| | 3DNow! - Wikipedia, the free encyclopedia |
 | | Professional, which was introduced with the Athlon XP processors; this version basically integrated the full SSE1 technology from Intel and combined it with its own 3DNow!. | | | Using the traditional x87 instructions meant that no operating system modifications had to be made to support 3DNow!. | | | Later, Intel would add similar (but incompatible) instructions to the Pentium III, known as SSE. |

| | Since the most common 3D instructions are contained in the 3DNow instructions, the effect is increased 3D performance with software optimized for 3DNow technology. | | | So, to experience the gains of 3DNow, the game must either be natively coded for it or make use of 3DNow optimized drivers or API's. | | | DirectX 6.0 will provide support for 3DNow instructions, so games which are only designed to work with the API itself will then automatically take advantage of the 3DNow instructions with DirectX6. |

| | AnandTech: SSE vs 3DNow |
| | The problem with the 3DNow implementation is that the two SIMD operations which are to be executed simultaneously cannot be both additions, or both multiplies. | | | Since SIMD works by packing as many 32bit FP values as possible (in the case of 3DNow, 2, SSE, 4) into the operand registers (or memory) and then performing the operating on these registers, it is evident that 3DNow can only perform two normal floating point operations per operation. | | | The reason I say per operation rather than per clock is because the current 3DNow implementations found in AMDs processors can perform 2 SIMD operations per clock. |
