There are exceptions. Looks like it's 2/3 of total on 7790 Bonaire (or/and with this driver version): Max memory allocation: 1398276096 Global memory size: 2084569088 Max pipe packet size: 1398276096 Max global variable size: 1258448384 Max global variable preferred total size: 2084569088 Also getting really weird results on 7730 (or was it 7750?) Capeverde with 1 GB DDR3, which reports: Max memory allocation: 595329024 Global memory size: 1018167296 58% of total? Even weirder: larger allocations succeed, including in excess of 1 GB total, and appear to silently use host memory. Maybe use of host memory is supported for this device because it's similar to what's found in AMD APUs. Alexander
