dual core when my 3dmark score was worse and had no gain in gaming exerience. Now if you want to do more than one thing while gaming then yeah the dual core would benefit. However most dont do that so the dual core is not needed.

Fair enough but the argument was in the other guy saying there was no difference between the Yonah and the Merom. The benchmarks put that to rest.

Dude!!! I work at Intel. You guys want 3dmark comparisons? I can do it tomorrow. Now from Conroe to Kentsfields there's a big!!! Difference. 3dmark06 will jump 1000 points from 6000 to 7000 using a x1900xtx just by dropping in the kentsfield. CPU score in 3dmark06 is 2500 on a 2.93 conroe and a 2.67 kentsfield will get 4000. No difference between the two using 3dmark05 because 05 can't utilize the other two cores. Actually the conroe gets about a 400 points difference because of the increased clock speeds.

You know the only diffence between the yonah/merom is 2mb cache vs. 4mb cache. No extra cores, no faster fbs or clock frequencies. It's like is there a difference between 2gb of ram vs. 4gb of ram in gaming in XP? Most likely not. But I think there will be a difference between the two when Windows Vista comes out.

Yes there will be because of the clock rates. Merom/Yonah does not have any different clock rates. Games right now don't know how to handle 4mbs of cache currently only 2mb. But there will be a difference about a 2% difference.

I said no difference in games but in video editing a big difference. Read before you post

More inaccurate information thats why I don't buy your story. You keep posting inaccurate information and passing it off as something factual.

"The big difference between Yonah and Merom is one of performance and power consumption. Yonah represents a re-design of the older Pentium M processor that worked so well in older notebooks while Merom (and the rest of the Intel Core Microarchitecture processor family) represents an all-new architecture. 64-bit and power consumption are the biggest new factors that Merom brings. From my reading on the subject (see AnandTech and Wikipedia) the following are the main benefits:

1. 64-Bit processing to support more than 4GB RAM (great for desktops/servers, perhaps of limited use in a notebook)

Guess 64-Bit is not a big difference lol

2. Lower power consumption by doing things like combining 2 instructions into 1 and therefore saving a clock cycle, and scaling power usage according to processor load

3. Support for faster Front Sided Bus to access main memory (800MHz with Merom; 1.33GHz for the Server/Desktop versions)

Hardware supported virtualisation had been proposed as another selling point for these processors but, as we know from the Parallel Workstation product, this is already supported in Yonah.

While the power consumption required by Merom is lower than Yonah, don't expect to be seeing much in the way of increased battery performance. Most likely the laptop will be set to use its more efficient processing to do more with the same power and therefore outperform an equivalently clocked Yonah by about 20% or more (Quake 4 demonstration showed a 25% performance increase over Yonah in the AnandTech article)."

This would also explain why the 3DMark scores are better but of course there is only a cache difference lol.

hate to break it to you I don't believe you at all. Quad cores are basically NDA. Please provide proof. Oh wait you can't! LOL

Actually... most games other than F.E.A.R. are CPU limited. Reach the benchmark results of your favorite review site (any of them) more carefully. System Ram and CPU are important to gaming - most games that have been out 2-3 months before a new video card will barely stress that video card, and become CPU limited, especially on the mobile platforms - and Merom/Yonah make up for this in big ways in gaming.

Here you go I'll let you guys guess what pic belongs to what proc. Remember none of these are released, so the names are generic.

Nothing is OC'd. Not the GPU or the CPU. But when I do OC, it makes my mouth water. Nice EYE candy. Too bad I can't take these home for my home system. Imagine 19000 3dmark05 & 13000 06 points, all on stock heatsinks, no water cooling. I just think 40 3dmark06 points is not worth waiting 6 months for. Intel may improve the specs a little but not by much till release, but they better hurry cause launch date is just around the corner.

I don't think 64-bit is a big difference. I certainly do not care right now. How many 64-bit games are out right now? Can you name 10 of them? I may care in a couple of years if game developers code their apps in EM64T but I don't think games are gonna go down that road. Not within 2 years. I also can careless for power consumption. I'll probably only save a buck on my electric bill and 10 minutes in battery life.

As for the FSB, I do not know what Intel has plans for it when it is released but I can tell you the one in my hands right now is 667. In fact we got 30 different variations of the CPU and all but 1 is 667. So maybe Intel may decide to release a EE version of it. But I can tell it's gonna be Extra Expensive.

This is my last post in here. Too all the people trying to put a 7900GTX in their 9300/M170 Good luck!!!

Btw... to those that don't think Merom will give a performance boost, think again.

As I've discussed with others here before - 64bit isn't where the boost comes from. The performance gain of about 20% across the board that you'll see from Merom over Yonah is due to the number of instruction sets supported, and the number of instructions that can be executed per clock cycle.

Yonah was a big jump over Dothan because it added the SSE2 SSE3 support that would lag behind in games compared to P4's in some games. Yonah also only handles 3 instruction sets per clock cycle. This means it can process (2) 32bit base instructions and (1) MMX/SSE/SSE2/SSE3 instruction per clock cycle.

Now here comes Merom, which adds EM64T 64bit instruction support. And on top of that, Merom can handle 4 instructions per clock cycle. This can be either (3) 32bit base instructions & (1) MMX/SSE/SSE2/SSE3/EM64T instructions... or (2) 32bit base instructions & (2) MMX/SSE/SSE2/SSE3/EM64T instructions per clock. This flexibility in Merom is how it will produce 20% increases in games and business applications over Yonah.

So please, do your homework please before bashing each other. 64bit won't make the difference... the number of support instructions, and the way Merom implements them is where the difference comes in.
