The 6x86 is superscalar and superpipelined and performs register renaming, speculative execution, out-of-order execution, and data dependency removal. However, it continued to use native x86 execution and ordinary microcode only, like Centaur's Winchip, unlike competitors Intel and AMD which introduced the method of dynamic translation to micro-operations with Pentium Pro and K5.
With regard to internal caches, it has a 16-kB primary cache and is socket-compatible with the Intel P54C Pentium. It was also unique in that it was the only x86 design to incorporate a 256-byte Level 0 scratchpad cache. It has six performance levels: PR 90+, PR 120+, PR 133+, PR 150+, PR 166+ and PR 200+. These performance levels do not map to the clock speed of the chip itself (for example, a PR 133+ ran at 110 MHz, a PR 166+ ran at 133 MHz, etc.).
The 6x86 and 6x86L weren't completely compatible with the Intel P5 Pentium instruction set and is not multi-processor capable. For this reason, the chip identified itself as a 80486 and disabled the CPUID instruction by default. CPUID support could be enabled by first enabling extended CCR registers then setting bit 7 in CCR4. The lack of full P5 Pentium compatibility caused problems with some applications because programmers had begun to use P5 Pentium-specific instructions. Some companies released patches for their products to make them function on the 6x86.
The first generation of 6x86 had heat problems. This was primarily caused by their higher heat output than other x86 CPUs of the day and, as such, computer builders sometimes did not equip them with adequate cooling. The CPUs topped out at around 25 W heat output (like the AMD K6), whereas the P5 Pentium produced around 15 W of waste heat at its peak. However, both numbers would be a fraction of the heat generated by many high performance processors, some years later.
The spine of the Cotswolds runs southwest to northeast through six counties, particularly Gloucestershire, west Oxfordshire and south western Warwickshire. The northern and western edges of the Cotswolds are marked by steep escarpments down to the Severn valley and the Warwickshire Avon. This feature, known as the Cotswold escarpment, or sometimes the Cotswold Edge, is a result of the uplifting (tilting) of the limestone layer, exposing its broken edge. This is a cuesta, in geological terms. The dip slope is to the southeast. On the eastern boundary lies the city of Oxford and on the west is Stroud. To the southeast, the upper reaches of the Thames Valley and towns such as Lechlade, Tetbury and Fairford are often considered to mark the limit of this region. To the south the Cotswolds, with the characteristic uplift of the Cotswold Edge, reach beyond Bath, and towns such as Chipping Sodbury and Marshfield share elements of Cotswold character.
The area is characterised by attractive small towns and villages built of the underlying Cotswold stone (a yellow oolitic limestone). This limestone is rich in fossils, particularly of fossilised sea urchins. Cotswold towns include Bourton-on-the-Water, Broadway, Burford, Chipping Norton,Cricklade, Dursley,Malmesbury, Moreton-in-Marsh, Nailsworth, Northleach, Stow-on-the-Wold, Stroud and Winchcombe. Bath, Cheltenham, Cirencester, Gloucester ,Stroud and Swindon are larger urban centres that border on, or are virtually surrounded by, the Cotswold AONB.
The town of Chipping Campden is notable for being the home of the Arts and Crafts movement, founded by William Morris at the end of the 19th and beginning of the 20th centuries. William Morris lived occasionally in Broadway Tower, a folly, now part of a country park. Chipping Campden also is known for the annual Cotswold Olimpick Games, a celebration of sports and games dating back to the early 17th century.
