post #311 of 991
based on my tests with my 290 and @BulletBait results with Rx 480 i think the difference between GCN1.4 and GCN 1.0 is very minimal in terms of Tesselation performance mad.gif

290 @1150-1675 Tesselation off = 15196
290 @1150-1675 Tesselation on = 14020

performance loss = 7.8%

RX 480 @1300-2250 Tesselation off = 14069
RX 480 @1300-2250 Tesselation on = 13162

Performance loss = 6.5%

i'm disappointed redface.gif

The tessellation levels used in Firestrike are actually sane. Even GCN 1.1 can handle it fairly well.

When you're looking at GameWorks and x64 tess...

Here you see an RX 480 matching a Fury X.

@BulletBait

would you run the FS @1300-2250 with these settings:

Best I could get with a moderate undervolt (-75mV) vs the aggressive undervolt (-125mV)

GPU Frequency: 3.5% (1310MHz)
GPU Voltages: 800/818/898/968/1018/1068/1075
Memory Frequency: 2250MHz
Memory Voltage: 1025
Fan Speed: 2750
Peak Temp: 65c
Power Level: +50%

GFX Score: 13282
No artifacts or crashes
http://www.3dmark.com/3dm/12847427

So, I was able to overclock +45MHz (3.5%) (plus the memory) w/ an ~9.5% undervolt on the GPU.

I'll get a little more aggressive on the voltage, might go back up to 1125, but I'll probably have to really ramp up the fan as well.

@lolerk52

Sure, I can do that.

can you try undervolt stock core and only clock memory up?
i wonder if that has any effect

290 @1150-1675 Tesselation off = 15247
290 @1150-1675 Tesselation Extremely on = 13311

performance loss = 12.7 %

RX 480 @1300-2250 Tesselation off = 14163
RX 480 @1300-2250 Tesselation Extremely on = 12858

Performance loss = 9.3 %

now thats more like it thumb.gif
