Benchmarks or GTFO!

Yesterday when Apple unveiled the new iPad, the crew from Cupertino took some time to brag about its new A5X processor in comparison to NVIDIA’s Tegra 3. Apple certainly isn't widely known for offering up benchmarks on its own, so we'll likely have to wait until iPads land in the hands of reviewers and geeks around the web.
 
Apple used the iPad unveiling to boast that the A5X chip inside the new iPad is two times faster than A5, and four times more powerful in graphics performance than the Tegra 3.
 
 
NVIDIA isn't buying those claims without proof. The graphics company wants to know how Apple came by that number. Ken Brown, a spokesman for NVIDIA, stated, "[It was] certainly flattering " for Apple to compare its newest chip to their part.
 
Brown continued, “We don’t have the benchmark information. We have to understand what the application was that was used. Was it one or a variety of applications? What drivers were used? There are so many issues to get into with benchmark.”
 
Anyone that follows tech knows benchmarks are often handpicked to favor one particular brand over another when it comes to claims such as these. So it should be interesting to see if the new iPad’s performance lives up to the claims.

I've just seen you compared the iPhone 3GS to iPhone 4 (rather than 4 vs 4S) and said they benchmarked differently.

They have the same GPU - it benchmarks exactly the same.

The links do still serve a purpose in proving that benchmarks are at a constant resolution.

Glad you finally realized that.

Here's the phone benchmark on Anandtech. Since you seem hung up on only caring about individual component performance, try taking a look at how the phone performs.

http://www.anandtech.com/show/4243/dual-core-snapd...

GLBench-Egypt
iPhone3GS: 14.5
iPhone 4: 5.9

GLBench-Pro
iPhone3GS: 24.5
iPhone 4: 16.2

From Anandtech's own commentary:
quote:
Keep in mind that with GLBenchmark 2.0 we still cannot run at any resolution than native – in this case 800x480 (WVGA) – and the same applies for other devices in the suite, they're all at respective native resolutions.

The reason for the iPhone 4 lagging iPhone 3GS is display resolution, which unfortunately right now we can't test at anything other than native.<\quote>

The comment I made about comparisons of iPhone 4 to 4S still prove my point every bit as much. All of them, and benchmarks against other phone GPU's, are all at the same resolutions, not native resolutions.

I can't believe you posted that quote from Anandtech, which actually further proves my point.

'Unfortunately right now' they can't test on 'anything other than native'. That's an APOLOGY. Because, unlike you, Anand knows how proper benchmarks work.

Here's another quote from him:

quote:
they're all at respective native resolutions. GLBenchmark 3.0 will fix this somewhat with the ability to render into an off-screen buffer of arbitrary size.


Can you read that? Keyword - FIX. In all subsequent reviews where there has been an option to keep the resolution constant, he has.

As for why it's wrong, I will approach in my reply to your other failed argument on this topic.
