Bottlenecks (V2)- How Bad Could It Be?

bottlenecks

I’m sure many of you still remember the article I did late last year on bottleneck. Today, we have an updated version of this article, featuring the GTX280 and a host of other advancement.

What Is A Bottleneck?

No, it’s not part of a bottle. It’s a term to describe something being unable to cope with another, thus holding back performance. A choke-point if you would like another word for it.

The users who are concerned over this bottleneck matter are gamers. The thought of what a waste it would be to own a good graphic card yet having it under-perform due to lack of processing power.

Test Setup

Here’s the test setup used.

ProcessorIntel Coreâ„¢2 Duo E7200
Graphic CardASUS ENGTX280 TOP 1GB
RAM2x 2GB OCZ DDR2 PC2-8500 Reaper HPC Edition
MotherboardAlbatron PXP35
CoolerSunbeamtech Core-Contact Freezer Heatsink
Monitor20″ Dell Ultra-sharp Wide-screen LCD
Operating SystemWindows Vista Home Basic 32bit
Driver VersionGeForce 177.41

The Intel Core2Duo E7200 is a great processor to use for this setup, simply because of it can be easily overclocked and downclocked.

Configurations for Intel Coreâ„¢2 Duo E7200

RAM Speed266Mhz

The stock speed of the E7200 is 2.53 Ghz. To understand how processor affects gaming experience, I’ve overclocked it to 3.62Ghz and downclocked it to 1.6 Ghz as well.

At 3.62 Ghz overclocked speed, I would estimate the E7200 to be performing better than the Coreâ„¢2 Duo E8600 processor while the downclocked speed is similar to that of an Intel Pentium Dual-Core E2140 – E2180 range processor. So basically the processing power used in this article covers from anything that’s a notch or 2 faster than the E2140 and up to even more than the E8600 range (FYI – the E8600 is the most powerful dual-core processor available), which is more than enough to find out how processors work with the graphic card and how bad could the bottleneck be.

Test Results

F.E.A.R.

Graphic Detail : Maximum, 4x AA used.

Processor ModeResolutionAverage
Overclocked1680 x 1050144
Stock1680 x 1050120
Downclocked1680 x 105076

Thoughts : Looks like the game is playable with any processor used BUT notice how the framerates vary according to processor speed.

World In Conflict

Graphic Detail : Maximum, 4x AA used.

Processor ModeResolutionAverage
Overclocked1680 x 105043
Stock1680 x 105029
Downclocked1680 x 105020

Thoughts : Clearly a GTX280 paired with a low-end processor isn’t the way to go for this game. The E7200 even if paired with lesser graphic cards like GTX260 would probably outrun any GTX280 paired with low-end processor.

Company Of Heroes : Opposing Fronts

Graphic Detail : Maximum, 4x AA used.

Processor ModeResolutionAverage
Overclocked1680 x 105056.7
Stock1680 x 105055.6
Downclocked1680 x 105048.9

Thoughts : The processor boost only gained about additional 8 frames extra on average.

Lost Planet : Extreme Condition

Graphic Detail : Maximum, 4x AA used.

Processor ModeResolutionAverage (Snow)Average (Cave)
Overclocked1680 x 946 83.671.9
Stock1680 x 946 82.545.4
Downclocked1680 x 94653.2 31.5

Thoughts : The game seems to be playable on all range of available processing power as long as you have a good card but look at the degree of separation between the results.

The graphic card seems to be heavily under-powered. So does it make sense to spend RM 2,000 or so to acquire the cheapest processor and pair it with the highest range graphic card? I don’t think so, striking a balance would produce the same or better result. Plus a better processor would be great when it comes to processing data.

Just look at the test for Cave, notice how much framerates gained from the boost in processing power?

Crysis

Demo Version – Graphic Detail : Maximum, 4x AA used.

Processor ModeResolutionAverage
Overclocked1680 x 105023.91
Stock1680 x 105021.25
Downclocked1680 x 105019.47

Thoughts : Very minimal difference, looks like Crysis has greater dependency on the graphic card.

Conclusion

While using the best graphic card in the market with the lowest end processor seem to be fine when it comes to gaming, there’s no denying that by going this path means you’re really under-utilizing your gear. It’s like driving a Ferrari on KL’s Federal Highway during peak hour, so much fire-power and fuel guzzling but going no better than cars that cost less and drain less fuel.

Pair your graphic card and processor wisely, framerates are great with a high-end card but pair it with a low-end processor and their potential will not be harnessed.

Consider this – E2180 and GTX280 combo @ RM 1800 vs E7200 and GTX260 combo @ RM 1450, it’s not surprising that the RM 1450 combo would perform similar or better than the RM 1800 combo.

Now if only I have a GTX260. 🙂

  1. hi bro~~~may i know with my proc e2160…
    my problem is i don’t which graphic card should i go for…
    i scared tat if i choose 4850…it will bottleneck by my proc
    and as a result..the performance for 4850 will limit by the proc…mayb the performance for 4850 will same as 9800gt speed?
    if like this…i would rather go for 9800gt ? and 1 more thing…my mobo cant oc…n i only got budget to get a gc…can help me to solve this problem?thx

  2. and…am i worth to buy tat hd4850 to pair v my proc n play game?

  3. how to check the bottlenck?
    im using core 2 duo e8400, kingston high performance ram 2g 1033, 9800GT 1gb and odin 550w psu.

  4. Great article here. It’s surprising to know that a lot of people do not understand the meaning of bottlenecks. I’ve seen people pair up powerful graphic cards in SLI/crossfire but then have moderate CPU. What a waste! 😛

  5. @xian

    no u arent bottlenecked

  6. Author

    @xian – your spec looks fine. if you refer to the article, you can see that we can test our bottleneck by overclocking some parts. I should write an article on that. 🙂

    @dzimmo – yes, waste huh? I know some people who bought Quad-core (over RM 1k) and really expensive X48 board and run a single HD4850. damn!

  7. hi.
    i’m thinking of building a desktop. What will it be if i pair E7500 with normal stock with GW 4850 HD 512Mb GS? i would prefer performance + low temp card. Is the card I mentioned good enuf?

  8. Hi goldfries,
    Need advice, intend to pair my core 2 duo E4400(cant be OC coz mobo) with HD 5770, i dont mind got slightly bottleneck issue, but if huge i need to reconsider, based on your calculation, how worst it will be? I might be upgrading to core i 7 next year, but for now , wanted to play some nice game with better GPU. OR maybe i should get HD 4890 or GTX 260 instead? which will be wiser?
