Asus notebook GPUs (F8Sv/V2S/V1S)

I'm trying to find out more about these three video cards. Ok, so I know the specs read:

F8Sv: 8600M GT 256MB
V2S: 8600M GS 256MB
V1S: 8600M GT 512MB

I think I read Dreamer said that the V1S had a crippled 8600M, what does that mean (sorry I forgot which thread)?? Is it limited in bus width? Are they underclocked?

What are the specs on these (ie. core/memory/shader speed, bus(?) width, memory type, and where to find comparisons of how these cards perform)??

 

its not really crippled its ddr2 but im pretty sure the f8sv is also

 

Are they all DDR2? What other variants are there? Is it DDR2 or GDDR2? Reading Wikipedia didn't help From what I understand GDDR2 (like DDR1.5) < DDR2 < GDDR3 (DDR2.5) as they explained. But on their G8XM page it doesn't elabourate on the different variants between OEMs. GPUs are too confusing for me

Edit: Hey side question, does the F8Sv have a fingerprint reader? Asus website doesn't say it does but ExcaliburPC says it does. Anyone have it or know (link?) of other sellers??

 

i don really know that much...all i know is that gddr3>ddr2...srry

 

The only Asus computers that have the GDDR3 are the C90s, and the Asus G1s. That's it.

 

The V2s has a 64-bit 8600M-GS, don't know if it's underclocked or not, but it doesn't really matter as the memory bus width limits it's performance to the 8400M-GS range.

The V1s and F8sv both have normal DDR2 8600M-GT's, to the best of my knowledge.


And GDDR2 is an older tech that is not used in current mobile graphics cards. Right now it's GDDR3 and DDR2.

 

the whole G series, not just the G1

 

The v2s has a crippled graphics card.

 

That's what I meant to say haha... I guess I don't want to confuse anyone on the G2 having a different GPU.

 

How does one find out if the V2S 8600M GS is 64-bit? Isn't that false advertising?

According to wikipedia:

http://en.wikipedia.org/wiki/GeForce_8_Series#GeForce_8M_mobile_GPUs

8400M G is 64-bit, 8 steam processors
8400M GS is 64-bit, 16 steam processors
8400M GT is 128-bit, 16 steam processors
8600M GS is 128-bit, 16 steam processors, just faster clocks than 8400M GT
8600M GT is 128-bit, 32 steam processors

What do you mean - can you be more specific?

 

Probably underclocked is what he means...

 

But that's no problem because you can just adjust the clocks, correct?

PARTIALLY PWNT!

This asus has a radeon 2600 with DDR3 Vram. Not GDDR3 vram but it's not ddr2 vram. So my question is - diference between GDDR3 and DDR3 is?

 

According to Wikipedia, DDR3 > GDDR3 since GDDR3 is basically refined DDR2 ("...the power and heat dispersal requirements have been reduced somewhat, allowing for higher-speed memory modules, and simplified cooling systems.").

What I'm curious to know is if anyone can show benchmarks that prove there is a noticeable difference in the real world. Personally, I think that in synthetic benchmarks there might be a difference, and that it is true - if you are overclocking, you might get better results with different types, but at stock, the performance is negligible in real life.

 

First of all, the OP was asking about the 8600M cards with GDDR3 memory, HD2600 cards are a different matter. Secondly, the card you linked does not use DDR3 memory, it uses (most likely) GDDR3 memory.

DDR3 is not used in graphics cards currently. GDDR3 graphics cards are often mistakenly reported as having DDR3 memory, just as DDR2 graphics cards are often mistakenly reported as having GDDR2 memory. As for the difference between GDDR3 and DDR2, there's a very noticeable difference, at stock clocks and overclocked, in both real world games and synthetic benchmarks.

 

So by your message, you're implying GDDR2 isn't used anymore - correct? Are there any reviews with same notebook specs comparing same video card but one with DDR2 vs GDDR3? I'd be interested to see what power/temperature differences and overclocking potential.

Although if stock clocks are identical, why would performance be that different. For example, DDR2@1333C5 vs DDR3@1333C6 as close as possible in terms of timings, I don't think DDR3 was CAS5 but benefits of DDR3 was negated by slightly higher timings - aren't they roughly the same performance-wise? Wouldn't this be similar to the DDR2 vs GDDR3 thing? If GDDR3 and DDR2 clocked differently, what are their speeds that people have?!

 

GDDR2 is no longer used in graphics cards, at least in the mobile sector. Can't really talk about desktop cards, it's possible it still exists there.

And the main difference between GDDR3 and DDR2 are the clock speeds, DDR2 cards are normally stock clocked at 350-400, while GDDR3 cards are normally stock clocked at 600-800. For example, in the case of the 8600M-GT, the DDR2 version is spec'd at 400mhz and the GDDR3 version is spec'd at 700mhz.
