K7 µarch | |
General Info |
K7 was the microarchitecture for AMD's K6-III line of microprocessors as a successor to the K6-III. K7 was superseded by K8 in 2003. K7 was used for AMD's Athlon and Duron families of processors.

Codenames
Core | Family | Description |
---|---|---|
Spitfire | Duron | 1st generation Duron |
Morgan | Duron | 2nd generation Duron, introduced SSE & Hardware data prefetcher |
Camaro | Duron | Former corename for 2nd generation (Morgan) mobile processors |
Appaloosa | Duron | Scheduled to be 3rd generation, scrapped for unknown reasons |
Applebred | Duron | 3rd generation Duron, produced on a newer 130 nm process |
Process Technology
K7 was originally manufactured on AMD's 180 nm process. By late 2002 AMD transition to a 130 nm process.
Architecture
K7 was a relatively new design by AMD which marked a departure from the aging Socket 7 and Super Socket 7. The new architecture introduced a number of major changes including a new propitiatory unified Socket A.
Key changes from K6 / K6-III
- System Bus
- K7 utilizes the Digital Alpha EV6 system bus interface
- AMD licensed the technology from Digital allowing them to independently develop their own chipsets and motherboards without paying licensing frees to Intel for their Slot 1 GTL+ bus. This does consequently meant incompatibility AMD's motherboards and Intel's motherboards.
- The EV6 utilizes double data rate (DDR) doubling the effective data transfer rate of the bus speed.
- 100 MHz bus = 200 MT/s
- K7 utilizes the Digital Alpha EV6 system bus interface
Memory Hierarchy
AMD used a split L1$ and a unified L2$. While originally K7 had an L2$ controller on-die with the actual cache off-chip, AMD moved the L2$ on-die the following year.
- Cache
- L1 Cache:
- 64 KiB 2-way set associative instruction, 64 B line size
- 64 KiB 2-way set associative instruction, 64 B line size
- L2 Cache:
- 64 KiB 16-way set associative, 64 B line size
- Unified
- 7 cycles latency
- 64-bit data bus
- exclusive
- Note original Athlon models did not feature an on-die L2$, instead cache was implemented off-chip with a built-in controller supporting up to 8 MiB OF SDR/DDR SRAMs. Full tag was used for 512 or less KiB memory and partial tag for larger caches.
- L1 Cache:
- TLB
- ITLB
- 24-entry, dual-port
- DTLB
- 32-entry, dual-port
- STLB
- 256-entry
- ITLB
Both AMD's and Intel's original models did not feature on-die L2$. When compared to Intel's original Pentium III L1 which was 32 KiB (albeit at higher associativity), K7 had superior performance due to having 4 times as much cache. By the following year AMD moved the cach on-die. With the introduction of the Coppermine models, Intel moved the L2$ on-die as well with half of K7's latency. This change allowed Pentium models to outperform Athlon for certain workloads.
