HP/Sony/Dell/etc. Vram DDR2 or GDDR3

I'm wondering if anyone knew if HP/Sony/Dell and all the major laptop companies used DDR2 or GDDR3 for their Video Cards?

I read that it makes a major difference whether the graphics card uses DDR2 or GDDR3 but most stores never tell you whether its DDR2 or GDDR3 they just give you "ATI Mobility RADEON® HD 4670 – 1GB

 

HP uses DDR2

 

Not all HP notebooks use DDR2, mine uses GDDR3, but most do. Lenovo, Dell, Sager, and Asus generally use GDDR3.

 

Asus and HP mostly use DDR2, but a lot of their recent models have been using GDDR3. Typically higher end models use GDDR3, while budget models use DDR2. If in doubt, Google the particular model and try to find GPU-Z screenshots from owners.

 

So does anyone know if the 512MB ATI Mobility Radeon HD 4570 from Dell on their Studio 15 line is GDDR3 or DDR2?

Is the ATI Mobility RADEON™ HD 4670 – 1GB on the Studio XPS 16 line GDDR3 or DDR2?

Also the Sony FW line does the ATI Mobility Radeon™ HD4650 graphics card with 1GB vRAM use GDDR3 or DDR2?

 

I know that both the Studio 1555 and Vaio FW line have GDDR3. I am pretty sure the Studio XPS uses it as well.

 

According to Catalyst Control Center my dv7 uses DDR3. DDR3 is slower than GDDR3 but at least twice as fast as DDR2.

 

Whoa whoa whoa...Graphics card have DDR3 too? I thought it was just DDR2 and GDDR3...

 

No, they can use DDR2, DDR3 and GDDR3. GDDR3 is basically memory that is optimized for GPUs, as it can be clocked higher and also has lower latency ( i think, not 100% on the latency part ).

 

So GDDR3 is faster than DDR3 which is faster than DDR2?

 

Yes it is.

 

Yep. Basically. GDDR5 is even faster. Although you only generally find that in high end desktop cards, like the 4870.

 

...There's a GDDR5 now? Makes my ATI Radeon HD3650 running on DDR2 feel like an old hag

 

^^^LOL nice way of putting that

 

For Sony it depends on the individual graphics cards in each notebook. DDR3 generally though.

 

It should actually be GDDR3. Not many companies use DDR3 ATM.

 

Really? I always see DDR3 instead of GDDR3. Is it just the seller being confused?

 

yeah, the m17x just got gddr5 4870s

 

So how fast is GDDR5 compared to everything else?

 

Usually that is the case. What does your GPU-Z say?

GDDR5 is about twice as fast as GDDR3.

 

Oh I see, as for what my GPU-Z says I'm actually talking about like on Xtopic the Nvidia GTX 260M says its DDR3 is that GDDR3 or just plain DDR3?

 

GPU-Z should be able to pick it out correctly, unfortunately.

 

So there's no way of knowing before you purchase it basically?

 

Not all laptops from one manufacturer will use just one type of VRAM. For what it's worth, the Dell Studio 1555's ATi 4570 (both the 256MB and 512MB versions) uses GDDR3 memory, as does the Inspiron 1545's 4330. The Studio 17's 3650, though, uses DDR2, while the Studio XPS 16's 4670 uses GDDR3, and I'm not sure about the 3670.

 

Cant wait to benchmark these puppies!

 

This is making me hate the fact that my 3650 is DDR2.

 

I second that!
