News Intel's Latest GPU Drivers Are Half the Size They Used to Be

[Admin]

Intel's Arc drivers were relatively huge at launch, but in the past two months they've shrunk to less than half their former . Impressive!

Intel's Latest GPU Drivers Are Half the Size They Used to Be : Read more

Why the extra 500+ MB? We're not sure, but there were a lot of bug fixes and other factors that likely played a role. Later in October, the size dropped by about 170 MB.

I'm not sure about earlier driver versions, but wasn't the "unexpected" increase in the driver’s size a result of INTEL combining both the Arc Control software and Iris GPU drivers under ONE package as of late ? Which has lead Intel to include compression algorithms in the latest release ?

But like you mentioned it seems a bit odd that compression algorithms are the reason behind the shrink in file size. Btw, the drivers were also supporting both the desktop and mobile graphics side.

I'm not sure about earlier driver versions, but wasn't the "unexpected" increase in the driver’s size a result of INTEL combining both the Arc Control software and Iris GPU drivers under ONE package as of late ? Which has lead Intel to include compression algorithms in the latest release ?

But like you mentioned it seems a bit odd that compression algorithms are the reason behind the shrink in file size. Btw, the drivers were also supporting both the desktop and mobile graphics side.

I actually updated that paragraph, after some feedback from Intel. I forgot all about the Arc Control being a separate piece of software. The new version:

"There are a few things worth pointing out, like the jump in size when Intel went from just supporting the A380 (and various existing integrated graphics solutions) to the official Arc launch drivers. Why the extra 500+ MB? Part of it was merging the Arc Control Center into the main driver download, and there were bug fixes and other factors that likely played a role. Later in October, the size dropped by about 170 MB."

I don't think we'll get any statement as to any other fundamental changes. However, the file format has definitely changed. Version 4125 for example, if I open in 7-zip, I can't really find the file structure. With 4255, I can see what looks to be a normal layout. Also, 4255 extracts (via 7-zip) to 237 files, 11 folders, and a size of 1.86GB. So it has almost a 3:1 compression ratio. I really do wish I could see the same with earlier drivers. Well, I suppose I could try starting the install, see if they get extracted to a folder...

Oh! That's fun. So 4125 extracts some stuff to the user\appdata\local\temp location, but then the main stuff goes into C:\ProgramData\Package Cache\2D0756B5DBFB74417E9B06D2DDE3FBCD47A59DE5 (probably a random folder name). But all the file structure looks about the same. So, let me see... 235 files, 11 folders, and a size of 1.30GB. Wow, I'm not sure what to think about that. The old installer seemed to have a smaller installer?

Ah! I figured it out. The older installer would unpack with a bunch of compressed files (*.dl_ for example). So if you inflate all of those it probably gets to be about the same size. The only two "new" files I can see are:
03/22/2023 11:13 AM 30,599,648 media_bin_32.dll
03/22/2023 11:14 AM 30,789,760 media_bin_64.dll

But 4255 has this as well:
03/22/2023 11:09 AM 18,034,160 igvkMedia32.dll
03/22/2023 11:10 AM 19,019,736 igvkMedia64.dll

4125 meanwhile has this:
02/14/2023 02:21 PM 26,489,385 igvkMedia32.dl_
02/14/2023 02:21 PM 27,003,231 igvkMedia64.dl_

Considering the 4125 dl_ files are still compressed, it looks like there's just some stuff pulled out into a separate DLL now. But let's summarize. Here's the 4125 contents, expanded:

C:\ProgramData\Package Cache\2D0756B5DBFB74417E9B06D2DDE3FBCD47A59DE5>dir /a/s

So after expansion, the new drivers are about 400MB smaller still. Interesting, not sure if that's all that changed, but there are a lot of smaller DLLs in the updated drivers.

I actually updated that paragraph, after some feedback from Intel. I forgot all about the Arc Control being a separate piece of software. The new version:

"There are a few things worth pointing out, like the jump in size when Intel went from just supporting the A380 (and various existing integrated graphics solutions) to the official Arc launch drivers. Why the extra 500+ MB? Part of it was merging the Arc Control Center into the main driver download, and there were bug fixes and other factors that likely played a role. Later in October, the size dropped by about 170 MB."

I don't think we'll get any statement as to any other fundamental changes. However, the file format has definitely changed. Version 4125 for example, if I open in 7-zip, I can't really find the file structure. With 4255, I can see what looks to be a normal layout. Also, 4255 extracts (via 7-zip) to 237 files, 11 folders, and a size of 1.86GB. So it has almost a 3:1 compression ratio. I really do wish I could see the same with earlier drivers. Well, I suppose I could try starting the install, see if they get extracted to a folder...

Oh! That's fun. So 4125 extracts some stuff to the user\appdata\local\temp location, but then the main stuff goes into C:\ProgramData\Package Cache\2D0756B5DBFB74417E9B06D2DDE3FBCD47A59DE5 (probably a random folder name). But all the file structure looks about the same. So, let me see... 235 files, 11 folders, and a size of 1.30GB. Wow, I'm not sure what to think about that. The old installer seemed to have a smaller installer?

Ah! I figured it out. The older installer would unpack with a bunch of compressed files (*.dl_ for example). So if you inflate all of those it probably gets to be about the same size. The only two "new" files I can see are:
03/22/2023 11:13 AM 30,599,648 media_bin_32.dll
03/22/2023 11:14 AM 30,789,760 media_bin_64.dll

But 4255 has this as well:
03/22/2023 11:09 AM 18,034,160 igvkMedia32.dll
03/22/2023 11:10 AM 19,019,736 igvkMedia64.dll

4125 meanwhile has this:
02/14/2023 02:21 PM 26,489,385 igvkMedia32.dl_
02/14/2023 02:21 PM 27,003,231 igvkMedia64.dl_

Nice observation and analysis, with breakdown on the file contents. 👍

It's a bit confusing though, especially the final extraction size of the files in both the versions. But is there is a difference between igvkMedia32.dll and igvkMedia32.dl_ files (including the 64-bit version) ?

I would assume the *.dl_ format is just more "compressed" ? Also, I presume the latest 4255 driver version still contains the Arc Control Center software included as well, and Intel has not completely nuked it out as well ?

Since the code does say this , IntelArcControl.exe , 2 File(s) 284,744,616 bytes . So Intel did really used a smarter compression algorithm it seems.

The previous 4125 version has this, IntelArcControl.exe 2 File(s) 471,924,616 bytes. So I would assume they made some changes to the ARC control Software as well ?

Here's a better breakdown, in image format. Red is for files that got larger, green is for files (and folders) that got smaller. I've updated the end of the article to link to this post, and provided a bit of an analysis on the compression algorithm upgrade.

Lots of stuff didn't change, but overall the new drivers eliminated at least 450M of uncompressed data. From what I can tell, the main difference seems to be that the new drivers put a bunch of stuff into media_bin_32.dll and media_bin_64.dll, whereas that same information was previously replicated in eight different files. The two new files are about ~30MB each, but the eight other DLLs are each about ~38MB smaller. So, fundamentally, if I'm right, by removing that duplicated data Intel shaved off around 300MB of file size and replaced it with 60MB. That's a 240MB difference. And then, as you noticed, there's "Intel-Driver-and-Support-Assistant-Installer.exe" which now appears to be a tool to download the installer (it's ~44MB) where before it was the full installer (~240MB). Those two changes taken together account for most of the ~460MB file size reduction.

Excellent ! Now I get a much clearer picture. Nice finding though, and I appreciate the time and effort you put to analyze the data. Yes, it appears that current 60MB data (media_bin_32.dll and media_bin_64.dll) was previously 300+MB in size, so that does make a difference.

Also, I think INTEL can also provide 2 different drivers of the same version to download. I mean, based on the Intel-Driver-and-Support-Assistant-Installer.exe file, they can use this as a full installer, similar to what we get on an offline download package, where the user does not have to install any other extra files from the internet, since the package contains ALL the files.

Whereas, the other package can include just the TOOL itself for those who want an online installer of some sort. Both would be optional depending on user's needs. Of course, this idea sounds pretty silly and it's pointless to implement 2 files for the same version, but I have noticed some software packages come in 2 different flavors.

Like an "offline" and "online" installer exe file, which differs in size, as it is named on some software download sites. Just saying.
