WinBook J4 Pentium 4 2.4GHz

Performance - Unreal Tournament 2003 (DM-Antalus)

We ran the WinBook J4 2.4GHz against a similarly configured 2.4GHz desktop system. The desktop system was outfitted with the ATI Radeon 7500 which is the chip the Mobility Radeon 7500 is based on.

Off the bat we can see that the WinBook J4 2.4GHz is missing something when it comes to 3D game performance. We mentioned earlier in this review that the Mobility Radeon 7500 running in the J4 was slower than other Mobility Radeon 7500 chips we have seen (260/143MHz vs 270/183MHz). This also put the Mobility Radeon 7500 in the J4 at a much lower clock speed than the desktop Radeon 7500 (260/143MHz Vs 290/230MHz). It is because of this low clock speed that the J4 gets handily beat by the desktop system; beat by 67%.

Cranking the resolution up doesn't help the J4 at all. As the game becomes more memory bandwidth intensive, the J4's performance falls 80% behind the desktop machine's. Let there be no question about it, the Mobility Radeon 7500 running at the full 270/183MHz would stand a much better chance against the desktop machine.

At 1024x768x32 the performance delta between the J4 and the desktop system increases to 82%. This should not reflect poorly upon the Mobility Radeon 7500 in general, as we proved it to be a worthy competitor here, but upon WinBook's implementation of the chip.

Topping the resolution which our SXGA+ LCD can display in the majority of games was 1280x1024x32. Look for the J4 to be 88% slower here.

Brining the detail level down increases speed and decreases the memory bandwidth requirements the game has. Running with medium details at 640x480x32 puts the J4 "only" 37% slower than the desktop board. Again, a full speed Mobility Radeon 7500 implementation would certainly help boost performance to almost desktop speeds.

800x600x32 with medium detail shows the J4 to be 40% slower than the desktop 2.4GHz system.

And 41% slower at 1024x768x32.

Finally, at 1280x1024x32, we see that the performance difference has grown to 42%. The performance delta between the J4 and the desktop system grows at increasing resolutions due to the decreased memory bandwidth and raw processing power that the J4's Mobility Radeon 7500 possesses.
