Toshiba Satellite X205-SLi3 Review

by Charles P. Jefferies

The X205 is Toshiba's top shelf gaming notebook, featuring single or dual Nvidia GeForce graphics cards and an expansive 17-inch widescreen display. The SLi3 unit tested here today has dual 8600M-GT video cards with 256MB of video memory each. The focus of this review the SLI technology and how much of a difference it makes.

Nvidia SLI &ndash; is it worth getting?

SLI technology harnesses the power of two graphics cards by linking them together. Before reading the benchmarking section of the article, those unfamiliar with Nvidia SLI Technology should see Nvidia's website for more information. According to Nvidia, up to a 2X increase in performance can be gained if the game being played supports SLI.

Is SLI technology worth the extra money? That is a good question because there are many games on the market that do not support SLI. I benchmarked a selection of the latest games to see how much of a difference SLI made.

Toshiba currently sells two versions of the X205; one series (reviewed earlier here) has a single 8700M-GT (30 &ndash; 40% more powerful than a single 8600M-GT), and the other X205-SLi3 being tested in this review has dual 8600M-GT cards. The fundamental problem with SLI is that if the game being played does not support SLI, then only one of the cards will be used, therefore giving the performance of only a single card. In a situation like that, having a single more powerful card would be an advantage because the performance would be higher. Given that the models carry similar pricetags, which X205, single graphics or dual graphis, is the better choice for today's gamer?

The Benchmarks

Benchmarking notes: All benchmarks were performed with the system plugged into AC power. I removed all bloatware on the system and minimized the number of running processes. I defragmented the hard disk drives and ran Windows Update. The video drivers used are the Nvidia 169.09 beta. All games tested were patched up to the latest version. Game benchmarking was done with FRAPS: http://www.fraps.com/

All game benchmarks were done during actual in-game play for 60 seconds. All FPS are rounded to the nearest tenth.

I used the following titles for testing:

• <!--[if !supportLists]--><!--[endif]-->Crysis
• <!--[endif]-->Call of Duty 4
• Half-Life 2: Lost Coast HDR Demo
• Quake Wars: Enemy Territory
• Unreal Tournament 3 Demo
• <!--[endif]-->Soldier of Fortune 3: Payback

Let the games begin!

Synthetic Benchmarks

3DMark06

	SLI Enabled	SLI Disabled
3DMark06 Score (Marks)	6,479	3,738
SM 2.0 Score (Marks)	2,966	1,553
SM 3.0 Score (Marks)	2,645	1,352
Return to Proxycon (FPS)	22.9	12.2
Firefly Forest (FPS)	26.5	13.7
Canyon Flight (SM 3.0)(FPS)	22.7	11.7
Deep Freeze (SM 3.0)(FPS)	30.2	15.3

Take a look at those numbers! The SLI score is about 73% higher than the non-SLI score, which is extremely impressive and while not the 2X performance increase Nvidia claims is possible, certainly impressive.

Below is a comparison of the Satellite X205-SLi3 performance in 3DMark06 to other gaming notebooks, including the Satellite X205 with the Nvidia 8700M-GT graphics card:

Crysis

Crysis is one of the newest first-person shooters on the market, and arguably the most demanding.

I used the following settings for benchmarking:

Main Settings (view large image)

Advanced Settings (view large image)

	SLI Enabled	SLI Disabled
Minimum FPS	15.0	10.0
Maximum FPS	36.0	23.0
Average FPS	24.1	14.9

When multi GPU support is enabled in Crysis, there is a substantial improvement in performance. The game goes from playable to unplayable when dual video cards are enabled. The average framerate when SLI is enabled increases by 61.7%.

Call of Duty 4

Call of Duty 4 is another recently-released first-person shooter with a high level of graphics detail and intense action. I used the following settings for benchmarking:

Call of Duty 4 Settings (view large image)

Note that I enabled dual video cards when SLI was enabled and disabled it for the single card benchmarking.

	SLI Enabled	SLI Disabled
Minimum FPS	27	26
Maximum FPS	94	78
Average FPS	53.5	42.7

There is a small improvement enabling SLI in Call of Duty 4, but the difference is not earth-shattering and not nearly the difference we should be seeing with SLI enabled. The average framerate only increased by 25.3%, well under the improvements we saw in 3DMark06 and Crysis. Fortunately, both the single- and dual-card setups were able to produce fluid framerates.

Half-Life 2: Lost Coast

This is an older game but has a good built-in benchmarking utility. This was the only game where I used built-in benchmarking tools provided with the game. I benchmarked with the following settings:

HL2 Settings (view large image)

Average FPS	SLI Enabled	SLI Disabled
0X AA	113.5	90.8
2X AA	111.0	79.5
4X AA	95.7	59.8

The SLI technology definitely went to work in this game, but the difference between one and two cards was not drastic. Without AA, the average FPS was only 25% higher, but when the AA was increased to 4X the FPS was 60% higher. Fortunately, both the single- and dual-card setups are able to produce more than playable framerates.

Quake Wars: Enemy Territory

Quake Wars is a recently-released first-person shooter with demanding graphics. It is primarily an online multiplayer game. I benchmarked with the following settings:

Quake Wars basic settings (view large image)

Quake Wars advanced settings (view large image)

	SLI Enabled	SLI Disabled
Minimum FPS	32.0	10.0
Maximum FPS	64.0	30.0
Average FPS	52.2	21.8

SLI makes an enormous difference in this game, more than doubling all the framerates. SLI is the difference between a playable and a non-playable gameplay experience at these settings. Most impressive!

Unreal Tournament 3 Demo

UT3 is the much-anticipated successor to UT2004. It is graphically demanding and takes advantage of a dual-core processor.

Benchmarking settings:

UT3 Basic Settings (view large image)

UT3 Advanced Settings (view large image)

	SLI Enabled	SLI Disabled
Minimum FPS	15.0	16.0
Maximum FPS	40.0	42.0
Average FPS	27.5	28.2

Unfortunately UT3 does not appear to gain any performance improvement from enabling SLI. I found that the game actually ran smoother with it disabled.

Soldier of Fortune 3: Payback

Soldier of Fortune 3 is a brand new game based on the Havok physics engine. The game looks similar to Call of Duty 4 and proved to be as demanding.

Benchmarking settings:

(view large image)

	SLI Enabled	SLI Disabled
Minimum FPS	11.0	14.0
Maximum FPS	32.0	39.0
Average FPS	20.0	23.2

SLI technology actually made Soldier of Fortune 3 run worse; I can safely make the assumption that this game does not support SLI technology. At the settings I benchmarked, the game is choppy.

All Games Overview

Below is a chart of the average FPS of all the games I tested added up. I used the average FPS for the 4X AA benchmark of Half-Life 2: Lost Coast.

	SLI Enabled	SLI Disabled	Performance Increase from SLI
Average FPS	273.0	190.6	43.2%

SLI Enabled Games Overview

Below is a chart of the FPS of only the games that showed a noticeable increase from enabling SLI.

	SLI Enabled	SLI Disabled	Performance Increase from SLI
Average FPS	225.5	139.2	62.0%

Using only the benchmarks from the SLI games, the increase is more substantial. SLI technology can do wonders for framerates if the game supports the technology.

Below are images showing the average temperature readings from the X205-SLi3 listed in degrees Fahrenheit:

Conclusion

Overall, the effectiveness of SLI technology is hit or miss. While it has plenty of potential as seen in Quake Wars: Enemy Territory and 3DMark06, the difference simply does not add up on the whole. One-third of the games I tested did not show any gain from enabling SLI and from those that did, only one showed a performance increase matching what Nvidia claims is possible (2X). Other games showed at best a 60 to 70% improvement (which is still impressive). The point is, do not expect an SLI gaming setup to literally double framerates.

As I stated at the beginning of the article, Toshiba sells two series of the X205 gaming notebook; one has a single 8700M-GT card and the other series, tested here, has dual 8600M-GTs. A single 8700M-GT is 30 to 40% faster than a single 8600M-GT on average. From looking at the all games average FPS table above, the 8700M-GT should be on par with the SLI setup for the games I tested from an overall FPS point of view. The performance of a single 8700M-GT would be considerably better than the 8600M-GT SLI setup in games that do not support SLI and therefore would provide a better gaming experience.

To those looking at the SLI notebooks, base your buying decision on the games you are playing. If only a few support SLI, then it would be best to get the non-SLI notebook with a stronger single video card. If the majority of your games support SLI, then get the SLI setup because it can do wonders for framerates.

 

Awesome comparison Chaz!

What happened to the first thread?

 

Thanks for the interesting read Chaz. I guess a single 8700M-GT card would generally be better for the thermal design as well, compared to dual 8600M-GTs.

 

I would have liked to have seen some direct comparisons between the x205 with single 8700m gt and the x205 with dual 8600m gt cards so to eliminate the need to use the word "should".

One thing people should also note is the overclockability of the 8600m cards. I have mine clocked faster than the 8700m GT cards and get over 8k in 3d mark 06.

 

A single one?

 

Superb article, as always, Chaz!

 

Techcally you could just go read the X205 review as many of the same games were tested.

Very helpful chaz! I loved this comparison, I personally don't think SLi is worth it because I play a lot of non supported games but if your a big-time mainstream FPS fan SLi is definitely for you. Aren't they are releasing a patch for UT3 that supports SLi?

 

Typo????????

 

Yeah, right... And i can overclock my 8700m GT faster than the 8800 Ultra for desktop and get over 2000000000 in 3dmark06....

 

Great review! The 3DMark06 scores are amazing for a $2500 Machine, coming close to the $4500 Alienware M9750, I would have thought 512 of 7950gtx and 2.33 would have dominated. Enemy Territory scores were very impressive for such a high resolution setting, 1680x1050. Is this the Shelby GT500 Mustang of the notebook world!

 

i want SLI setup now

 

Nice review! Very impressive indeed.

 

Thanks for all the compliments guys.

The reason I did not do any direct comparisons was because I didn't test all the games I did with the SLI one with the single GPU one back in August. Therefore, I would have only been able to compare a handful of games and would not have been able to make a fair conclusion.

 

I think this point should be stressed when reviewing this machine and more so when reviewing the sli1/sli3.

Troll!

 

I saw that notebook in Circuit City. That thing is HUGE!. Way too huge to be truly portable IMO. It's good as a portable desktop, but I'm not sure if something that big can even be called a notebook. it is nice though.

 

what i would really like to know is....what is the battery life? i'm guessing 4-5 hours.

 

I'm curious about the battery life and heat as well. Presumably battery life is better on the single card.

I have to say that I have the X205 '59 model and I'm completely happy with its gaming performance. I have no issue running NWN 2, Oblivion, Titan Quest and others at full native resolution with all the setting maxed out. If the dual setup is that much better than it is impressive indeed.

Correct me if I'm wrong, but these models don't include turbo memory do they?

 

Interesting! It is good to see that SLI does increase performance!

 

Since the SLI version is basically a single card with an additional gpu chip I dont think the power consumption is scalable like that of desktop cards. Reviews of the X205-SLI laptops show that HD-DVD playback limits battery life to roughly 70 minutes.

Getting the X205 necessitates an additional battery. This is a desktop replacement and performance is one of the worst "gaming" notebooks out there.

 

Yes and pigs just flew over my head. I think it would manage around 1:20 or so, I did not do an actual test. Based on how long I had the notebook unplugged, the battery life remaining seemed to tick by one percentage per minute.

It's not always much better - in games that do not support SLI the 8700M-GT will be significantly better. Personally, if I was buying an X205, I would get the 8700M-GT becuase I know most of the games I want to play do not support SLI.
Some X205s include Turbo Memory but this one does not. I believe the highest-end single GPU X205-S9359 does though.

 

Chaz re-do the UT3Demo benchmark, try it copying the UT3Demo.exe and then renaming the copy to Bioshock.exe, for some reason the UT3demo.exe is BROKEN using SLI. this will force the game to use a profile made for Bioshock that has a WORKING Unreal 3 based SLI profile.

 

X205 owners can share your experience of the battery life differences between the 9349/9359 vs SLi1/SLi3 ??
