CPU Benchmarks: Clock Speeds And Threading

Burnout Paradise: The Ultimate Box, Performance Analysis
By

Usually, it’s easy to benchmark CPU core and clock speed scaling, but with the 60 FPS limitation, it’s a little more complicated here. If we simply increase and decrease the number of CPU cores, we might see no difference at all if our clock speed is sufficient to keep the frame rate above 60 FPS. Thus, we’ll do the clock speed tests first to make sure we’re running lower than the vsync ceiling. We will disable CPU cores appropriately to make sure that if there are any differences, then they can be seen below the vsync limit.

We’ll run at a low resolution paired with the powerful Radeon HD 4850 video card to ensure that the graphics subsystem won’t interfere with the numbers.

Now that we have a method, let’s see how CPU clock speed affects Burnout Paradise:

We adjusted our clock speeds by lowering the CPU multiplier to keep everything else (such as memory speed) on an even keel. Note that the lowest multiplier available in the BIOS was 6x, which corresponded to the 1.8 GHz clock speed shown in the graph. Even at the dramatically-lowered clock speed, there seems to be little effect on game play. But it’s significant that the average speed is at least below the vsync limit of 60 FPS, which means we’re seeing a meaningful rate of maximum performance for that clock speed, and we are thus able to run our CPU core test.

The CPU core test shows us exactly what our recent How Many CPU Cores Do You Need? article suggests: this game utilizes up to three CPU cores efficiently and the biggest performance jump occurs between single and dual cores.

    How are you supposed to compare graphics quality using a GIF?!?

    Could you not have had multiple high quality JPEGs next to each other?

    EA = DRM title = No sale.

    The game isn't that great. I alway found it annoying having to search out races. If you've only got a few mins to spare it's nice to be able to jump it and get going.

    I always loved the Burnout series and always promised myself a copy when it appeared on the PC. I bought it the other day and I was immediately impressed with the gameplay and graphical prowess, esp considering my rig.

    Core 2 E6400 @ 2.1Ghz (One of the first versions)
    2GB Ram (I think one of the slowest clocked DDRII)
    and a
    Geforce 7900GS 512MB

    I thought I was going to have to drop the settings to the floor to play it, but they are quite comfortably on medium/medium high - admittedly on 1280 * 1024 res. But on a 17" monitor do I need a higher res?

    Still, for £30 you can't go far wrong. It has me coming back every night for a quick blast - with jaw dropping graphical moments every time.

    I tried the demo way before this article. Not my cup of tea. Too "arcady" for my liking. I didn't like the feel of the cars, camera angles and the damage....tbh I don't think that anything can beat GRID on the pc right now. Ok you cannot cruise around but it's all down to what you looking for.

    GRID is the ultimate arcade racer for the PC at the moment, if u want SIM then ur tlking GTR series.....

    Burnout is a different game when compared to GRID.
    GRID is pretty much a simulator, with some arcade elements.
    Burnout is about the thrill of speed, and the resulting crashes - not much else. A game for someone looking for pure fun!

    PT88Race Driver: Grid anyday!

    The chasis crunching gorgeousness of a head on inpact with a brick wall at full throttle easily passes the joy and frustration of driving the LeMans in Grid.

    Burnout wins in the Jump in and Go stakes. Just blasting round the city without furthering any set goals is fun in itself.

    The fact that the game runs well on lots of hardware can be taken 2 ways: either it is a good engine (as the article says) or conversly the level or detail is not as high as other PC games, coming as it does, from consoles originally. Although the Xbox360 & PS3 look good, we have to remember that they soon fall behind the PC in terms of graphics processing.
