Yet Another Graphics Benchmark

[Guest thenext1]

Just for the record.

I was documenting myself whether the new Galaxy S would be a big enough step up from my liquid, so I landed this page with some graphic benchmarks.

http://androidheadlines.com/2010/06/high-e...u-showdown.html

Unfortunately this page neglects our beloved phone, so I downloaded the linked Nenamark apk to my 2.1 Liquid (this app doesn't come up in market, wtf google filtering...).

The benchmark in itself is pretty short, about 20 seconds, but shows off a nice water reflection.

The most surprising, is that the Liquid actually comes on top all of its resolution-wise competitors with 14,0 FPS and a sizable edge over the Droid which is the 2nd one.

Even faster than the 2.2'd Nexus One.

Why is this?

cause liquid rulez,fellow,remember this))

I scored 15.9fps on stream dump, highest that i have seen on any device, there's a possibility that MAYBE the acer liquid stream open gl es 2.0 driver are optimized or something, but again that's just me crazy talking...

I ran neo core on my Liquid and a friends Nexus one

I got 27.4fps and the nexus one got 26.7

ran it a few more times, got similar results, Liquid beating Nexus one, despite the liquid being underclocked and having less ram

Dont waist your time running an open gl es 1.1 benchmark on your liquid or any other qsd8xxx device for that matter, it will never stress the gpu like an open gl es 2.0 benchmark would.

RAM and CPU have NOTHING to do with 3D!

I've 15.9 too, but on LCr 1.6, so there isn't better drivers on Acer Stream Dump

RAM and CPU DO affect 3D

Put a Underclocked Celeron processor and 3 ATI 5870s together and put it against a Core i7 with 3 ATI 5870, there is a huge difference

The Snapdragon processor has an Adreno GPU, so the Liquid, Nexus one, Evo, Incredible and the Desire have the same CPU and GPU

Acer liquid's processor is underclocked, this may or may not include underclocking the GPU, but I think its likely

Also how much RAM is used as a frame buffer / used for VRAM?

It might be different with the snapdragon, but the old G1 used RAM for its VRAM, and users could gain 8MB of RAM by installing a hack to reduce the RAM used for Video, in exchange for next to no 3d performance

Since the Snapdragon and the MSM7200 are both made by Qualcomm, both of them might use the same tactic for using RAM

Even the Xbox360 shares RAM between the system and video

Underclocked CPU might also mean a slower bus, which means slower access to RAM which will affect 3D performance if some of the RAM is used as VRAM

We should compare with a reference rendering.

Maybe the graphics driver in Acer's 2.1 has bugs and doesn't render some GPU-heavy polygons or effects.

Recall that 1.6 driver was bugged and problematic with most 3d games.

Anyway, it's sad that magazines completely snob our Liquids for comparison testing... No Liquid in this GPU test, no Liquid in the touch panel precision test... I think the Liquid has something to say in all of these tests!

Using Eclair's (or Stream's) drivers on Froyo (Donut kernel), gives "poor results" (ie around 12FPS), so it's definitely not because of bad drivers.

The only explanation I can see, is that the GPU is actually OVERclocked on Acer's Eclair compared to Donut or other QSD phones.

(The GPU clock is handled by the radio ROM (could be done by the kernel, but that's REALLY unlikely))

If someone could test nenamark on Froyo on an Eclair radio ROM, that would help understanding this stuff ;)

I pushed froyo on an eclair rom, nenamark1 FC dont know why, btw thanks for your help phh =]

[Guest fischschneehase]

an newest bin 1.10015 i score with neocore 28 fps!!!
