Today a test and review on the new AMD ATI Radeon HD 4870 1024MB. Obviously ATI is releasing a 1GB model to compete with the new Core 216 version of that GeForce GTX 260. The 4870 series really diggs... More...
Thank you for this test. It looks like more RAM will be useful in near future. But I've got 2 questions: 1. It looks like low-power mode isn't working well. Was there any explanation from the manufacturer? 2. Is there any possibility to re-test 4870 512 and 4870X2? It looks like there are driver changes both for overall performance and utilization of greater amount of RAM.
Should be "competition". I keep forgetting; does Guru3D have editers? only messing. Keep up the (normally) great work.
haha. Its true like, the editor that goes through these articles fails to correct any mistakes what so ever it seems. I've kept my mouth shut until now
Because GRID was removed from the benchmarks due to being too time intensive iirc., just forgot to remove the title. tbh the extra memory on the card didn't make as much difference as I was expecting, thought it would do more at high resolutions.
This is the single GPU of choice. If I didn't get my GX2 for under £150 I would have 2 of these running.
I think if you had crossfire disabled and only one card being used, it would be using the whole 1 gig. But I'm not 100% on that.
If you use the 1GB as the master and 512MB as slave it will use 512MB max. When you disable CF you will have the single GPU with 1GB back.
The truth is, the 512 mb only costs about $30 extra here in Canada, so it may be worth getting the extra RAM. Guru3d's review is pretty good, but I think what one thing that might have been interesting is looking at the minimum frame rate. You'll likely find that the 1024 Mb makes a difference well worth the 512 Mb. Advantages: - Faster frame rates - More "future proof" Disadvantages: - Costs about $30 more (so maybe 15-20 euros more) - Extra RAM may not be as overclockable (need to find verify this one)
