On my 5850 clocked 950/300 I get this in phoenix using aggression=13, BFI_INT, VECTORS *;
Workload = 64;
340 MHash/s
Workload = 1024;
363-364 MHash/s
On a Win XP x86 professional using CCC 11.2 and SDK 2.1.
Using a Sapphire 5850 1Gb Toxic, just FYI :3

How does it do with no worksize setting?
Good question, it is better again ... 338~340 ... so going to edit title of thread.
Can get rid of worksize flag ... less crap on CLI is good.

25Mhash slower here.
Okay, maybe it is just my particular set-up on that rig ...
ubuntu 10.10, SDK 2.1, fglrx 11.2 (AMD drivers built/installed as .deb packages), HD 5970 clock 775/300

Okay, here's a tip for free for anybody using the Cypress chip (5870, 5970) ... it seems the new phoenix miner 1.3 goes a bit faster using worksize=64 now not worksize=128 ... and it is same on new poclbm also i think ...i.e., -w 64 is now better than -w 128 ... must be something to with the BFI_INT flag being enabled ... check it out (I waited until new difficulty is set to release this info but have been using this for a few days already).
... you can thank me later with tips
EDIT: after more testing as per discussion below NO worksize flag or setting (default) is better than -w64 and -w128
