Intel GMA 4500m or X4500MHD

I am looking at two laptops Toshiba T135 and ASUS UL20 (both are in the high $500 range). From what i can gather T135 has Intel GMA 4500M and UL20 has Intel GMA X4500MHD chipset.
Is my information correct regarding chipsets?
If so, does the Toshiba have the GL40 or GS40 version and does the ASUS have Gm45 or GS45?
The reason why I ask is all the reviews I have seen say Toshiba can play 720p and 1080p videos without bogging down the CPU and it does have HDMI out, yet all the info about Intel GMA 4500M I saw states that it cannot decode HD video.

 

As far as I know, all laptops that have the Intel GMA 4500 have HD decoding - that is, they are all the GMA 4500MHD. The 4500M only exists in desktops, I believe. Therefore, both those laptops are capable of playing HD content smoothly.

 

GL40 is the budget mainboard for Celerons and Pentiums.

GS40 is the CULV mainboard used by ultrathin notebooks.

GM45 is the mainboard used by the more expensive Intel prosessors.

 

It's all misnomers - the only 4-series GMA in notebooks is the 4500MHD, which is available on the GL40, GS40, and GM45 chipsets (albeit at different clock speeds).
The X4500 and X4500HD are desktop only.

 

Sorry, but forgot to mention that the Intel GL40 budget mainboard lacks HDMI output, at least on the one i own.
But for DXVA HD playback on Intel hardware, click on the link in my signature. xD
1080p trailer of Avatar plays flawlessly, but the low res 1366x768 makes the screenshots a little undetailed.

Recommend Splash Media Player if your looking for a easy to use and free solution for 1080p playback on Intel hardware or K-lite codec pack with MPC - Home Cinema if your looking for a more advanced solution that covers nearly every codec known to man.

Good Luck!
(And a happy new year)

 

the compute with the GM45 chipset will most likely have HDMI output...

 

see this is where I am lost. In a way everyone is correct based on the info available on the net and yet its contradicting.
As TehSuigi & MidnightSun said all 4500 GMAs in laptops are HD, which could be very well true since every laptop with 4500 review is saw was able to play 720p and 1080p (some did have issues with 1080p flash but from what i can see its a driver issues)
And DEagleson is correct based on the intel site:
GM45 ( http://www.intel.com/products/notebook/chipsets/gm45/gm45-overview.htm) and GS45 ( http://www.intel.com/Products/Notebook/Chipsets/GS45/GS45-overview.htm) are chipsets for laptop based Intel® Core™2 Duo processor and can play HD
While GL40 ( http://www.intel.com/Products/Notebook/Chipsets/GL40/GL40-overview.htm) and GS40 ( http://www.intel.com/Products/Notebook/Chipsets/GS40/GS40-overview.htm) are chipsets for laptop based Intel® Celeron® processor and it does not state anywhere wether or not they play 720p or 1080p so I assume they do not.
Since CPU in ASUS UL20 is core 2 duo then it makes sense that it has 4500hd (even though it does not have HDMI out). While for Toshiba T135 specs say gma 4500 (without HD), it also make sense cuz SU4100 is dual core but not core 2 duo and yet Toshiba has HDMI out and people on the net claim the laptop can play 720p and 1080p files.

 

Damn you Intel for making so many versions of the same thing. xD

But since the Toshiba have a HDMI output i would take that, since that is what your looking for.
That GL40 notebook my brother had could not decode 1080p, but after downloading the latest Windows 7 Intel GMA driver it got identified as a GM45 in GPU-Z and Splash Media Player 1.0.5 could enable hardware accelleration on H.264.

 

They both have the same GPU and will perform the same on HD video= Very good.

 

According to notebookcheck.net, there is a difference.
"Compared to the GMA 4500M HD, the 4500M features a slower core clock (400 MHz versus 533MHz) and is thus a bit slower in games.

The chip itself is capable of supporting the CPU to decode HD videos, but because of the slower clock rate, the 4500M has troubles decoding 1080p videos fluently and therefore has no full Blu-Ray logo support."

Marketing bonanza. Both will play 1080p fine.

Make sure to get a dual core though, or you won't be playing Flash and WMV HD.

 

Are you guys REALLY sure about that?

If the 4500MHD is the one and only Intel GMA in 4-series GMAs why is Windows telling me something else?
My 5635Z-432G16N which is supposed to have a GMA4500MHD inside shows this:

GMA4500M is @ 400 MHz and GMA4500MHD @ 533 MHz, right?

So, GL40 chipset + GM45 chipsets's GPU (GMA4500MHD) clocked @ 475 Mhz =


PS: This guy is very confident that both, GMA4500M and GMA4500MHD, exist:

By the way, GPU-Z is crap at identifying Intel GPUs. They STILL base G45/GM45 chipset IGPs clocks as being 475MHz, which was true when the hardware was Beta. It does not have 10 ROPs and TMUs either. They are utterly and completely wrong.

GL40=GMA 4500M
GM45/GS45=GMA 4500MHD

Clocks are...

GL40=400MHz
GS45=320MHz but supports HD Turbo that can clock up to 533MHz only with HD Video
GS45 with 1066MHz FSB CPUs=533MHz
GM45=533MHz

GL40 supports MOST of the HD video acceleration. The difference will be pretty minor I think. They do not cripple the "value" chipsets as much as they do on desktops. Yes, GM45 will be better.

 

I did not say they are the same, I said both will play 1080p video fine.

Am I sure? no. But please show me if I'm wrong.

That's what I thought too.

 

the X4500HD is called G45, theres no GM/L/S. and it runs at a higher clock of 800MHz (if i remember correctly)

GMA4500MHD has a slower clock, being mobile

 

Whatever the case , u can easily Overclock both GPUs to GM45 speed using GMA booster...

 

I believe the GMABooster only works with 915G and 945G.

 

yeah they claim to be "in the works" pending hardware donations for testing.

 

i recently bought a windows 7 notebook advertised as having an Intel GMA 4500m HD. The tax ionvoice states Intel GMA 4500, the computer says i have an Intel GMA 4500m. Is there anyway of finding out exactly which one i have?
