s800 Posted December 13, 2008 Share Posted December 13, 2008 I've been experimenting with various gfx cards lately, and noticed something strange. My 7800GT/256 Asus card gets the following Xbench results: Quartz Graphics Test 229.17 Line 201.22 13.40 Klines/sec [50% alpha] Rectangle 287.65 85.88 Krects/sec [50% alpha] Circle 231.24 18.85 Kcircles/sec [50% alpha] Bezier 212.78 5.37 Kbeziers/sec [50% alpha] Text 230.04 14.39 Kchars/sec OpenGL Graphics Test 237.97 Spinning Squares 237.97 301.88 frames/sec User Interface Test 407.81 Elements 407.81 1.87 Krefresh/sec Disk Test 72.89 I swapped in a 9800GTX/512 EVGA and got: Quartz Graphics Test 217.44 Line 195.42 13.01 Klines/sec [50% alpha] Rectangle 267.69 79.92 Krects/sec [50% alpha] Circle 214.91 17.52 Kcircles/sec [50% alpha] Bezier 204.62 5.16 Kbeziers/sec [50% alpha] Text 217.32 13.59 Kchars/sec OpenGL Graphics Test 200.41 Spinning Squares 200.41 254.24 frames/sec User Interface Test 336.62 Elements 336.62 1.54 Krefresh/sec --- Cliff notes: 7800GT is 10% faster on 10.5.5 w/ NVinject 0.2.1 than a 9800GTX. Any thoughts? I should also say that I switched from the 256 to 512 Nvinject to test the two cards, and they were correctly identified.

I'm sure its a fine driver but I dont trust anything except EFI strings...try that Link to comment https://www.insanelymac.com/forum/topic/140810-7800gt-9800gtx-loss-in-performance/#findComment-997541 Share on other sites More sharing options...
s800 Posted December 16, 2008 Author Share Posted December 16, 2008 Okay, switched to gfx strings (thanks aqua!). Still the same speed. Here's my info: Chipset Model: NVIDIA GeForce 9800 GTX DDL Type: Display Bus: PCIe PCIe Lane Width: x16 VRAM (Total): 512 MB Vendor: NVIDIA (0x10de) Device ID: 0x0613 Revision ID: 0x00a2 ROM Revision: 3172a Displays: And it shows the non-prerelease driver: NVIDIA GeForce 9800 GTX+ OpenGL Engine Vendor Name NVIDIA Corporation Version 2.0 NVIDIA-1.5.34 GL Shading Language Version 1.20 Renderer Name NVIDIA GeForce 9800 GTX+ OpenGL Engine OpenGL Extensions OpenGL Limits Display Mask 1 (0x00000001) Renderer ID 140808 (0x00022608) Off Screen No Full Screen Yes Hardware Accelerated Yes Robust No Backing Store Yes MP Safe Yes Window Yes Multi Screen No Compliant Yes Buffer Modes 15 (0x0000000f) Color Buffer Modes 167805440 (0x0a008200) Accum Buffer Modes 8421376 (0x00808000) Depth Buffer Modes 3073 (0x00000c01) Stencil Buffer Modes 129 (0x00000081) Max Aux Buffers 2 (0x00000002) Max Sample Buffers 1 (0x00000001) Max Samples 4 (0x00000004) Sample Modes 3 (0x00000003) Alpha Sampling Yes GPU Vertex Processing Capable Yes GPU Fragment Processing Capable Yes Total Video Memory 536870912 (0x20000000) Total Texture Memory 501348864 (0x1de1fa00) Still the slower than the 7800GT. Has anyone else done this comparison?

mitch_de Posted December 16, 2008 Share Posted December 16, 2008 Forget Xbench OpenGL Values !!!! For example an GMA 950 performes better in XBench than Nvidia 6600 GT - so Xbench OpenGL isnt an good OpenGL / GPU test ! Get OpenGLExtensionsviewer and there to BEnch, use an higher resolution >= 1200x800 and you see real differences between GPUs. Very fast cards should be compared with Multisampling*4 - higher GPU loads, also more differences. http://www.realtech-vr.com/glview/download.html Link to comment https://www.insanelymac.com/forum/topic/140810-7800gt-9800gtx-loss-in-performance/#findComment-1001782 Share on other sites More sharing options...
s800 Posted December 16, 2008 Author Share Posted December 16, 2008 Okay, so Xbench does suck, but I'd sure like to think that Quartz would be faster. Aperture is slower as well. Granted, Quartz Extreme is opengl, but if the UI, OpenGL and Core apps don't have a benefit with a newer card... what's the point?

bucckevin Posted December 31, 2008 Share Posted December 31, 2008 having the same problem with a 9800GT tho. it's not just the benchmark, i can notice it in world of warcraft. it doesn't perform any better than my 128mb Quadro 540. playing wow games on windows for now.
